Troubleshooting Electrical Voltage Drop

The meter is on the pole near the driveway. The line from the meter split bolts to the house and 2 shops. The house and shop 1 both have no problems, shop 2 has proper voltage on both phases until a load is applied. Once a load is applied there is a large voltage drop on 1 of the phases.


My question is what could cause this voltage drop on one phase. All that's in the sub panel is a 2 pole 20a, 1p20a, 2p50, and those feed a 220 plug, a 120v plug and a plug for a welder. The plugs, breakers, and wires to each have been replaced.

A poor connection.

A possible culprit here could be a poor electrical connection that is high resistance and when placed under any load produces a significant voltage drop. Be warned that a poor connection causing voltage drop produces heat.

Have an electrician look into this or have your utility check the connection at the pole.
