Mobile Ham Setup Planning (2M/70cm)

10ga wire will handle 100 amps on a 10' run with 12v DC between 10' and 20' it drops to 50 amps if I remember my scales correctly

edit:at up to 300 watts usage

Plenty of wire gauge charts on the net. one down on this page, doesn't really cover the length though, just says increase size with distance. http://www.rowand.net/Shop/Tech/WireCapacityChart.htm

The length is not that far. The engine compartment fuse block to just rear of the driver's side. I would say 6 feet.

Yeah they leave out the part about the ambient temp too, and with it running through the engine comp that may have an effect. Alway best to use half of rated load to stay on the safe side.
