Wiring
Last night we talked about wiring. There are two wire gauge standards.
AWG = American Wire Gauge - vehicles
SWG = Standard Wire Gauge - often used for marine service.
AWG is usually used for vehicles and it is smaller in diameter for the same gauge than SWG.
I usually use 2 conductor marine SWG, which is available in its own plastic conduit and best of all the cooper wires are tinned to prevent internal corrosion from high humidity marine environments. There is roughly a two gauge difference between SWG and AWG the the same wire diameter.
Wire Gauge / Wire Gage Conversion Chart from READE
I use the following marine wiring guide, based on AWG gauge. So for a voltage drop of not more than 3% and 20' wiring run, including ground return drawing 30 amps at 12 volts, you need 6 gauge AWG or 8 gauge SWG. I am not sure what the Puma draws, but as the tire pressure increases so does the demands on the motor and power used. Going to smaller diameter wire you will experience a larger voltage drop and more waste heat due to the increased wire resistance.
I also have a 24-volt chart. Generally the higher the voltage the more carrying capacity of the wire.

The Puma will draw 50A.
I wired mine with 6 awg marine wire, a blue sea 60A maxi fuse holder, and 120 amp Anderson powerpoles.

It's a kickass compressor and a real bargain afaic.
