Here are questions related to Troubleshooting Circuit Breaker Problems.
I recently purchased a house, and it is clear that the previous owner had not always done things correctly. My present concern is that there seems to be 14 gauge wire running off a 20 AMP breaker. I believe this is a code violation, and more importantly a fire risk. I would rather not open up the walls to replace the wire. Assuming the circuit would be OK on a 15, can I just have the breaker replaced? Is that an adequate solution?
By Susan Sanders-Kinzel 02/02/2005
Yes, that is a code violation and a fire risk.
And it invalidates the insurance.
To fix the problem,
1) get a breaker from the same brand and series but with a 15 Amp rating
2) turn the 20 Amp breaker off and pull it out.
3) swap the wire, that goes to it, over to the 15 Amp breaker
4) Make sure the 15 Amp breaker is turned OFF
5) insert the 15 Amp breaker
6) make sure the 15 Amp breaker is inserted fully and looks level with the other breakers
7) turn the 15 Amp breaker on and test the appliances or outlets that are fed from it.
If you forget point 4), there will be scary sounding arcing and sparking that could startle you into falling off your ladder or chair.
The circuit breakers in all my four bedrooms are tripped and cannot be switched on, but the bathrooms are OK. I don't think the breakers are bad or the circuits are shorted because they are individual, and cannot all be bad at the same time.

This just happened to us. We had to call an electrician. Some time ago my Dear Hubby changed out a light switch and because he is colorblind got the wires mixed up when he hooked it back up. Any way our circuit breaker went to ground and we needed an electrician to fix it.
I plugged in a vacuum cleaner in the living room and had other things going (TV, etc.) and blew the circuit. I unplugged everything and tried to re-set the circuit breaker (switch to off then back to on position). However, the switch will not switch completely to the off or on position. I can move the switch in either direction, but not enough for it to stay there. It goes right back to the middle. Can someone tell me if there is anything else I can try, or does thia mean I have to pay to have an electrician come in and repair this? Many thanks in advance!

Thanks for your post. I was able to successfully change a circuit (15) by using your directions. It solved my problem. I noticed some people saying you should not do because you could burn your house down and such. But if they follow your instructions and turn off the main. It is relatively simple to do. I just made sure I had rubber handle needle nose to guide the house wire back into the new circuit as well as a big rubber handle screwdriver. Thanks for people like you. Bret
I asked an electrician to fix the circuit breaker in my house because it was tripping. So he connected 4mm wire between the neutral and the earth. All was well for 2 days, then it kept tripping whenever you pull out the wire. What could be the problem? Could it be a floating neutral?
By Justine from SA
By REE 04/18/2010
Some where on that circuit there is a bad neutral. You should not have to add the wire to it? Did you nail in something to wall and then it happened (*maybe nicked the neutral)?
Neutral wire could have broken.
Wire nut could have come loose in junction box.
Is the line overloaded? running too much stuff.
I just moved into a new house a couple of weeks ago. It was pre-wired for cable. I had my cable installed last week. Ever since they installed the cable my breaker for my bedroom is tripping intermittently. I had the electrician at my house. He said unless something happens when he is there he cannot find the problem. Is there anything I can do on my own to try and solve this problem? I had it trip 3 times this morning and it is getting very frustrating!
I think you need a new electrician !!! Any electrician who knows their stuff doesn't need to 'wait for the problem to occur' in order to have a clue what the problem is ... Being this is a new home I suggest whoever did the installation find and fix the problem at no charge with threats of the Better Business Bureau, etc if they hum hah around about it !!!
We recently purchased an old home (105 years old) and one day half of the lights on a circuit stopped working. They stopped when I turned on a sconce and it shorted and blew the circuit breaker. Half the lights on the circuit went out, not to be seen again.
I have checked all of the old outlets and replaced them as I thought I might be shorting back through the common. I am stumped as to what I should do. I had an electrician come out and take a look and he is stumped as well. Any advice?
Rick from Iowa (in an old home)
One of the below answers is probably correct, but I think the real answer is to call in a different electrician. There is no problem of this type that a competent electrician should not be able to find and fix; they will have tools like the tracer mentioned below. And as ThriftyFun wrote, it's not safe to just work around this; it needs to be fixed.
