Length of wire / gauge chart

[IDSkoT 5,000+ posts]

In a recent buy, some of the paperwork had a nice chart with various lengths of wire, the current demand, and then what size wire you need...

So... here it goes:

0-4ft:

0-20 Amps: 14-AWG

20-35 Amps: 12-AWG

35-50 Amps: 10-AWG

50-60 Amps: 8-AWG

65-85 Amps: 6-AWG

85-105 Amps: 6-AWG

105-125 Amps: 4-AWG

125-150 Amps: 2-AWG

4-7ft:

0-20 Amps: 12-AWG

20-35 Amps: 10-AWG

35-50 Amps: 8-AWG

50-60 Amps: 8-AWG

65-85 Amps: 6-AWG

85-105 Amps: 6-AWG

105-125 Amps: 4-AWG

125-150 Amps: 2-AWG

7-10ft:

0-20 Amps: 12-AWG

20-35 Amps: 8-AWG

35-50 Amps: 8-AWG

50-60 Amps: 6-AWG

65-85 Amps: 4-AWG

85-105 Amps: 4-AWG

105-125 Amps: 4-AWG

125-150 Amps: 2-AWG

10-13ft:

0-20 Amps: 10-AWG

20-35 Amps: 8-AWG

35-50 Amps: 6-AWG

50-60 Amps: 4-AWG

65-85 Amps: 4-AWG

85-105 Amps: 2-AWG

105-125 Amps: 2-AWG

125-150 Amps: 2-AWG

13-16ft:

0-20 Amps: 10-AWG

20-35 Amps: 6-AWG

35-50 Amps: 6-AWG

50-60 Amps: 4-AWG

65-85 Amps: 2-AWG

85-105 Amps: 2-AWG

105-125 Amps: 2-AWG

125-150 Amps: 0-AWG

16-19ft:

0-20 Amps: 8-AWG

20-35 Amps: 6-AWG

35-50 Amps: 4-AWG

50-60 Amps: 4-AWG

65-85 Amps: 2-AWG

85-105 Amps: 2-AWG

105-125 Amps: 0-AWG

125-150 Amps: 0-AWG

19-22ft:

0-20 Amps: 8-AWG

20-35 Amps: 6-AWG

35-50 Amps: 4-AWG

50-60 Amps: 4-AWG

65-85 Amps: 2-AWG

85-105 Amps: 2-AWG

105-125 Amps: 0-AWG

125-150 Amps:0-AWG

22-28ft:

0-20 Amps: 8-AWG

20-35 Amps: 4-AWG

35-50 Amps: 4-AWG

50-60 Amps: 2-AWG

65-85 Amps: 0-AWG

85-105 Amps: 0-AWG

105-125 Amps: 0-AWG

125-150 Amps: 0-AWG

It didn't have for anything bigger than 150-Amps.

I'd assume 0-AWG for 150+ amps.

And for those of you who don't know, to figure out the current demand, simply add up the amperage of your fuses on your amps.

This is a nice reference for those kids just starting out, or if you're just confused.

(And if you're wondering, this is from a Zapco amp's Owner's Manual)

EDIT:: For those of you who don't know, 0-AWG is the same as 0/1 gauge.

I still think this should be stickied.

IMO if we are trying to get a wire sizing chart stickied we should make an image with colors and graphs or charts of some sort. Just would draw much more attention.

looks to be on the side of overkill to me.

I like bcae1's chart the best. It doesn't just throw out random numbers and expect people to accept it as gospel. It explains HOW the numbers were derived (no more than 1/2v drop) which I think is good to know.
