AC or DC? length of wire? Amperage (load) by the device? continous or intermittent load? Where will the wire run alone or in a bundle of other wires?

Your best bet is find an aircraft mechanic or a copy of FAA's AC43.13A which will give you the information to determine the wire size for either AC or DC circuits.

Wire gauge is determined by CURRENT (Amperes), NOT by voltage!

You would need to provide more information about current, or if you're not sure how to do that, look at the specs on the device. If the power output is rated in WATTS instead of AMPS, divide the amount of WATTS by the VOLTAGE. (120 WATTS at 12 VOLTS = 10 AMPS)

WATTS/VOLTS = AMPS

WATTS/AMPS = VOLTS

AMPS * VOLTS = WATTS
