Re: viair wire guage
I would say 10 gauge.
You might try Viair's website to be sure.

Re: viair wire guage
Keep in mind that the gauge of wire used should be determined by the distance that the compressor is from the power source.
If your compressor is mounted near the battery it will require a smaller gauge wire than if it's mounted on opposite ends of the vehicle. To small a power wire could lead to fatigue in the compressor as well as potential for overheating the source wire.
