I would try for pulling a 20 amp 240v split phase circuit with 2 hot, neutral and ground. Install a 240v outlet and a 5-20 duplux with an outlet on each hot to share with other stuff. May need to be GFCI so that may complicate things or more expensive GFCI breaker.


Isn't that what I suggested, albeit with less detail?


More than likely this outlet would have its own breaker, but this is the reason why I want to be there when the guy shows up. It will have to be GFCI since it is outside and that is the code the around here. I don't want this to get too expensive as I said before this is just a rental. Any charging available at home is better than no charging. The house is over 70 years old and the wiring is kind of questionable as it is right now. A fresh run of wire with its own breaker is my safest option.

You have to have GFCI protection on a 240V circuit in your area? Or just 120V? Because that may invoke some cost savings buy not needing to purchase a GFCI breaker($100+)

Not 100% sure, but I'm pretty sure all outdoor outlets are supposed to be GFCI. I don't have a garage or anything unfortunately.

That may be the best plan, although it's a bit of a shame since a 240v 20a circuit would pretty much triple your effective charging rate.

Here's what I would ask to do in your shoes. Install a 20a 240v circuit and use a box like this at the end:

https://www.amazon.com/Siemens-TL137US- ... SFNNR3679C

That gives you your 240v charging circuit AND regular plugs all from the same wires (you run 4 wires instead of 3) you were going to run anyway. If you can manage a bigger circuit, that would be great, but 240v 20a will do the job. Offer to pay for the box and they might go for it.

I would also like to add, that a 240v outlet would be a good upgrade for the landlord. The future is EV! If you are a happy renter, bonus. If you move some time in the future, landlord still has the ability to offer charging for EV's.

The reason I suggested the configuration I did is that it uses smaller gauge, easy to pull cable, and gives you both 120 and 240 volt outlets. It shouldn't cost a lot unless the landlord wants a bunch of 120 volt outlets, instead of just one or two of them.

It might trip a standard 5MA GFCI. The built in GFCI trips at 20ma . I know L1 OpenEVSEs used to trip L1 GFCI's until the reference resistors were changed to 47K from 22K. 22K is the mfg recommended value but I do not think that they considered GFCI;s.. 22K is about 51/2 ma at 120VAC

OP, a suggestion: If the landlord is willing to run new cable to install a regular outlet near where you park, you can actually use it as 240v while you live there, then easily convert it to a regular 120V outlet when you move out. Here's how- the wire isn't any different for a 240v/20A circuit than it is for a 120V/20A circuit. The only limitation is that it could only be one outlet, but it sounds like that's the plan anyway. Run the wire and install a 2-pole 20A breaker in the load center and a NEMA 6-20 outlet for the receptacle. You can buy a variety of EVSEs that plug into that with or without an adapter. Then, when it's time to move, you can just replace the 2-pole breaker with a 1-pole one and the 6-20 outlet with a 5-20 GFCI outlet, and they'll have a regular 120v circuit there.

Why would you do that? A 240V outlet is more valuable. If it's a proper 4-wire outlet (two hots, neutral and ground -- not like a 6-20), you can get 120V from it with a simple adapter, if you need to -- no need to cripple the outlet.

The current version of the OpenEVSE uses a 300K sense resistor vs the old 47K. It should not disturb any GFCI. 47K is under most GFCI devices but 300K is minuscule.
