Have you picked out the EVSE to purchase?

The answers to the above questions will impact how the new circuit is extended from the panel to the EVSE location.

The run from the panel to the EVSE should be as straight and short as possible. If the walls are finished, just run the wire in conduit on the surface. I would recommend putting any surface mounted wire in conduit, for protection, even if your locale does not require it.


The panel is on the exact opposite corner of the house from where the EVSE will be located. The total run will be about 90 feet. I have not picked the EVSE yet. Thanks.

I'd use BX/AC(flexible metal conduit with wires already inside) or Greenfield(same as BX but wires are purchased separately) unless you can run wires above ceiling.

Yes that is the choice for a finished garage. Are you sure you even want it inside? I thought the car was mostly going to charge outside? No need for an outlet, just hardwire the evse.

The trouble with wiring it directly is that it becomes part of the installation. It is always good to follow the NEC requirements but most Chinese and the OpenEVSE are safe but they are not UL approved. This is a problem if an over zealous inspector is involved.

In my opinion it is just better to have a 14-50R installed for large RV use. When you say EV everyone thinks they have struck gold.

So our juicebox is fed from a 50 amp cable. You can see the conduit on the left and a little on the bottom. This conduit is vented which is the only conduit you are allowed to use for a prefab cord where we live. Easy install (screws to the wall) then the cord lays in the conduit and the top snaps on top. Can be removed if something changes later. For us we wanted to be able to change it later (60 amp Tesla HPWC requirement) so we had the Nema 14-50 installed close to the box but on the garage side and then used a 25 foot 50 amp RV extension cord. Looks great. Works well. Paintable if you want.

OK and I recommend Clipper Creek. No inspection issues.

Clipper Creek certainly makes fine fixed EVSE's. If you want variable adjustment you need to go with the modified Tesla EVSE or the adjustable JuiceBox or OpenEVSE units. The advantage of the Clipper Creek units is that they are UL approved. I am an OpenEVSE person and they work for me. I have been before they added the GFCI test and circuit. The first units were crude in comparison to the current offering. Just like the Chinese units they worked under perfect conditions. The Tesla units use a Potter and Brumfield unit at 40A It is rated for that in pass through mode. I guess it it fails it needs to be replaced anyway.

I feel GFCI is important and it is part of the J1772 spec. I am not comfortable with a Chinese unit without it. As far as I know the Clipper Creek units fully comply.

An update to my situation. I saw a great deal on Amazon on a Siemens VersiCharge 30 amp EVSE charger. It was $359, so I ordered it. https://www.amazon.com/gp/product/B00MF ... UTF8&psc=1

Is has a NEMA 6-50 plug. So, I am planning on running a new Circuit. The total wire run will be about 90 feet. I did some checking on wire prices, keeping in mind the idea of futureproofing for cars and chargers in the future that can handle higher charging rates. I found that a 125 ft roll of 6-2 romex is about $165, vs, $115 for 8-2. If I am going through the work, I would think I would want to install a 50 amp breaker and the 6-2? Does this make sense? Is this the right type of wire? For this length run is this the right gauge wire? My garage is drywalled, so the plan is that once the wire gets to the garage wall from the basement, then I will run it in 1" PVC conduit. Is this conduit large enough for 6-2?

Is this the right type of wire?

The breaker should be sized for the EVSE, not just the cable. You can always swap in a 50 amp breaker if/when you get a 40 amp EVSE. Assuming a 30 amp EVSE you want a 40 amp breaker now. The link to the cable wouldn't load.

Thanks, fixed the link.
