In wiring aircraft (probably more conservative than wiring
machine tools!) a maximum 1/2 Volt voltage drop is allowed
running down the wire:

wire size max continuous resistance of copper
AWG current Amps ohms
24 4 .03 ohm/ft
22 5 .016
20 7 .01
18 9 .006
16 11 .005
14 14 .003
12 19 .002
10 26 .0012
8 57 .0007
6 76 .0004

so max Length = 1/(2*I*R)

I don't know what your amperage is, but I think each
of your G320's can draw up to 20 Amps....
