 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.

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. 

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.
