240/120 Main Electrical Panel Uneven voltage

I have an electrical panel in my small cabin that has uneven voltage on the 2 incoming legs from the service disconnect. 1 Leg has 165 volts and the other 80 volts. This a high incidence lighting area. Could the Main elec meter be damaged?

You should have 240vą10% between the two incoming legs. If you have 245v it is within spec so it would seem to be a neutral problem but wait for the pros.

Unplug all electronic equipment.

I take it you have measured the voltage at the most upstream place you could without breakkng the meter seal.

Given that the hot to hot voltage is always about 240 and the hot to neutral voltage on both sides always adds up to about 240, call the power company stating that you have an "open neutral."

Yes, do not call the customer service number. Call the emergency number.

We really don't know for sure how the OP was measuring the voltage, he never said he was measuring hot to neutral or hot to ground. That being said, I would also suspect a loose or bad neutral connection.
