Re: Best EVSE/charging solution for my situation?

6-3 wire looks like @ $260 vs. 6-2 wire being $160. Is there a decent chance that a future car/EVSE would require the 6-3 wire instead? I don't want to spend money for nothing, but I don't want to kick myself later either.

It seems unlikely that the J-1772 standard will be changed or abandoned anytime soon, so charging stations aren't likely to start using neutral wires. Just remember that to have a normal 240 volt outlet for a dryer or welder or RV connection you should have the neutral wire there. If this will always be for just a charging station you should be ok.

My Daddy taught me, if you're going to take the time to do it, then spend the time doing it right. I would run number 6 wire, and make sure I had all four wires. You never know what the future holds.

My memory may be faulty, so I'll just pose this as a question:
Are more wires used in a socket installation vs hard-wired ?

L2 is two hot and ground only.
If you use a NEMA 14-50 then code requires a neutral that will be unused for an L2 EVSE.

The only exception that I know of is the stock conversion. It uses the neutral so the EVSE runs at 120V but the EVSE's J1772 neutral is connected to the other hot wire through a relay. The only disadvantage it that the unit remains a 12A unit. At 240VAC it is twice as fast as at 120VAC but not as fast as a dedicated L2 30A unit.

If I go with 6-3, is this wire the right stuff? https://www.amazon.com/Southwire-639500 ... s=6-3+wire

I believe so, but wait for one of the electricians here to confirm it.

That will work. Just remember that it is not for use where it may get wet in the course of normal use. If used in conduit, it needs to be large enough that the fill rate is around 50-60% (can't remember what code requires).

What size PVC conduit for the 6-3 wire?
