Tesla Wall connector with 14-50 NEMA plug

And where are you going to get 277 volts? That is an odd number.

Yeah, that is an odd number. But you could see that on your power feed into your home.
Power companies will have to turn up the voltage to push enough power to cover the power loss that is created by wire length. So if you're closer to that transformer, you could possibly get 277v and if you're at the end you could be getting 220. I've seen 218v in some homes that are farther out in rural area's.

I feel obligated to mention that converting a 14-50 outlet to a hard-wired wall connector install is a very simple task, and is in keeping with the wall connector's install instructions, unlike adding a 14-50 pigtail.

Note: I don't especially think that the 14-50 pigtail is inherently bad or unsafe, but it's nearly as easy to do it "right".

I followed the Instructable below when I installed my HWPC NEMA 14-50 pigtail a few years back. Works well.

Tesla Wall Connector Installation

Tesla Wall Connector Installation: Having ordered a Tesla, I needed to prepare my garage for the charging system. In the US, the car comes with a charging cable that plugs into a standard NEMA 14-50 plug used for an electric oven. So the typical installation is to just install the ou…

I've never seen more than 253V on my Tesla screen while charging at home on 240V. It happens rarely and is just a single volt over +5%.

Actually, that is a voltage available in certain three phase installations. It's sometimes used in street and parking lot lighting, which is why Tesla added support in the Wall connector for Model S and X at one point. I wasn't sure they had retained that support in Model 3 and Y.

Yes, its available in 3 phase, but 99 % of homes dont have 3 phases available to them. Which was what I thought we were discussing with Wall connectors.
In an Industrial setting yes. 80% of my work is with 3 phase 480v and I've been doing this for 28 years. This Solar and battery charging is new so I'm learning as much as I can. We're working on installing a Tesla Solar/battery farm and EV charging station at my work, so I'm asking all the stupid question on this.

From a building with 480 volts, 3 phase power. One phase to neutral results in 277 volts, to which a Gen 2 Wall Connector can be hooked up. Most people aren't going to have this available to them, and it's unlikely that you're ever going to come across it in the wild, but it's a thing that exists. There are a few threads where business owners hooked up destination charging to 277 volts, and I've seen at least one 277-volt entry on PlugShare, although I don't remember where they are. Gen 3 Wall Connector does not support 277 volts.

Thats a great phrase right there!!

277 volts is available from a single phase of 480 V three phase service, generally only available to commercial buildings. Similar to 208 V three phase delivering 120.

This is my current plan, especially since the corded connector is now so much cheaper. At the moment my UMC just remains permanently plugged into the 240 in my garage, but I could unplug and take it with me if I have a long road trip and want the backup option.

+1 on this.

Super temped to buy one as spares. My 2 Mobile Connectors were both over 4 years old. Hmmm.....

This is the one.

Smart: Tesla is requiring you sign in to buy a mobile connector. No public buying and hoarding. All still out of stock of course.

It just went out of stock. It was in stock about 30 min ago when I checked.

ah yea, mobile connector with 14-50 is oos right now. The one with just the 5-15 is in stock though.

I show both out of stock..

It was in stock about 3 hours ago. Actually I am surprised it lasted almost a full day since last night when they came in stock.
