I have a Single Phase Power box for a townhouse. When I read voltage across the Hot legs (A) and (B) to ground I get 123 volts with the main breaker turned off. With all the circuit breakers turned off and powering up the main breaker to the panel I still have 123 volts across both (A) and (B). As I start to turn on the branch circuit breakers on to each Outlet, Light, Garbage Disposal, Washer etc..... The voltage changes but it ranges from (A) -- 134volts, (B)--- 104volts, as i keep going down the panel turning circuits on the voltage changes and never evens out back to (A) 123volts, (B) 123volts, or anywhere close to it. The worst I have seen on this panel is (A) -- 154volts, (B) -- 94volts. The panel did not have a ground on it from the ground rod which I corrected and tied it into the ground strip and Jumper'd over to the neutral bar.
Everything I have read about this issue is that it is a neutral problem and I thought it was a floating neutral at one time but had the feeling it has always been a neutral issue. But as I have researched this I have come to understand that it is more than likely the PoCo that has a broken neutral going to this panel on their end not on my end... Is this correct.? Is there another issue I should be looking at.?
Any assistance would be greatly appreciated. Thanks
