curcuit breaker or fuse block?
Which do you use coming off of your main battery?
I've decided to switch to a 250 amp curcuit breaker instead of a fuse.
Mainly because I've been using Maxifuses and maxifuse blocks and they seem to come loose after a good pounding..Shoulda got an anl block i know..
Do I NEED anymore fuses/breakers other than the breaker at the battery and the fuses in the amps? I've been using fused dist. blocks after the battery fuse/before the stiff. caps, but I want to switch to nonfused.All the fused blocks I have are maxifuse blocks
So..should each amp get fused from a dist block up to the amps fuse limit? eg...90amp fuse for a 3x30 fuse amp? Or can I skip it?
Do I need to get some anl blocks to help with the loose fuses?
Opinions on the breaker only idea?

I am more of a fuse fan these days though a breaker is a sweet easy to use device.
As far as how many fuses and where they should be located... there should be a fuse for your stereo at every power source (in your case the large fuse by the battery), there should be a fuse to each individual load (if your using 30A fuses try AGU fuses they are small inexpensive and look good to boot).
The point of a fuse is two fold; first to limit damage to a faulty load (say an amp with a short) and second to protect the power supply from the deranged load (thus preventing damage to other electrical devices in the car due to voltage and current fluctuations)

Great article John, soo many things I've done wrong in the past....lol.. That covered everything I wanted to know.
Thanks, I'll be reading that a few times!!
Don't know CoreyC - but I can imagine!! Melted battery/engine bay?
Guess I'll run the breaker under the hood( i bought it already anyhow)
and leave the rest as it was until I get some AGU or ANL blocks.
Heck maybe I can "tighten" the clips for the maxifuses for now.
Cheers guys
