Another Big 3 Thread....

Okay guys I know you all are tired of this. I read through like 10+ threads before making this because I am tired //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif ... I am going to be upgrading the big three for my 200A H/o alt... I am wondering if 4 ga. will be ok and also if fusing 4 ga. wire with 250 ANL fuses is too much (melt wires). I believe I read that it is a little much since 1/0 uses 200-300... I will be using 250's for my 2 awg. to the amps but Please advise on the wiring for the big three and what size fuse. As of right now I was going to use 4 gauge wire with a 250anl fuse.

The amount of current a wire can handle is dependant on thickness and length.

The amount of fusing required is dependant on the amount of current the wire can handle.

Amperes means the "fuse size" ??

Your a nice guy and all but you ask some pretty silly questions.,

example- a fuse can be rated for 30 amps.
