In case anyone is still interested in this thread, This is the response we received from Eaton. We still plan to have the power company out to make sure there’s no issue on there end. Still doesn’t make a lot of sense but I’m not entirely sure where to go from here.
As discussed, please advise them to move the GF breakers to a different circuit in the LC. See below:
Eaton 30/2 and 40/2 breakers with an tripping issue.
- 3 phase 120/208V systems – breaker may trip even without load wires connected to it. Usually breaker will trip as soon as it is reset.
- 85% of the time, moving the beaker up/down one spot in the panel resolves the issue or change wiring on the load side of the breaker feeding the loadcenter. Doing so changes which 120V phase (leg) feeds power into the breaker’s circuit board. This is due to power quality issues present on one phase and not the other.
