Ahaaa..... as always thanks for the inputs
Erasmo, that warm cable was the 14 gauge zero supplied cable. I was surprised myself since it wasn't even charging from very low SOC.
Usually only the ends get warmish... maybe the little electrons had a party in there this time
Everybody else, yes, I agree, 16 gauge coiled up will make my coil melt in the long run.
And also MrDude1, you're right, while my Cat is charging, there is no escaping through that garage door anymore
I'll look into simply running an extra conduit with gauge 10 or 12 wires like I run for most machines in the shop and be done with it on 240 V.
Although, I got to look into this once more. I know dryers and stoves run tab to tab 240 like it comes from the pole, but that is technically two phase power.
I am only used to dealing with three phase and single phase (120V to neutral)
So the zero is usually taking one hot leg from the 240 incoming and returning on neutral like every other load in the house.
When you're using tab to tab, you then use the full potential that comes from the pole, but that now is 60 Hz 120 VAC on each leg.
Wouldn't that make it two phase 240.
Got to read a book about that real quick again.
Don't want to fry my Cat
