    That certainly is good advice but if the battery terminals are disconnected even the breakaway won't work.

    Of course, but that's not what I said. Rather, anyone choosing to use a battery disconnect switch to prevent unintended draw down on the battery while the trailer is not being used would be well advised to wire the brake system breakaway switch directly to the battery and not through the switch.

    Where does the disconnect go on an arc reactor battery?

    Lol, in home systems , a neutral, white wire is just another ground wire. I say the same all the time. No biggie. Unless you dont know what a neutral is [:D]

    The white is usually connected to the ground bus but not always. You should never use the ground as a neutral. Just nit picking:)

    In a 120 vac system sure but we're talking 12 vdc in a camper where the negative of +/- 12 vdc is connected to the negative terminal of the battery which in turn is connected to the trailer frame and thus is considered ground.

    No problem there. I was addressing this statement "Lol, in home systems , a neutral, white wire is just another ground wire."

    No it's not. In 120VAC, the neutral carries current back to the source, and remains hot during normal operation. The ground, is just that, a ground, and doesn't remain hot during normal operation, only if there is a fault. Please be careful doing any electrical work :)

    In the older systems , they are conected to the same ground bar. In essance there the same. Newer stuff now has to be issolated more. Years ago they had no grounds. Then after that the bx jackets provided ground ( stull no wire) then they adding in a undersized wire for ground. Along the way they made romex like the wiring we know today. A white wire( neutral) is the current returing to ground. It takes the path of least resistance, thus back to the circuit rather then to earth ground. If it breakes the power will still work ,just using the back up ground wire. Thanks for the concern about the wiring, but i think im ok with it!

    There should be no case where the ground wire carries current. If the neutral is broken the circuit is open. The ground should only be connected to the case if the case is conductive.

    Beating this residential 120v horse a little more, only in the main electrical panel are the ground bar and the neutral bar connected by the bonding screw. All sub-panels should have separate ground bars and neutral bars, with appropriate wire feeding back to the main panel.

    Older homes didnt have seprate ground and neutral bars, they only had a ground bar. Going back farther, to knob and tube there was no ground , just like the older bx , they added the ground later as a saftey in case the neutral broke. It is basicly a fail safe for the neutral, or another way for the ellecteic to go to ground.

    Ground also protects against overloaded circuits, such as a lightning strike
