what gauge is the ARB air compressor power wire?

Finally getting around to installing compressor but what I thought was a 10 gauge wire is larger. Home Depot doesn't have any 6 or 8 so Im trying to figure out the gauge so I can order terminals from Amazon. Unless anyone knows anywhere else I can look. I have the dual but I think its the same as the single.

 

did you ever get this question answered?

 

Just measure the core thickness and look it up.

 

Was looking for the same info today ... Here's what I found in the manual (found here: https://www.4wd.com/sku/ARB 4x4 Accessories/standard/CKMTA12.pdf) (Arb Dual Compressor CKMTA 12/24):
Page: 16 -
"Crimp suitable gage automotive eye terminals (not supplied) onto each of the heavy gage (5mm2 [10 AWG] RED wires."
"Crimp suitable gage automotive eye terminals (not supplied) onto the heavy gage (8mm2 [8 AWG] BLACK wire that is marked with a white stripe (BLK-WHT)."

Hope this helps.
