I had an inline fuse on my battery, but I blew it recently and didn't have a replacement. Since I wasn't near home I just pulled the fuse and pushed the wire through to meet in the middle of the fuse holder. I'd like to run a breaker instead, so I don't have to worry about replacing fuses any more. Anybody running one? Where's a good place to get one? I looked at Jeg's but they only have a 30A breaker, and I couldn't find one with a pic at summit racing, so I don't know if they have what I want.
Basically I just want to fuse the positive terminal from the battery in the back, I would think it needs to be rated for 80 Amps or so.

Be sure you get a breaker made for DC :p

May want to look into the boating world... a lot of higher-end boats are using breaker boxes and stuff for their shore-power connections, and afaik, boats are primarily 12v with an inverter operating certain AC stuff. But, they are likely to have decent sized DC breakers.

I don't think your starter pulls anythign near to 200Amps does it?? Thats a ****-ton of power. What gauge wire are you running,a nd what is the max amperage that can go through them? figure that out,t hen buy a breaker that has a limit that is less than your current carrying capacity of the smallest dam wire in your system. i think 60Amp s probably going to be about right.

There are a few of those with different current ratings, I don't think I would get the 200Amp one anyway. I'm worried about the wire shorting out on something, as a safety issue, not all the other fused stuff. I think if the positive cable were to short on the car it would trip a 200A breaker. I know it did once with the fuse I had, which was rated 60A at 32V (so 160A at 12V).

I'm running 2ga wire from the cargo box to under the dash, then sit splits into 2 4ga wires, one to the starter and the other to the fuse box.
