The fuse is there to protect the wire from burning up, so you would use a fuse at or just under the wires max current handling. What size wire are you fusing?

 

haha, that's a great point... i love different point of views, they definatly bring a lot of options to the table

 

i'm using 0 guage welders wire to run up to the engine bay

 

200 amp is the max i believe for 0 gauge.... should fixer right up for ya

 

I would say no more than ~300 amps for 0 gauge.

 

No, it's not. It's there to prevent the battery from discharging into the frame and causing fire. You want a fuse on it that will blow if it grounds, and not otherwise. 1/0 can carry a ridiculous amount of current before burning up.

 

ok i'll look into getting one around 200amp

thanks guys

this is a great site
