Purchased two new bus bars, new grounding bar, bunch of new connectors and a 50 Amp circuit breaker I plan to wire inline from the battery.

Was planning on getting some new battery cables. Wondering if anyone know how much I'd need for the run. 5ft should do it right?

I figure, from battery to busbar 2 AWG and using a 1/0 awg to link the two batteries.

I believe that my AM Solar kit came with 6 awg duplex and I was thinking of running 4awg to the battery from the charge controller.

So add another 5 feet there.

Cool

Today's progress was cleaning up the OE wiring hack job. I have not finished the other portion as I keep adding more things into the mix. Right now I ordered new cable to replace the battery and run from the solar controller to the battery, and also purchased a 50 Amp marine grade circuit breaker from Blue Sea systems on advice of Lewster that once my new cable gets here will go between the battery and the rest of the electrical.

For anyone wondering about the second picture, with my remodel I am placing my solar charge controller and inverter on the back side of the OE panel. I built a cubbie door that I can access those and service them from within the trailer if need be.

More photos as work progresses. I keep starting and stopping to order things.

Also, the two ? marks. I have no idea WTF is going on with these. Airstream's idea of grounding a wire is to butt connect it to a bigger wire. And this black and white wire with a 1 amp fuse in the middle of it. No clue what that's for. But it has to be factory since off into the wall it goes.

And yeah, I snapped the photo before I put the heat gun on the heat shrink and cut my remaining zip ties. Either way, better than before.

I see that 1 amp fuse all the time. Looking how it's wired to the on the positive copper bar side of the positive bus bar and not on the downstream side of the DC circuit breakers, It is probably the LP detector. Pull the fuse and see if the little green light on the detector goes out.

BTW, I'm working on a brandy new '15 27FB Twin and it seems that Airstream has been listening on our comments about wiring! The wiring job, especially in the circuit breaker box, is noticeably neater, but still has a way to go to be fully acceptable.

Also, Parallax has upgraded their DC fuse block that cones with the converter package to include LED failure lights........Just like the ones Progressive Dynamics has been using for years!!

Thumbs up

So revisiting this old thread. Since I just finished my lithium install this weekend, I redid this again, moving it to the back side of it's original place. Gained a few more inches of space in my front storage compartment, and I can access this from inside that airstream if needed.

The Airstream itself is now isolated from the batteries with a 50amp circuit breaker, per an earlier recommendation from Lew.



I used 2 AWG from the house batteries to the Airstream's new bus bars and added an additional ground bar because mine was crowded as it was and increased the solid copper size and added a new bolt under the Airstream for it. Old one was janky.
