hardwired input cable?

 I don't have a garage (that isn't full of bikes and tools).  My electrician will only install outdoor charging stations as hardwired, and the OpenEVSE store will only sell charging units with a short, input cable with a plug on the end. 


Also this which means my 48 amp unit should be hardwired anyway (and OpenEVSE should be selling a hardwired option with various input cable lengths).


The electrician is already unsure about a "home-grown" device like this, so I'd rather not ask him to open it up to install his own cable.  Thus, I need to find a source for compatible outdoor-capable, round (to fit the gland) lead cable sold by the foot. 


Has anyone else had to do this, and where did you get the cable?


Thanks.

 Never mind.  The electrician was willing to run a cable from the electrical panel to the OpenEVSE box and replace the plug-ended supply cable themselves.  I wish that had been explained as a normal thing.

So, did he remove the plug and use the wire the came with it? Or replace the cable entirely/opened the unit to put in a new cable? FWIW I am in the same boat, mounting outside, and I think hardwired will be best for my situation.


OpenEVSE is recommended to be a plug-in appliance. If you hardwire the station becomes a part of the electrical system and may be subject to additional local, state and national regulations. That said OpenEVSE is designed to accept standard 3/4" electrical conduit. 


Remove the cable/plug and cable gland

Attach a 3/4" fitting to the hole where the gland was

run/attach the conduit from the electrical panel to the station 

pull the wires through

Connect wires to the breaker and station (Relay and Ground block).

I believe NYS code requires the 48amp unit to be hard-wired.  Certainly the electrician who was very experienced with EV charger installs would only do it that way.


He had no hesitation with opening the unit, removing the supplied plug and attaching the cable run directly from the house circuit panel.  I got the impression that was pretty normal even for the mainstream brand chargers.  Either way, it looks and works great.

You are correct, many agencies do not recognise the NEMA 14-60 or have contradictory recommendations, like a 50A plug-in limit which necessitates hardwire for 48A.


Removing the input cord is very common, the relay and ground connections inside are very familiar to an electrician.

Is there a outdoor/weatherproof plug box for NEMA 14-60 that would help here? I was looking but my search foo for such things is not working for me.
