Isn’t the 50 amp service really two separate 25 amp circuits so that there is never more than 25 or so amps on one leg? This way you really only have 50 amps in the power cord running from the power supply into the RV but from there on there are basically separate runs throughout the RV. I assume this is like a power panel at your home where you would have a couple hundred amps or so coming into the panel but anything over 30 amps from the panel is only when two ore more circuits are combined like for an air conditioning compressor?
That is why you almost never see more than 30 amps unless an RV has two air conditioners because all that amperage is to allow both to run at the same time.
I don’t think a manufacturer would risk a fire potentially killing people by knowingly running insufficient wire gauge regardless of what they could get away with and I think they would be exposed if they did.
I know they do everything on the cheap and under size lots of things but would be shocked to learn they send these things out of the factory with fire risk. I hope I am not wrong.
Can some of you electrical experts out there shed some more light—no pun intended? [emoji3]
