Battery disconnect

Looking to install a battery disconnect switch. I was thinking of putting it in the cabinet next to the converter in the trailer. I'm just not sure if switching the ground wire is the way these are typically wired in? If anyone knows that would be great to get input.

Most folks put the cutoff close to the batteries to ensure everything is disconnected. It doesn't really matter if you use pos or neg. I always use negative as it's easier in most cases.

I found a random one off of eBay and installed it in a storage hatch. Wherever you install it, make sure it's easy to get to from the outside and out of the reach of little hands (if they're a concern for you).

I installed one on my 5th wheel. I would like to make a point that I had to think about. there are several leads connected directly to the battery that remain active if the factory installed battery disconnect switch is used to disconnect the batteries. one of these leads is the safety brake switch. it does not drain any power from the batteries but needs to have a 12 volt source to activate the trailer brakes if the trailer separates from the tow vehicle. if you install a disconnect switch that disconnects all circuits from the battery, you need to ensure that the brake emergency switch has power whenever you are towing.

battery disconnect

I also mounted mine on the battery box. I used what's known as a "deep octagon box", nothing special and available at most home improvement stores. I mounted it directly to the battery box, interrupted the HOT cable with the switch. This makes the switch easy to access and when in the OFF position I hang the key on a hook just inside the TT door. I painted the box a "hammer tone black" to give the paint some texture. Works for me

I understand the concept of a battery cut off switch. Would like to know how and when to use it. I have one but have never used it. I take the battery in during winter months storage.
