Fuse Block-is it safe?
i'm going to assume that like most all modern automotive applications, the JK utilizes a negative ground system (it's next to impossible that it doesn't). if that's true, u would want to secure it. if u don't and it moves around and one or both of the terminal posts contacts the body (or another piece of metal which is bonded to the body somehow) a direct short will be formed. this will create a high current draw which means a good bit of heat (possibly a fire). it's also possible that your battery could explode as a result of a direct short. if anything it would create a draw on your battery, draining it quickly. i'd definitely recommend securing it to something. you may also want to wrap some tape or put some heat shrink over those posts. it just lessens the chance of hitting them with a wrench or something while working under the hood
Thanks for the advice. I have a "boot" to cover the circuit breaker- but it wouldn't fit with the big cables- I'll make it work. The Fuse block is secure and I'm taking everyones advice and securing the circuit breaker to the firewall. Joe
That's fine...just be sure your total load to the box is no more than 30A. If you need more circuits then you will have to up the breaker on the positive lead to the battery up to a max of 125A (I think is what the instructions say) although the box itself handles 100A of load. Depending on the application, I have found that liquid plasti-coat electric tape holds up well for coating things like exposed screw terminals on large fuses and battery cables, etc. as a barrier to metal tools when tinkering nearby.
