I have a food trailer i’m Building, and am now at the testing and set up stage, and am having problems with my panels. I have a 20kw generator built in, feeding a main panel on one side, and a sub-panel on the other. Both bonding screws are removed from the panels. Every outlet has it’s own circuit and 15A gfci breaker. The 2 coffee machines are on 30a gfci breakers. The smoke detector is on its own CAFI breaker. The panels are Schneider Homeline Square D push on neutral.
When I energize the panels the cafi breaker is fine, the 2 30a gfci breakers are fine, but when I turn on anything on the other circuits, they trip.
Thanks for your help. kurt.
