Breaker in RV Keeps Tripping?

I live in an RV that has a double pole 15 amp breaker that's tripping. The load is 8 plugs and 2 110 volt AC window units. The breaker box is full, so can I install another breaker box and split up the load?

Another box would probably require another feed, maybe another generator or power source.

The breakers is protecting the wire within the walls. It does not allow more current to flow through them than what they are rated for. This is to prevent overheating.

volts times amps equals watts. 240 volts times 15 amps equals 3600 watts. This is where your breaker will start tripping. If each A/C unit is less than 2880 watts (12 amps) (80%) then they can be run individually but not together.

An electrician is always your best bet.

I apologize

I missed that the AC units were 120 VAC.

This means that they must be less than 1440 (120 x 15 x 0.8) watts and not run on the same leg at the same time.

Again, please consult an electrician.
