Battery Disconnect Switch
When would you switch the disconnect switch to off? I don't really understand the purpose of the thing.

PS, they are NOT meant to be OFF when using or transporting the RV. There is NOTHING bad that will happen by having the 12 volts ON. If your Battery disconnect is OFF, on a towable, then your break a way for your trailer brakes will not function.
I thought on most trailers the breakaway brake system was wired directly to the battery, bypassing the disconnect switch (and often unfused). Legally I'm not sure if the federal vehicle standards permit it to be switched. From a battery drain standpoint, of course, it's rather a moot point because it consumes no power unless activated.
I don't doubt that a few breakaway brake systems may be (incorrectly) connected through the trailer electrical system disconnect switch.
My comment was meant for those that want the battery completely disconnected. I doubt there is a Federal code for HOW 12 volts is supplied to the Break-a- way system. It is assumed that there will be power when on the road. It is BEST to have the battery Break-a-way wired directly to the battery. Doug
