How do I tell if it's a 10-30 or 14-30?

Where is the main panel? I would focus on pulling a new 30 amp circuit to the location you need.
Probably less than you think. After a year of charging you will be so much happier you did it right.
40 amp or 50 amp circuit would only be marginally more expensive although probably unneeded.

10-30 has three legs. 14-30 has four legs. Also should be printed right on the face of the connector.

There's a couple of maybe's on that. If it's a 10-30, then code prevents you from installing a new 10-30 receptacle. If it's a 14-30, you could do it, but you'd need a transfer switch so that the dryer and the car couldn't load the circuit at the same time.


The receptacle is a 10-30. This means I will have to run a new circuit?

I'm not an electrician, but I'm pretty sure that on most residential electrical panels the neutral and ground are on a common bus. As long as nothing else is on that breaker circuit, it should be OK. Having said that, check with an electrician and check with your insurance company.

FYI, the Zencar EVSE uses two hots and a ground, which is typical of L2 EVSEs.

The Dryer Buddy product line I mentioned before has a model with two receptacles - a 10-30R for your dryer and a 14-50R for the EVSE:

It also has a transfer switch, which ensures that the dryer and EVSE can't be run at the same time.

For the Zencar EVSE, you can order it with a 14-50 plug and have them set the highest amperage output preset to 24A. That way, the EVSE will never pull more than 24A.

I am thinking that maybe the most cost effective way to do this would be to install the correct outlet on the garage wall at the same spot that the dryer outlet is on the laundry room side of the garage.


It never fails. Someone asks for an inexpensive solution and people start suggesting a whole new 50 amp circuit. You know, just to "future proof" the setup. I don't know the answer to the last question, but what about leaving the dryer outlet as-is and running another length of 10-30 from it, to a box with the EVSE hardwired into it in the garage? Then the main concern is not running the dryer and EVSE at once.

I think the main concern with a 10-30 receptacle is that there is no true ground - it's really just meant for electric dryers with a bonding jumper. Even with the Dryer Buddy device, they are still going from 4 wire to 3 wire so I don't know how they deal with grounding - I'm guessing they don't. If there was ever a fire caused by using an EVSE on this dryer receptacle, it's likely insurance wouldn't cover it.

For that reason alone, I personally wouldn't use a 10-30 receptacle but the OP is looking for an inexpensive solution. It would be safer to pull new cable and put in a 14-30 or 14-50 receptacle.

I am due to get my used 2014 SL on Friday. I don't think I am going to be able to live with Level 1 charging, so I'm trying to figure out a Level 2 solution that won't break the bank. I have a 22x22 foot garage that shares a wall with the dryer outlet of my laundry room. I may have the Leaf in the garage sometimes, but most of the time it will be in the driveway just outside of the garage.

I am thinking that maybe the most cost effective way to do this would be to install the correct outlet on the garage wall at the same spot that the dryer outlet is on the laundry room side of the garage. I am thinking this would require some kind of switch that would prevent both the dryer and EVSE outlet from being used at the same time. This location is a very convenient one in the garage, but the problem is, a 25 foot cord would not be long enough to reach the car. Are there EVSE's with 30 foot cords? The ones I have seen max out at 25 feet. The second question is, does this meet electrical code?

I will consult an electrician, but I'm trying to do my homework a little beforehand. Thanks for any advice.


It does not meet code, and will cause problems when you try to sell the house. Do it right the first time, and it will save time, expense, and aggravation in the long run. If you want inexpensive, do the work yourself, or find someone that can do the work and make some arrangement with them. Get an outdoor EVSE and mount it on the side of the garage where the car will be parked. The GE Durastation is available for around $400, and is an excellent outdoor unit.

I think that it does. As alozzy suggested above, a Dryer Buddy could help, but your plug is on the wrong side of the wall. Dryer Buddy side steps code issues by being an appliance rather than permanent electrical work. However, as soon as you go through the wall, you're back into code issues with passing a cord through a wall. Worse, only the really expensive Dryer Buddy has a transfer switch. As far as I'm concerned the others are useless, and at $300+, you might as well put that money towards running a proper circuit.

Have you even gotten a quote, yet? :)

If you want to save a few bucks on wire consider installing a NEMA 6-50 outlet. This won't require a neutral wire that the EVSE ignores anyway, and it will still work to charge the Leaf at full speed.
