Rv Battery Disconnect Switch Installation Positive Or Negative

The switch is rated at a steady amp and a momentary amp.

Rv battery disconnect switch installation positive or negative. This essentially adds a on off switch to the positive line going from the battery to the camper so when turned to off the camper devices do not continue to draw from the battery. In case your rv does not have one you can opt for an aftermarket rv battery disconnect switch installation. 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 the geometry of the situation forces you to put it on the positive terminal that works just as well.

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. I plan on installing a battery disconnect switch on our bc this spring when i bring it out of storage. I did install a disconnect switch on the house battery negative terminal and will probably do the same on the chassis batteries. Typically the battery disconnect switch is designed to disconnect the house batteries similar to pulling the negative cable off the battery so nothing can drain it when the unit is not in use or in storage.

Thus less amps on the switch. 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. Just be careful when making any connections to house batteries. To provide more specific troubleshooting information we need to know the make model and year of your rv.

To answer your questions. It s the same principle as why you should always disconnect the battery s negative side first. My first inclination was to put the switch on the negative leg of the circuit. The negative cable connects to the body ground already so there s no additional danger if it rubs.

I say negative and heres why. The switch disconnects the battery s electrical power or isolates from the house portion of your rv. 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. It s a class c mh so no 5er or tt issues.

Spotting the switch in the rv is quite easy. 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. 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.
