I need to replace the main breaker panel in a unit I'm renovating. (Single family home, not apartment, USA) Prior to tearing anything out I wanted to turn off power. (of course)
This community has "power distribution towers" that service 6 to 10 units. Each unit has a breaker that turns off power to that unit. I found the breaker for my unit, but it was labeled with a note, "one leg not working." In marker under the breaker.
I checked the voltage incoming at the main breaker and got 120 on one leg and 118 on the other. Is this a problem? I called the power company. They said it was an issue that I had to call an electrician about.
The only 240 appliance that is intact is the AC and it works fine. Is this really no issue, a 2V drop? Should I be getting 120V from both legs and the 118V is a sign that something is amiss?