I have tried every breaker in the box, but cannot turn off the stove top unit. Help!
By Sandi/Poor But Proud 04/20/2015
Bruce is right. My feeling is that a stove top is an 80's appliance. When I had mine, it was wired directly to a box under the house. Yes, get it fixed and quick. Hope these both helped.
What would it be if you turned off your main breaker, then turned it back on and there was one breaker to a bedroom that was tripped and could not be turned back on?
By Patty P.
By Bruce S03/26/2015
A standard breaker will trip on an overload. This is often a short circuit between hot and ground.
The short circuit can be part of your household wiring. But that probably hasn't changed. I have heard of someone hanging a picture by driving a nail in the wall and going through the electrical cable causing a short.
I would unplug everything fed by that circuit before attempting a reset.
In case you don't know: to reset a breaker first turn it off and then back on.
I woke up this morning to one entire side of my kitchen not working including the main overhead light and dining area light. The other side has my large items and it appears they are fine. I checked my box and one of the circuits had tripped. I tried to reset it, but it would not. It would trip again and it sparked. I have unplugged and turned everything off and it still will not stay on. Any suggestions?

Circuit breakers wear out, and I suspect that this one has done so. Get an electrician to come in and replace it. You might also get him to check on why this breaker has worn out. Mine wore out because it was continuously tripping off because there were far too many outlets on the circuit. Eventually, I will get another breaker or two installed so that this circuit is not overloaded. If this was not your issue, and it happened suddenly, you may have some other wiring malfunction that could be dangerous.
We had a storm and somehow ended up with a leak in the roof. The leak is directly over the breaker box. The electricity had gone out during the storm. When the power restored only some of the rooms had power. My concern is, could the wet breaker box lead to a fire?
By Louise B. 02/02/2015
Any time you have water near electricity, it is trouble. Call an electrician at once to repair the problem. This is not something to attempt to fix yourself.
I keep getting a buzzing sound from breaker, it doesn't shut down just buzzes now and then.
By David B from Lansing
By Bruce S01/27/2015
Dinah is correct, an electrician is needed. The buzzing is caused by moving parts, either a loose connection (internal or external) of the breaker or bad contacts within the breaker. I would get it checked quickly. loose/bad connections can be heat generators.
We are looking to purchase an older home built in 1994. We had the inspection today and when the inspector used his little surge tool to test all the outlets, not one breaker flipped. The house has power and all seems normal otherwise. The seller doesn't have much money to make repairs, we only have 10 days to back out. Could this be something that is extremely expensive to repair? Or could it be a simple solution? We are requesting an electrician come and evaluate the issue.
By Melanie C
By Louise B. 01/21/2015
Having an electrician come is by far your best solution to this problem. And a house built in 1994 should have no electrical problems unless someone without any electrical knowledge did some modifications since the house was built. I would be suspicious.
I have a tenant that blew a breaker. I reset the breakers, but the power still will not come on to that room. The last time this happened, I replaced the breaker and that solved the problem. Unfortunately, this time that solution did not work. Any suggestions?

Is there a main power switch that controls the power to the whole home? I used to throw that switch sometimes when I lived in a mobile home, and the switch was outside on a power pole. Perhaps you have a main switch in your house -- I'm thinking everyone should have one, but that is just a guess. If that is not the problem, perhaps you should call an electrician. When I throw a breaker, simply switching it back on again restores the power. If it repeatedly goes off (over a period of several years), one needs to replace it, as they wear out.
I'm house sitting and was watching TV in the familyroom, it was daytime, and no other appliances or anything were on. Suddenly the TV, cable box, and surround sound just shut off. I thought at first the power went out so I checked some lights, they worked. It was just the power in the family room that was out.
So I went to the breaker box and sure enough the switch for the family room was between off and on. I flipped the switch on and went back to check if that worked, it didn't. So I went back and tired it off and then back on, still didn't work.
What do I do next? I can't reach the owners right now, do I need an electrician to come out? Could it just be taking a while to rest?
