Im working on an RV/trailer with a standard 120/240 V load center fed by a shore-power cord that plugs into a standard 50 Amp 120/240V receptacle. My question is whether or not the grounded conductor (neutral) should be bonded at the panel in the trailer, or be left floating?
The trailer spends half its time connected to a standard RV hookup on the side of a building. I believe it should be left floating for this situation; it’s basically just a sub-panel fed by the building’s main panel.
However, it spends the other half of its time connected to a pair of small portable generators (2 Honda EU2000s in parallel operation) which do not have a bonded neutral. So, in this case I pressume the panel inside the trailer should have a bonding jumper in place.
I can’t very well have folks taking the bonding screw in and out depending on the power source, so I have to choose between leaving it in or taking it out all together. What’s worse: having no neutral bonding point, or having 2 neutral bonding points?
