I'm finally getting around to having to think about the 12 volt system & have a question for the people who have used a PD4045 in their trailers. It's a nice unit & I've figured out how I'm going to use it, but there are no provisions for grounding of the 12 volt circuits in the box. It looks like the internal lugs are all for the AC power.
Are people using a separate grounding block, lug or plate in the general area of the box to run a common ground point for the negative (-) side of their 12 volt systems from the battery?
Second question, the PD4045 uses the shore power inlet to feed the 120 volt breakers, but there are no provisions for running power to the "left" side of the device to run the battery charger & 12 volt stuff. The black wire of that side (left, charger, etc.) goes to the 120v lug in the AC side, but how are you pulling power from the inlet (shore power inlet, breakers) to that 120v lug? Are you using one of the breakers to feed the 120v side? Thanks, tim
