So this is the first time I’ve really ran into a neutral back feed on 4 different breaker panels. What ties them together is they are all on the same meter stack off of a 1200A Meter Base. All of the Breakers on the right side of my breaker panels (Even Numbers) can be turned on and off with no back feed to the neutral. The Breakers on the left side of my breaker panel (Odd Numbers) can be turned on somewhat if not AFCI/GFCI breakers tripping obviously. As soon as I turn on 1 breaker from my left side of my panel it causes a back feed through my neutral.
I’m thinking that the problem is within my meter stack, but is it possible for an induction short in my exhaust fan of even one unit to cause this back feed on my neutral. I have not disconnected my SER from my main lugs just yet and tested voltage on the four units. Yet, testing voltage incoming with all breakers off is 240V good to go. 120V for each hot, again, ready to go.
Does anyone have any other ideas as to what could be causing this? It’s possible that 1 of the 4 units could have a neutral ties in to a hot that’s causing that back feed just wanted to see if anyone had any ideas on how to isolate what could and could not be the issue, i.e. breaker panel or meter gear.
I am using the new BRP Plug in type Neutral Breaker Panel if anyone suspects that has something to do with it. These panels are fairly new and not sure if the neutral plug in can fault causing that back feed off of the breaker. This would be my 174-178 units that have been fired up off of these panels so not suspecting it to be a BreakerPanel issue.
Any knowledge or criticism would help...
Thanks guys,
