turning off 7345 converter

I read somewhere on rv.net about installing a switch to turn off converter so that you plug shore cable directly into an inverter. I was wondering what wire that would be or if I could just flip a circuit breaker. My battery bank is in my trailer and the TC battery is just for emergency use. Or is it as simple a just disconecting the TC battery?

    It depends on the coach, on my house on wheels, it is a breaker marked CONV, On some it is also the bathroom or the bedroom or the fridge circuit.. All depends on how it's wired..

    The 7345 being a power center and converter in one.. I suspect it will be like mine.

    Before I turn the inverter on I flip the breakers for two ACs, the microwave and the converter/refrigerator.
    I have an automatic transfer switch that switches the inverter to the service panel when it sees power from the inverter.

    You can download wiring diagrams for your rig HERE to see how they wired yours.


    Thanks for the link, but my unit is a 2006 made bh AMLRV and not the Winnebago adventurer camper.

    Is the inverter wired to the trailer batts for its input? No feedback with converter on TC batt unless the trailer batts are jumpered to the TC batt to get at the DC dist panel in the camper. Anyway the converter will still come on in the camper and run the 12v stuff instead of the batteries.

    Take the cover off the 120v circuit breakers and you see black wires going to them underneath. The converter is down below so you can see the black wire from it coming up to a breaker. Don't do anything with the white wire. the black wire may be spliced in with the black wire for another circuit often the receptacles.

    Snip the black wire from where it is on the receptacles circuit and tape the end still on the breaker (or it will short on the metal cover when you put that back on) Now you have choices.

    You can splice that black wire over onto a different circuit like the air conditioner you won't be using when on inverter. But then on shore power, you might not be able to run that and the converter off that one circuit.

    You can give that converter black wire its own breaker if there is a spare slot. Or you can insert a switch by adding some extra black wires and then re-attach to the breaker it was on before.

    With the switch, you can turn that off and leave the breaker on so the receptacles still work when you are on inverter.

    Disconnecting from the TC battery will not turn off the converter, just make one less thing for the converter to do when the inverter comes on.


    Thanks, I wil, go and have a look at this as soon as the rain stops.

  • My 7345 was wired into only circuit for outlets. A short wire came out of breaker then was combined with hot wire for converter and another with a wire nut. I added a dual circuit breaker in place of a single. Then ran converter wire to other side of new breaker. I think breaker was br1515

    My original CONVERTER/CHARGER unit was wired to a 15AMP Circuit breaker in the Power Distribution Panel. My later replacement converter/charger came with its own 120VAC cable and plug so I installed it closer to the battery bank and wired in a new 120VAC Receptacle which was on its own circuit breaker. I just flip the 120VAC circuit breaker to turn the converter/charger units OFF.
