Bussbar/circuit panel for medium sized 12v loads?

[justinm001]

My 12v bay was feeling neglected so started on rearranging them. Actually managed to fit 2 air compressors in saving a ton of space in another bay.

I ordered a couple 200a mrbf fuses and blocks to connect the batteries to the Lynx. I'm thinking of adding that little breaker for my small loads but it's limited to 20a and 100a total. I have a few of these scattered around the coach. Is there any recommendations of a distribution block/bussbar thatll easily allow me to connect a few 100a or so loads to the Lynx? I could get a 2nd lynx but they're so large, would like an 8 port lynx that's more 500a.

The way you have the fuses setup on the bussbar, appears you are amplifying the fuse capacity into the second bar.

Yeah that's kinda my problem. They're 4ga 100a to sub panels and I used a 100a fuse. It's all small loads and I think the largest load is 40a for sirens and lights. Everything else is just a couple amps, cerbogx, relays, phone chargers.

Am I correct in thinking it's OK to stack 4ga wires to 100a fuse even though they go to multiple loads, as long as all the loads combined are under 100a? It might be best to just get a 2nd lynx and run dual 4ga wires like on the 2nd bar.

Actually I think that 2nd 4ga cable is to my mppt which is only 30a.

No, i mean the way the fuses are arranged, none of them will work.
The largest fuse is on the same buss as the smallest fuse, none will fail...

OHHH No it just looks like that from the photo. Here's a stock photo of the Lynx. The black/neg is below the stud mounts for the fuses where the wire lugs connect to.

That makes more sense!

Where did you mount the MRBF fuses? Are they slow blow or quick? I'm trying to figure out how to wire the new Lifepo4 batteries that will also need to start the on board Onan 5500 generator.

They just came in and actually just added them between battery and lynx. I have another lynx coming tomorrow and once that comes ill cut the 4/0 wire and hopefully have enough so I can wire both batteries into the lugs so they have their own fuse and more amps.

I used these mrbf

I have others under the lynx for the DC DC converters and they must be slow burn. I believe mrbf are like class T and better than other fuses as less chance of arcing shut.

I've had issues with the mega fuses in lynx and I swear they don't work. Have had a couple melt a bit but none blow before.
