[QUOTE="Rashaddd, post: 5434979, member: 592162"] Doesn't matter though, as for the same reason the fuse won't blow instantly, no electrical component will. They all have added tolerance over the amount of power they can handle "all day", and no amp that should be fused at 250 amps will blow from a momentary 260...