By Louise B. 01/06/2014
I would call an electrician. If the circuit breaker won't reset, either it is worn out and needs to be replaced, or some problem that caused the thing to flip in the first place has not been resolved. Since the breaker seemed to flip "for no reason", I would call an electrician. You may have something dangerous going on.
I recently moved into my condo and I noticed that when they painted the walls the painters went over the outlets so some were filled with paint. I decided to change out the outlets so I went to a hardware store, purchased some standard outlets and watched a bunch of YouTube tutorials.
My first outlet had the ground wire and instead of having 2 black and 2 white wires there was one of each and they were solid, not cut just a solid wire. I went back to the hardware store and they said to just connect it the same way on the new outlet. I went home and did that.
All the outlets run through the same wires. It concerned me though that only one outlet had a ground wire, is that OK? Also I bought the light indicator to let me know everything was connected OK and got the code that it was. Now, 2 days later, with only a lamp connected and on, the circuit breaker went off. I tried turning it back into the on position, but it keeps going off. It won't stay in the on position; what should I do? I am hoping it's only the circuit breaker.
By Carlos from Chicago
By Louise B. 12/06/2013
I agree with the previous poster. I think that it is time to call in a certified electrician before you start an electrical fire. These guys go to school and train with qualified journeymen for their trade. They do not get their info from hardware store clerks and Youtube.
I had to change the outlet in the bedroom because it almost burned. I put in the new outlet then went to turn on the main circuit breaker. It was so hard it to move that it broke off. Now everything is working except for my refrigerator and an outlet near it. Any suggestions?
By gbk 10/13/2011
You can replace the circuit breaker. The main breakers are very hard to push and you apparently have an old one and the plastic was brittle. You need to know what kind of breaker box it is and take it with you and if it isn't too old the hardware co may have one or an electrician can tell you where to go. He just might help you because the job is really minor. The major problem is the short in the broken breaker.
I have an electrical outlet that runs all my outside and garage outlets, about 9 outlets all together. It has a trip fuse on it and it keeps tripping.
I have unplugged everything from all the outlets and it keeps tripping. I have replaced the outlet, still tripping. The fuse box does not trip; it is working.
I had a outside pool pump plugged into the backyard outlet and the pump kept shutting down and starting when it was supposed to remain on. I replaced the pump. Would it be possible for that outlet to be damaged because maybe the pump overheated?
By Snake from Hope Mills, NC
By Grandma J 06/09/2010
Time to get an electrician out before you have a fire your someone gets hurt. Sounds like faulty wiring.
Any time your trip action happens, it is for a reason like over load Don't just restart it with the same things again.
If a #12 wire is connected to a 15 amp breaker, can I assume that it is safe to replace the 15 amp breaker with a 20 amp breaker?
By Douglas from Sacramento
By PEDRO E. ALEQUIN 01/08/2010
Changing just 5 amps causes more resistance, can double temperature of wire. wires may over heat and cause FIRE! Please get knowledgeable help. Not a DIY Project.
I turned off my main breaker to add a socket out back in the garage. It just seemed easier. When I finished and came in to turn on the main, my furnace thermostat breaker kept tripping. I checked the wires and the thermostat, everything looked fine. Even though the thermostat was fine I ended up replacing it a few days later since I couldn't find anything else wrong. It worked. My breaker stopped tripping and all went back to normal. I again turned off the main breaker today and the same thing happened. Except now if I disconnect the thermostat it keeps tripping the breaker still if I reset it. What could be causing this? Why would using the main breaker cause problems with only this breaker? Btw, I replaced the breaker thinking it was the problem, it still didn't help.
By whipzend 
By Bruce S05/20/2015
If I understand correctly, you have replaced the breaker and the thermostat. With these changes, the breaker continues to trip. Even with the thermostat unwired and the wires separated and taped, the breaker trips.
From this information, I would assume that your wire is shorted somewhere. Most likely at one end. (Often damaged when stripping back jacket of cable during installation).
There was a period of time when the breaker was not tripping but this ended after killing the main breaker.
