I'm thinking about an electric car, and a EVCS (charging station). Looking at a 40A unit, but one that plugs in, so requires a 50A circuit since there's no 40A plug defined. As I understand it, this will require 6g power and a 10g ground. I'm also thinking I may run some 12g and install a 20A 110vac receptacle (GFCI) with supply wires in the same conduit. Thinking that THHN wire is called for in a conduit.
Can they share the same ground, or do I need to run a 12g ground wire for the other circuit?
What size conduit would I need for 2-6g, 1-10g, and 2-12g? Or maybe three 12g, if I must run a separate ground for it.
Can I use black for both the power leads, or do they have to be different colors? If different, white for the second, or maybe red? For the 20A circuit, I'd run white, black, and green.
Is there a plastic conduit I could use, or is EMT better (this would be going into a residential garage)?
