Like I said, I ran the hot wire to an empty slot on the 12v board, and ran the ground wire to the ground wire buss in the 120v side of the breaker panel (be sure NOT to use the neutral buss). The 120v ground buss is connected to the 12v ground.
How is connecting 12V and 120V grounds safe???? If the 120V uses the ground as the neutral you'll be sending 120V into the negative power path of the 12V system right? (assuming it's negative ground like a car)
Even though it sounds "bad", in reality the 120V AC equipment ground IS bonded to the trailer frame.
At the same time the 12V NEGATIVE terminal is ALSO BONDED to the trailer frame.
So in a sense does not matter as to where you find a place to tie in for 12V NEGATIVE.
In practice however, it IS bad form to MIX high voltage (120V) and low voltage (12V) systems in side the same junction box..
The converter power panel is designed to maintain separate high voltage and low voltage sections and for good electrical practice the OP SHOULD MOVE the 12V NEGATIVE connection from the 120V section.
The OP needs to look BEHIND the power panel, there WILL be a bundle of 12V NEGATIVE wires (these wires should all be WHITE) all connected via one huge wire nut..
Low voltage connections (in the past, not sure if that is true now days)were/are treated differently by NEC in the fact that there was no requirement for a enclosed junction box for low voltage connections..
That's where the OP should have tied in at..
