An electrical system puzzle
We have a 2012 Keystone Cougar 5th wheel with a 50amp system. This rig is brand new to us, but we have several years of travel trailer experience. The rig has a WFCO power distribution center and a WF...

depending on the dogbone your using to go from 240V 50A to 120V you could end up with a GFI that trips. A 50A service is two legs of 120V. And depending on how you go from the 50A/240 to 120 you could either end up with only one leg powered or the two legs tied together. and how it ends up getting configured can be incompatible with a upstream GFI outlet. GFI outlets will trip if they see ground/neutral bonding downstream or some aspects of a 240 trailer to 120V trailer adapter. In fact some of the 50A/240V to 30a/120 adapters will say NOT compatible with GFI outlets.
Even if some non standard adapter connects to only one hot the upstream GFI should still see balanced hot and neutral current. And most users would be less than thrilled with AC power in half of the rig and would soon find a standard RV adapter.
Plugging a RV into a GFCI circuit and trying different appliances is a good method of checking for a ground fault.
The only adapter that I'm aware of that will trip a upstream GFCI is the cheater cord and probably shouldn't be used even with non GFCI plugs.
