Install Wall Connector before or after receiving car?

I thought I would mention that another solution would be to install a weather proof box to hold the UMC while it's plugged in. Then it can simply be left plugged in. However, I'm sure you'll be happy with your new wall connector.

Yup. I had my HPWC installed on the same 50A circuit and had my electrician leave the NEMA 14-50 outlet in place so I could use it if the HPWC ever had an issue.

Yep - this!

Yep - this!

Interestingly, they wouldn't do that here because it's not to code. I assume code is worried that you might try to draw both at the same time.

Took the advice of some here and got the NEMA 14-50 converted to a HPWC today. Now I'm at least getting some indication that it works (green standby light, according to manual). Just got assigned my VIN yesterday too, so hopefully just a few more weeks to go.

Don't see too many pictures of outdoor HPWC on a post, so here it is, before and after.

You left the circuit at 50a, I assume? Looks like a clean install.

....and what gauge wire was used?

Yeah he set it at 40A at the HPWC because my breaker is 50A. Knob 8 on the dial inside.

....and what gauge wire was used?

Gauge 3. Should be plenty if I want to upgrade to higher amperage in the future. I was told it can probably go up to 100A.

Sounds good, but I would have gone ahead and had him increase the breaker to at least 60a, if not the whole 100a and set the wall connector accordingly as long as he was there. You never know when you might be in a real hurry for a charge.

Edit: Of course it's possible that would have needed a new permit, in which case I can see why you'd put it off.

>60A requires local disconnect.

Good point.
