Wire gauge sizing
Does anyone know where I can get my hands on a table of wire gauge/amperage data for 12V automotive wiring? Surely there must be an industry standard for this. No redneck engineering allowed 
. Thanks.
. Thanks.

i work a commercial electrical out fit. we size our wire by amperage not voltage, 480 is the largest voltage source i have messed with. the way we do it is. 14gauge is good for 15A, 12gauge 20A, 10 gauge 30A, 8 gauge 40A, 6 gauge 50A,this is for A/C current systems now im not exactly positive but DC current may require larger wire being that current only flows one way. but you can look at your fuse box (in your truck) and see what size fuses correspond with what size wire. meaning what size wire is hooked to a 10A circut, 15A, 20, 30, etc.

Bill,
I did a quick search and found this place, I'm not sure if you'll find your answer but I thought I'd post it any way.

I really wanted to know what the existing wiring was good for before I started adding to it. Some of these items are on the battery saver circuit and I'd lilke to retain that feature on the adders.

Naw, I was going to apply voltage to the cow magnets on my fuel line to improve gas mileage but I scapped the idea .
