220V dryer socket

Mon Aug 23, 2010 8:54 pm

My $3500 AV quote is too high. The main reason for that is the 100 ft. wire/conduit run through the attic from my main panel. But I have an unused 220V clothes dryer socket already in the garage. It's not on the wall I would like, but I am willing to use that side if it saves big bucks. All this talk about AV, Blink and Leviton has my head spinning. Does anyone have a clear answer as to whether an existing 220V socket (from some time in the 1950's or 1960s, probably) can be used with any Lev. 2 EVSE? If it makes a difference, the existing wiring is Romex, not in a conduit. I don't know what current code is or whether a permit is needed for all of the EVSE's. I don't care whether I can get maximum current through it, as my alternative is Lev. 1 only. Is this something only an electrician can determine for sure? I understand they would all need to modify the socket itself to put in the hard-wired portion, so my question really goes to the wiring, I suppose, i.e. avoiding the 100' conduit run.

The breaker is a double-width (2 slot?) type marked 30 on both.

yes, most dryers are 30A 240V, so you might just need to change the outlet to a 6-30R,
you can use the middle of the road Leviton (draws up to 24AMPs from the 30A circuit)

You will be able to plug in the Leviton there, or you can "extend" that circuit from that point to wherever you need it, with a piece of 10-2 romex, or a conduit.

The 2011 Leaf is only comming with a 3.3KW charger intitially anyway, so you will be fine.

The 30a dryer connector, wiring, breaker will be fine.
I would just get a EVSE to cover the 3.3kw needed.
You can hardwire the EVSE or change the connector to what is needed to match the plug on the unit.

The key thing to remember is that you cannot either install or plug in an EVSE like AV's which is rated for 30A or 32A. Your limit will be 80% of 30A, which is 24A. The electrician was quite correct if he told you that you could not use that circuit for the AV charging dock.

THe Leviton EVSE uses NEMA 6-50R plug, they are available at home depot for about $8, these are the same plugs used often with welders. I now have three of these outlets installed in my garage on separate circuits. One I used for a mig welder for EV fabrication, one for charging and the new third location I installed at the nose of the car for the EVSE with 1" conduit. My cost to do this was about $100. The best part is AV say this, noted it and took pictures of it and quoted $2450. Even the wire was looped outside the conduit waiting for the EVSE to be attached, could not be easier for them unless I did it myself.

Evdriver, there are 3 different model Leviton EVSEs, each uses a different plug, from the smallest which uses a 6-20R, to the middle model which uses a 6-30R, to the largest model which uses a 6-50R

I believe that the AV L2 EVSE does not require a 40-amp circuit, but I am not sure.

Call AV, and see if the internal "max-current" Control Pilot can be set at 24 amps for use when hardwired to a 30a circuit, or even 16a for use when hardwired to a 20a circuit.
