Receptacle issue on 120V

[gwg]

Looking for thoughts on a weird issue. The trailer has power in all receptacles when plugged into either 30A or 50A shore power, when I get back home I reduce down to just 120V just to keep the refrigerator running.
When I do this I no longer have power in a few receptacles. I did have the extension cord plugged into a GFI source and I have heard that "back to back" GFI's can cause issues as these receptacles are wired to a GFI breaker.
I tried power from a non GFI source and same issue.
I think its fair to say the breaker and the wiring is good due to all systems go while on the 30A / 50A power.

Thoughts?

Do you have the factory 1,000 watt inverter? Those three or four outlets usually have a blue sticker beside them and will not have power unless the inverter is running off the batteries.

We completely rewired out 2014 Classic, so our electrical is different than standard. One must remember that the 50 amp service is two legs of 120Vac, each with a capacity of 6,000 watts. When connected with an adapter cord to 30 amp service, those two legs are connected at the trailer end and are sharing the one 3,600 watt connection on the pedestal. The 50 amp to 15 amp extension cord adapter does the same thing but one can only draw about 1,500 watts.

I appreciate the information. I just don't recall this issue prior, but it makes scene.

Hello gwg

Usually this sort of thing is caused by the adapter you use to connect to 120v only. The adapter must be wired so that the incoming "hot" line is connected to both of the outgoing "hot" lines, not just one. If one of the lines is left unconnected, only about half of the circuits in the trailer will work.
