Poll: What 240v Receptacle Do You Have ?

“Nonlocking” was part of a change in the 2014 edition of the National Electrical Code, for which the Report on Comments (PDF) gives the submitter’s explanation on page 70–312: “Locking type receptacles should not be used as they can increase the risk of damage to the receptacle and premise wiring, possibly exposing live parts, if the vehicle were to move while still connected.” Consider that a charging cable could be disconnected electrically, defeating the interlock, but still be connected mechanically or entangled with the vehicle.

 

Locking outlets aren't allowed but hard wiring is fine?

 

Hard wiring what to what?

 

hardwiring the box to the wall wiring, no plug.

 

thanks. it is funny, you can't move the car when plugged in.

 

Yes. You can hardwire the JuiceBox to the wall. This is one of the options offered by JuiceBox at purchase.

 

but what if you drive off with the evse plugged into the car?

 

I don't think you can. The car won't let you drive it when plugged into the wall. And even if you could, you would rip out the plug at the car before you tear the JuiceBox off the wall.

The SAE's J1772 standard will not let you do that. Whether charging or not, the vehicle recognizes that it is attached to an EVSE and will not allow its drive-train to energize.

I can't think of what I might have mentioned that would indicate I actually wanted to increase the time of charging. I've plugged into a 120v 15A circuit while on vacation with the car, and at 8A (in the car) it took forever. It was the only option we had at the time, and it worked. At home, I absolutely don't want the thing plugged in overnight as it is parked outside and a few feet from the street. Don't want anyone getting funny ideas. Too many strange things happen in the neighborhood already at night. A 2 hr. charge is what I had in mind when I ordered the EVSE, and it has worked out beautifully.

The 120v 20A can also serve for the corded power blower, circular saw, and possibly the Toyota-supplied charger cord if need be if the bigger EVSE craps out. When running the power out underneath the porch, it was a cheap option to add.

 

Um, nope, nope, nope!

I have those outlets all over my house and garage some even are grounded.

Besides the 12 amp 220vac limitation they seem to work fine, I am told they are notoriously fragile and short but I’m guessing as long as I don’t plug/unplug a lot and keep an eye on them there shouldn’t be any magic smoke

 

we had those when we moved in here, house built in the 50's.

but with metal boxes and ground wire, it was a pretty easy swap out

 

This is why circuits are protected with breakers or fuses. If the receptacles work, I'd keep using them. If they eventually break, then replace them.

 

I just use 120V. My cousin has a Leaf, and she just plugs in 120V over night. No real reason for hyper fast charging, but the panel in my garage is right where I’d put a 240V charger if we ever buy one, and I’d just hardwire it to some Romex inside a junction box. Easier, cheaper, and cleaner-looking than using a plug.
