Is this a L2 charging outlet already in my house?

So I'm buying a Volt in the next week or two, and I'm checking my garage to see where I'll plug in. This house is a rental, so I can't install a permanent charger here as we will be buying a place in the next 1-2 years.
Anyway, I have the standard garage outlets, but there is another weird one. It's just one outlet, not a double outlet like most. And it is not recessed into the wall. It's got a normal grounding slot on the bottom, a sideways T on the left, and then a horizontal slot on the right. Is this a 240v outlet that I could use to charge faster? I know absolutely nothing about electrical stuff, so I don't even know where to begin looking to find out. I took a pic of it, but it's too big a file, so I'll post it from Photobucket here in a bit.

if it looks like this, it's a 6-20. It's a 20 amp 220 plug. Common for window heater/ac units.

You'll just need an EVSE with adapter to 6-20 or one already equipped with the 6-20 plug.
L2 Charging outlet

Sounds like a NEMA 6-20 outlet. 240 volt, 20 amp. Check the chart on the following link to be sure.

Lucky you, that's 240V and 20A - just enough for a Volt. :)

Yep, that sure sounds like a 6-20 outlet, which can also handle a 6-15 plug.



If you're getting a 2016-17 Volt, the EVSE can be plugged into it, using an adapter for Level 2.

If you're getting a 2014-15 Volt that has an EVSE with part number 2296 7199 (visible on the side), you can plug it into that outlet using an L2 adapter, and cut your charge time down to ~4 hours.

If you're getting a 2013-14 Volt that has six screws, holding it together in the back, the EVSE can be converted to use it as Level 2.

If you're getting a 2011-12 Volt, those EVSEs can't be modified nor can they use adapters for that outlet.

Check to see if there's a 20a double pole breaker in the panel. Presumably, they used the outlet for a window AC unit. That's the most common use for that type of outlet.

That's exactly what it looks loke to me. Awesome!

There are a few double breakers in the box. Most are standard stuff-- oven, laundry, condenser, but one is labeled "load control". No clue what that is. The outlet in the garage is on a inside wall, so no windows. The other side of the wall is just the foyer of the house, so Should I stay safe and just have an electrician come to the house to check and make sure this outlet is good before I plug it in to charge my car and end up potentially fry something or burn the house down?
It's real easy to test if you have a meter. The two main prongs should provide 220-240VAC, going between either of the prongs to the ground prong should give 110-120VAC. If that checks out, it's a good plug. Next would be to go to the breaker box and turning each one off to see if it cuts power to that plug. Even if it cuts to the plug, make sure it doesn't cut to something else as well. This will verify that it's on it's own circuit. It will also allow you to label the breaker that goes to that plug.
Jasony0423 If you don't already know what the outlet is, or how it's wired, PLEASE have an electrician check it before you use it.
Burning down your new rental isn't going to win you friends and, unfortunately, I've seen a lot of really screwball electrical runs.

I really, really "second" this advice!

If it wasn't clear, you can't plug your Volt directly into this outlet. You need a charging station. Now, there are hacks that can be done to the 120-volt cord (not a station that mounts to the wall, but a cord) that comes with the Volt to make it charge at 220-240 volts. Doing so will void your warranty. Also, the voluntary NEC (National Electric Code) rules ask that 220V chargers be wall mounted and not merely cords, but that compliance is voluntary.

Check out online 220V PLUG IN chargers. You'll find models with various plugs. When your electrician is there, show them to him and get his advice. He may need to change that plug to a different configuration even if there's enough juice and looks okay otherwise. This is no big deal.

Good luck and congratulations on having 220V already installed!

Ditto this. A licensed electrician will not cost that much to check it out. Knowing that it is good (or not good) is priceless.

I must have missed that memo! I thought it was only 2016+
Unfortunately, my EVSE is 2294 :(

Then that one is a 2013-14 Clipper Creek version that can be converted to do L1/L2.

Yeah, not worth the hassle. I have dedicated L2 at home. Might have rewired at the cottage if L2 was just an adapter away, but L1 works for now as-is.