When you shut the main off the second time, did you open the panel or the thermostat to reveal the wire connections at either end? Could this cable have been bumped? (a slight movement of the hot wire could seperate it from where it is grounding) I am concerned that the wire is shorting where it comes out of the cable or conduit at one end of the circuit and that by slightly moving the wire it is causing a short.
You probably already know that when you shut off the main breaker you still have power in your panel.
I would get an electrician to again kill the main to test the wires and repair them where necessary. Where it is arcing to ground, there will most likely be burn marks. I recommend an electrician because they have the tools, test equipment and knowledge.
Every time I turn on my TV all the power in my family room goes off and I have to go to reset the breaker for the room. I've tried different plugs and have the same result. I've unloaded the power strip and tried different ones too. It takes 2-3 resets with power going off before the TV stays on for good. Any suggestions? Is it the TV or the breaker? It's been a problem for a month now. Thank you!
By Dee F. 
By Bruce S04/30/2015
When you say you have tried different plugs, are these on different circuits? (different breakers?)
If it is not to cumbersome, I would try to plug the tv in on another circuit to see if it trips another breaker. If the problem continues then the problem is with the tv, otherwise it is with the breaker.
It sounds as though the problem is with the tv and once it warms up, you are fine. The problem sounds as though it is too much inrush current to your tv.
Often the capacitors fail in this type of tv. The flat panel LED / LCD tv's have electrolytic "pop can" capacitors in them that are less than an inch tall. These are part of the power circuit and are easily identified as bad because they bulge at the top and black stuff usually oozes out. These capacitors cost between $1 and $2 each to replace. If you know someone handy with electronics and a soldering pen, it is often a quick and easy fix.
Due to this loadshedding we have, my 45A circuit breaker for the stove keeps tripping when I switch it on. Can I replace it with a 10A breaker?
By Bruce S04/20/2015
A circuit breaker trips when the current through it exceeds its trip point. The higher the current, the quicker it trips.
The amount of current flowing through the circuit is determined by the load, in this case the stove, and changing the breaker does not restrict current flow, it would only shut it off.
Changing breakers to a different size is generally a bad idea. The breaker protects the wiring and if the breaker size is increased to a size more than the wire can handle, the wire can overheat.
The other day I lost electricity in half the house. I called Con Ed and they checked the wires and breakers. Everything seemed to be alright except the breaker to the furnance hums when we trip it and put it back on.

Time to call an electrician.
The circuit breaker keeps tripping when heat is set. There is no problem when set for cold, a/c.
By Nancy F. from Boynton Beach, FL
By Louise B. 02/21/2015
Heat draws more power than AC. If the circuit breaker keeps tripping, then it is overloaded. You have too much on the circuit. You need to call in an electrician to deal with this. It may be a minor issue such as replacing the breaker, or perhaps you need to shut other things off when you have the heat on. If breakers trip repeatedly, they wear out, and then will not stay on. This is actually a good safety feature.
I recently bought a 1992 Fleetwood mobile home. There are no fuses, it's a breaker box. I was running a space heater and TV when I tried to vacuum and the power all went out. I flipped all the switches in the breaker box inside the house and the breaker box outside. Now only a few lights will come on. I don't know anything about this kind of problem. We did just have the electric meter installed. And I read that the problem could be that the power company installed the meter incorrectly. Can anyone tell me what else may be the problem? Or suggest some way to fix it?
By Louise B. 02/14/2015
It seems from your post that you overloaded the circuits by using the three things at the same time. Space heaters take a lot of power. As well, if all the lights went out, you obviously had overloaded the entire system, and not just one circuit.
I quite regularly flip a breaker if I forget and run the microwave when I am making toast in the morning. There are far too many outlets on this particular circuit. However, the problem is solved by flipping the one breaker back on. I did have to have the breaker replaced, as this has happened repeatedly over the years, and breakers do wear out. The main breaker is in a separate box.
In the mobile home that I used to live in back in the 80's, the main breaker was outside on a box on a power pole. Is that how yours is? But anyway, if switching the breakers back on does not solve the problem, it is time to call an electrician. You do not have to diagnose the problem; just call one in, tell him what has happened, and let him do his job. They are trained to fix electrical issues.
