So, I have my solar installers coming out in precisely 7 days. I'm paying them to install the HPWC for my 3 while they're here. Agreement is for a 60 amp circuit so I'll get 48a to the 3 through the HPWC. Waiting on a Signature Edition HPWC. No sign of it. In the meantime, ordered a standard grey HPWC, today. Not sure if it will show up on time. So, my question is this-- In the event that I have no HPWC on installation day, what outlet should I have the solar installers put in place that will have the closest wiring/box/etc to what the HPWC needs? I'm thinking in terms of ground/neutral/poles for 240v/60a service. I know the NEMA 15-50 is a 50 amp circuit. I'm sure I can talk them into using adequate wire gauge to support 60a on that outlet, and later 'upgrade' it myself. I've seen the HPWC installation video and the wiring is dead simple. I'm totally capable of killing the breaker, yanking an outlet, and installing the HPWC. But I'm no electrician, so I can only do this if the wiring provided to the outlet closely mimics what I'll need for the HPWC. And of course there's the matter of whether they pull the wires from the wall (behind the charger/outlet) vs via conduit. But all of those things I can deal with; if they use conduit, i'll use that conduit for my HPWC. If they do it behind the wall, I'll mount my HPWC over the top. So, what say you? Which outlet will be wired up with exactly the wires I need for a HPWC? Maybe this is a stupid question, but I'm currently using a 10-30 (via extension cord, from a totally different location), and I've been scared by talk of ungrounded outlets and the like, so I want to make sure, if I'm paying someone for wiring, it looks like what I'll need to hook up the HPWC later. Hell, even if I end up paying an electrician to swap an outlet for the HPWC later, it makes sense to have the 'right' circuit. thanks in advance!
