I finally decided to get a 240V 50A line run out for my Model S. I've been doing fine on 120V 12A, so this wasn't urgent, but with a Model X on the way for my wife it seemed like a good time to do it.
I got a bid from the EV branch of a local solar company that I _thought_ was reputable, but ended up with an absolute mess of a hacked, incomplete install. Absolutely terribly incompetent. I've fired them and don't ever want them near my electrical (or anyone else's for that matter) again. I shudder to think what shoddy work they've done elsewhere.
Here's what they did:
I moved a couple of other breakers to THQP's further down and put a full sized 50A breaker in the top slot, cut the nicked ends off and restripped the wire, and torqued it all down properly, so I have a functional install. But I'm left with a 6/2 run to a NEMA 14-50 and need to get this inspected. What should I do?

Here's what they did:
- Tried to put a slim THQP breaker in the top slot in my GE panel, which doesn't accept them in the top slots. They then tried to physically modify the breaker and the breaker slot in the panel to make it fit. I rose a living fit when I discovered this and had them put everything back and told them to never call back.
- Ran 6/2 NM-B cable above the drywall in the garage ceiling to a NEMA 14-50 outlet. No neutral wire. Fine for a UMC, but clearly not to code.
- Nicked the living hell out of the conductors when stripping the ends of the cable.

Options:
- Run a new, proper 6/3 cable to the outlet. This will be a major pain and expense to re-run a new cable.
- Run a single 6/1 strand to wire up the neutral. Would this be to code?
- Swap the NEMA 14-50 outlet for a NEMA 6-50. I have a 6-50 adapter for my UMC sitting in the closet, so this would be pretty easy and do the trick. My only concern is it's the older style UMC adapter and not the redesigned, gray plastic center adapter like the new NEMA 14-50 recall replacement adapters.