Tonight I tried to turn on my radiator, but it uses a lot of power so it cuts off the power in my room sometimes causing me to have to enter the master bedroom's closet and flip the breaker switch back on for my room. Unfortunately, tonight when I tried flipping the switch back on, the power in my room will not come back on. I tried it several times keeping my radiator switched off. What can I do? I can't get it to work again. I'm so extremely upset about this.
By Lori from LA
By Louise B. 01/14/2015
Breakers that flip often will eventually wear out. This means that you have to get an electrician in to fix it. This is a very quick and easy job, and will cost very little, but it is not something that one can do oneself. I would also suggest that you get the electrician to check your circuits and see why the heater keeps flipping the breaker. It should not do so, but there may be too many other things on that circuit, and perhaps you will want to have additional circuits put in, or maybe just run the heater on a different outlet on a less "loaded" circuit. Please call an electrician to help you with this. Ask around amongst your friends and co-workers for a reliable one.
I recently replaced a light for a chandalier and the switch for a dimmer switch. They both work fine and no breaker is being tripped. The problem is that the adjacent room, which is on the same circuit breaker, is not receiving any power now.
Also, I don't know if this is relevant, but there was no ground wire on the chandalier to attach, just negative/positive.

This is not a good place to get advice for such a problem. Try googling for solutions and looking for sites that may have actual, factual electrical advice. Or, perhaps you have a friend who is a home handyperson who can help you out. However, if I were you, I would call an electrician. If you did the work you attempted properly, there should not have been a problem. If there is one, either you made an error OR there is a bigger problem with your wiring. Someone in the past has perhaps attempted home wiring and done it incorrectly. Your home could be in danger of catching fire from faulty wiring.
I have an American Switch Co. panel. I shut off the main and now it will not reset. It's a 100 amp service. I also cannot locate a replacement.

By Louise B. 11/17/2014
I always think that with electrical, it is best to call in a professional. It is, after all, something that, if things went wrong, could cause your house to catch fire. If you still wish to troubleshoot on your own first, perhaps you could try googling for info, and find a site that is more specifically for electrical problems or for home handypersons. My only experience with breakers is with the small ones, not the main ones. The small ones will eventually wear out if they flip off too often, and then have to be replaced. Could this be the problem with your main breaker?
I have a multi-circuit electrical control system that keeps tripping the main circuit breaker; how would you determine the circuit at fault?
By Louise B. 11/08/2014
I would call an electrician.
My home has partial power, I checked my circuit breakers, everything looks normal (I guess). How can I tell if my circuit breaker is broken or damaged? My basement has power and appliances work down there, but upstairs, my kitchen appliances and lights are out, and in 3 bedrooms, but I have power in 3 other rooms. WTHeck, I want to fix it myself, what do I do and how do I start?
By Pudding from Southfield, MI
By Louise B. 09/16/2013
Start by flipping the breakers on and off once or twice. Sometimes breakers trip, but don't look like they are tripped. If that doesn't fix the problem, call an electrician. You should not attempt anything electrical if you have no idea what you are doing.
I have just updated my bathroom and I have put six spot lights in, an electric fan, and an electric mirror. When I installed the lights and mirror I also put a dimmer switch on and they seemed to work OK, but three of the transformers to the spot light broke. I don't know if that has anything to do with dimmer switch.
Then my electric fan arrived and I made the mistake of getting a timer fan. This I found out needs a permanent live that I don't have due to me taking power from the spot light circuit. I think I've found I solution to that problem; I hope.
But the thing that is really puzzling me is I changed my light switch back to a normal switch instead of the dimmer, but when the spot lights are on my mirror loses power then when I turn them off it regains power. The mirror has its own permanent live with a switch, but this does come off the spotlight circuit as well.
When I had the dimmer switch they both worked together until I turned lights up to full, then the mirror would lose power. This seems to tell me that for some reason my breaker isn't giving enough power out to run all. Is this possible or is the another way around it?
