Factory 110v stranded ground
Posted: Sat Oct 27, 2018 10:10 am
I noticed today that my 110v panel has two grounds. The ground inside the 10awg romex that feeds the panel, which is to be expected. I also noticed there is a separate stranded ground wire that also attaches to the ground bar in the panel. I imagine this stranded ground is bonded to the frame of the trailer somewhere.
Since the panel in an RV works like any other sub panel, why the separate ground bonded to the trailer frame? I understand the 12v stranded ground bonded to the neutral bar attached to the skin in the pic, but why is there a 110v ground wire bonded to the frame?
