Circuit Breaker

[pineranch]

Who has the information and pictures of wiring 40 amp breakers in parallel.
Thanks,
Mike

If you are talking about adding another 40AMP breaker, here is the way I did it on my old SOB.

Its the top 2 breakers.
Notice I used flat bar stock to parallel them together.



The bottom copper bar(on left) is the feed from the battery, so the top left bar just extends the 12V to both breakers. The breakers are marked + on the one side.

Hope this helps.

Or this way.

Just like to add a note: if you can, cover the terminals on the breakers with something non-conductive. Otherwise, if something metallic comes in contact with one of them, you could end up with anything from a dead battery to trailer on fire. I mounted ours inside a metal electrical junction box with a lid. Other options would be several layers of electrical tape.

Great idea Tom S thanks for bringing that up, I do have those rubber covers for the fuses to put on them, but it was this way for the picture so the wires routing could be seen better.
Most RV stores sell the rubber caps so dont forget to get 1 extra when you get the fuse.

Thanks Don! Here's my version (without the cover):

Dealer put in an 80 amp per Lippert. Picked it up today. Battery was a low so the slides still stopped and tripped the CB. Hooked up 110 and all was well. Charging the batteries now.

Isnt that just like a dealer to run the batteries down, they did the same to mine when it went in for some work, then when I tried to bring the RV up high enugh to put it on the truck with a low battery it was dead, I hooked it up to the truck and poped the 30 amp maxie fuse, too much amp draw I guess. I didnt let it charge enugh I guess. just something to remember. I'm glad you got the fuse fixed, did it solve the problem after you charged the battery.
