eithernet cable is pretty thin ie, about 23 awg, but if they are using low amps, it may not matter.
unless they have old thin cable whic still a thin 20awg.
thicknet runs a heft 12awg
I used 10 and 12 because 1, it was tomy track and 2 we race 6 mag unlimited cars.
I figured I had a good setup when some of the top racers hit my track and asked if I was running 20volts or more. They were surprised I was at 18volts.
But I also had 68amps
