Hello Everyone,
I have a magnum 2812 inverter/charger. With the new electrical code at Florida Marinas the ground fault is set to trip at 30 ma at the pedestal. I have gone through my system and does not trip when the inverter is disconnected. It will also not trip if I power the inverter, before activating the breaker that sends the power from the inverter to the panel. If I try to leave the breaker that allows the inverter back to the panel on when powering up from the pedestal, it trips the pedestal. I know others have said that if any circuit that shares a neutral bus bar from before and after the inverter will cause this. I am under the impression this should have caused a trip when the inverter was taken out of the equation.
With that, it has led me to believe that maybe the neutral to ground relay is slower than the pedestal when power is applied, and causing the trip. This is why when the inverter is first powered up, before the breaker is turned on to allow the power through, it has already activated the neutral to ground relay.
What are your thoughts? Am I on the right track, is it a shared neutral bus issue, or something else? Any help would be greatly appreciated.
Thanks,
Paul
