Reddit mentions of Blue Sea Systems Common 150A 10-Gang BusBar with Cover

Here’s my write up on JeepForum

This is the fuse block I used

I used 6-position covered terminal blocks similar to these, although I got them for $3/ea at a local store

This was my ground bus bar. it was cheaper when I bought it, and 10-position is nice but I probably could’ve gotten away with less

These are the waterproof sealed relays I would recommend

This is the circuit breaker I wish I used, but I had the 150A on hand. I’ll probably swap it out at some point

Edit: to add on, I used heatshrink on noninsulated female disconnects so that I could have everything properly color coordinated for easier work if I needed to make repairs/modifications in the future. I only used 1/4” Red/Yellow/Black HS on the board :)

EDIT 2: I used the wrong link for my writeup. It's fixed now!

First, my needs:

1. Power 1/2 LED monitors at ~30W each
   
2. Occasionally charge laptop
   
3. LED lighting
   
4. 2 Maxxair fans

   I know my needs are fairly minimal. I see opportunity to grow with this system if I ever need to. I’m excited to lay it out with the actual parts soon and begin thinking about it in the real world.
   
   Any suggestions, info or questions are completely welcome. I know little about electrical, only what I’ve learned from reddit and youtube. Thanks pals and again /u/StolidSentinel for the help and replies to all my messages and questions!

Also... get bus bars... you'll need at least 2... (NEG and POS.. duh) these make your life so much easier when you are hooking 10 things to a single ground, for example... https://www.amazon.com/Blue-Sea-Systems-Common-Busbar/dp/B0091VHLW4/

because I wasn't sure of the term haha.

A bus bar would be perfect. Now I just need to find a cheap one that has a cover; though I could print one if need be.

this is pretty nice for the price http://www.amazon.com/Blue-Sea-Systems-Common-Busbar/dp/B0091VHLW4/ref=sr_1_7?ie=UTF8&qid=1408979981&sr=8-7&keywords=terminal+bus+bar

Which wires specifically? In general, I was planning on going for heat-shrink solder terminal connectors and crimp connectors.

One of the reasons I posted this is because there are quite a few connectors and I am still not entirely 100% sure what I need. Obviously when screwing something in to a screw terminal block, the ring crimp connectors. But when joining wires, I would prefer to use the heat-shrink-solder type, but there are also butts and blades (heh).

I bought this set of terminals, figured I'd need them anyways: Assorted crimp terminals

I am probably going to buy this set of solder terminals: Fancy solder terminals

I am pretty good at soldering (though usually circuit boards, not automotive wires, hence not entirely knowing what to do.) I have easy access to a heat gun as well.

Well, both - the breaker goes on the battery, and it sets the maximum amperage for the entire new fuse block and everything attached to it. The fuses go for each individual circuit. I want to use just one fuse for each circuit, instead of having several different circuits sitting on the same fuse, largely for my own desire for neatness and debug-ability. I could have one main fuse instead of the main breaker, but I figure that they will serve the same function and I may as well go for the re-usable option.

I was going to go for this breaker: Fat breaker

That said, I bought this fuse kit, which includes up to a 35A fuse, which will be more than enough. I also bought this fuse holder, in case I decide to use one main fuse instead of one main breaker. (I figured I'd need both of these anyways for some project, may as well get them even if I don't use them right now.)

In-line Fuse Holder

---

In general, I think my system will basically look like this:

Battery 12V + Breaker = safe 12V

Save 12V + ignition 12V (do I need a fuse here?) + Relay = ignition-switched 12V

Ignition-hot 12V + Fuse Block + ATC/ATO Fuses = eight fused circuits

Fused circuits, obviously, feeding from above. I will probably add a 20A switch in line with high-power circuits, just in case, as an emergency switch.

Fused circuits will terminate at something like this Ground Bar.

 

What do you think of this proposed setup?

I do realize that it's kind of overkill for what I want.

But you can probably agree that overkill is better than your car burning down!