By Grandma J 09/09/2013
First, are you an electrician. If not, get the advice of one. A dimmer switch, as they used to be, is different, depending on the use. They don't all work for every kind of appliance/light/light bulb. Make sure you have enough circuit breaker power for your bathroom.
You did not say if you have a GFI installed. That is a law for bathrooms, etc places where water is.
And please, check even if online for professional help. This Old House, The Handyman, are both good sites.
I am dog sitting for my parents for two weeks and I went to turn on the living room light at night to grab a few things before bed. It did not turn on so I tried the fan connected to it and that didn't work neither. So I went to the main bathroom (there are three bathrooms in total) and even that light and fan didn't turn on. There is also a washer and dryer in there, not in use, that said PF for power failure, but when I was in a bedroom upstairs trying to put my two year old to bed earlier everything in that one room is working fine so I didn't suspect a power failure. So I booked it all the way down stairs to the basement checking all the other lights and they were all working to the power box and all the fuses are working, so I don't understand. So I took a little walk outside the house to see if I can find another fuse box and I don't see anything. Btw I used to live here since I was 13 and everything worked fine. I have contacted my parents about this, but their trip is to early to come back, but I have told them about this. But maybe you can help me somehow.
By Frugal Sunnie 08/15/2013
Sometimes fuses will read as being live even though not supplying full voltage to a circuit; circuit breakers have been known to have failed to 'flip' even though there is a fault in the circuit that has caused a power cut.
The sooner a professional licensed electrician is in there, the better. Until then, shut off the power to the fuses/circuit breakers that feed that circuit. Yes, it will be inconvenient but not near as inconvenient as a fire!
Would changing a 15 amp circuit breaker to a 20 or 30 make it stronger?
By Geremy C.
By Harlean G. 07/27/2013
I am no electrician, by any means, but I do know that the purpose for the breaker is to trip the breaker if you overload the circuit. To circumvent this, could cause an electrical fire. If the circuit is supposed to have only a 15 amp breaker, it would be extremely dangerous to replace it with anything higher than a 15 amp.
Harlean from Arkansas
I am working on my basement. I've installed new lights on a breaker, laundry room lights on the second breaker, the third breaker has four outlets, and the fourth breaker has three outlets. All the breakers are new and 20AMP. I had no problem with running the first three, but the forth one keeps tripping, even when I've got only one outlet on it. Any suggestions?
Breakers are cheaply made in China. It is not unusual for one to be bad. Luckily they are cheap enough to try a new one.
I turned off the main breaker and when I turned it back on my pool equipment is not working.
By Frugal Sunnie 03/21/2012
This is not a good sign-have a licensed electrician out to troubleshoot this because it's not a simple fix. Something in the wiring between the pool system and the circuit breaker is chewed/frayed/broken or loose, and a professional will have the specialised tools to track it down quickly.
When I run my two window units at the same time why does the breaker arc/spark? It rarely trips the breaker.
By Shane O. 
I have changed the circut breaker and still have no power. What should I check next?
My circuit breaker is in the on position. The orange light on the breaker is on, and there is no power.
I have 20 spotlights fitted downstairs in my lounge, kitchen, and hall. It was done a month ago. The lights just went out and the breaker trip switch won't switch back on. Any advice? Thanks.
We purchased a new stove/oven a year ago, replacing one that was 20 years old. About a month ago, the circuit breaker started tripping whenever my wife was using the oven and more than one burner on the stovetop. We had an appliance repairman out to check the stove. He said the stove was drawing 49 amps with multiple burners on, and the 220V circuit breaker was a 50 amp breaker, that it had probably been weakened from the more powerful stove. He advised replacing it with a 60 amp 220V circuit breaker. Can I do that?
By William K.
I think I have an overloaded 15 amp breaker. The outlets work, but then they flicker on and off, as well as some lights. Can I replace the 15 amp breaker with a higher amp breaker to offset this?
Does a breaker trip due to wet/moisture near the circuit? The old fridge has been replaced and a new cable has been run due to the moisture from the AC before. That circuit has been changed, now the breaker trips after a short period. Any explanation why it keep tripping?
