ANL fuse
 

what is the biggest i can get ?

200 is the biggest a retailer would sell me... :dunno:

i have 300 amp ones in my car. depends where u go

is the 300 the small fuse or are you thinking about the bigger ones

im thinking an ANL fuse, the bigger ones...thats what an ANL fuse is, if im not mistaking. the biggest ive seen is 300, but i have heard of 400, just never seen em.

did u mean another type of fuse, like the baby anl things?...cuz i think they have a diffrent name, although i am a noob, so i could be 100% wrong

agu is the round ones, anl is the square ish one

baby anl things?...are thay sfa fuse
i think i can get a 300
i'm looking for a 220

^ that'll be 500 amps.

I've seen 750 amp anl fuses

I wouldn't want to draw much more than 200 thru a good compression fit ANL fuse holser, less if it's a screw on the wire type.
You'd be better off to add another fuseholder IMO. Just because a fuse will blow with x amount of current, doesn't neccessarily mean it will pass that current without some resistance.
