Rv Battery Disconnect Switch Installation Positive Or Negative

I say negative and heres why.

Rv battery disconnect switch installation positive or negative.

To provide more specific troubleshooting information we need to know the make model and year of your rv. The switch disconnects the battery s electrical power or isolates from the house portion of your rv. As i was considering this it came to mind that somewhere i had read and or heard that the switch in this type of circuit should be on the positive side. If your battery bank is floating not tied to any sort of safety frame ground in theory you want a double pole switch that turns off both and power at the same time.

If your system has the battery negative tied to earth safety ground or frame ground of a vehicle then you want the switch in the positive leg. I plan on installing a battery disconnect switch on our bc this spring when i bring it out of storage. Thus less amps on the switch. If the geometry of the situation forces you to put it on the positive terminal that works just as well.

To answer your questions. There s a more practical reason the negative post is more accessible and it doesn t have the extra hot wires going to the positive battery clamp to deal with. Just be careful when making any connections to house batteries. It s the same principle as why you should always disconnect the battery s negative side first.

Spotting the switch in the rv is quite easy. To wrap it up usually the best place to install a battery disconnect switch is at the negative battery terminal where it connects to the chassis. I did install a disconnect switch on the house battery negative terminal and will probably do the same on the chassis batteries. The battery system has the bim battery isolation manager on a separate fuse and relay panel.

It s a class c mh so no 5er or tt issues. In case your rv does not have one you can opt for an aftermarket rv battery disconnect switch installation. So you re less likely to have the shower of sparks when disconnecting the switch since you re further away from the fender well sheet metal. My first inclination was to put the switch on the negative leg of the circuit.

The switch is rated at a steady amp and a momentary amp. Well if the electrons are flowing from the positive to the negative and some are getting used up by the starter and or the system so there should be less going back into the battery. For our application yes the positive terminal of the battery was connected to the disconnect switch and then the camper positive was also connected to the other pole.
