can you share your setup I am little confused .A picture would be greatI installed a 14-50, then bought a 14-50 dryer cord to wire into my Tesla wall connector. The wall connector is plugged into the 14-50. Works fantastic, and future-proofs my house somewhat. That way, when I move, all I have to do is unplug my wall connector, and unscrew it from the wall. The house is still left with a 14-50 for the next EV or PHEV.
it works so well that I installed a 2nd 14-50 on the other side of the garage for a 2nd car at some point in the future. I was doing some electrical work anyway, and it just made sense to save a bunch of additional work later.
It's a "portable" HPWC. Instead of hardwiring it, he's wired in a dryer cord. It can then be plugged in to a 14-50 receptaclecan you share your setup I am little confused .A picture would be great
In a word, options. An outlet gives me the option to use other equipment; namely a welder. Another option is to use the mobile connector (MC) if the HPWC went bad; HPWC can be unplugged and the MC connected in a pinch.can you please tell me why you would want a 14-50 along with HPWC and share a pic of your setup

Does anyone know if you can fish the wire to garage from electrical panel from outside the house.
Thank you it looks nice and now I got it .I also liked the way you took the wire from outside the house .I am doing the same rather than going through drywallOn one side of my garage, I ran it insideView attachment 636816 View attachment 636817 the wall, on the other, I went along the outside through conduit. It’s all 8/3 wire, about 60’ from panel to outlet, on a 40amp circuit breaker. I still have to install the box and hook it all up.
Corrections:The [functional] cost to use a plug is a drop in peak charging from 48A hard wired to 40A with a plug. Since the car is typically charged at 10A and never charged at 40A, the cost to me was negligible.
Not sure what you’re “correcting.” You’re right; a circuit’s continuous load should pull only 80% of a breaker’s capacity. Thus, a hardwired HPWC will pull 48A of current on a typical 60A circuit and a HPWC with a NEMA 14-50 added should be limited to 40A on a 50A breaker/outlet. The point of the post is losing 8A of charging capacity with a 14-50 vs hardwire; something to consider if someone is thinking about going with a HPWC/14-50 combo.Corrections:
In my case, 100 Amp circuit breaker and cable. We have two Gen 2 chargers - driveway & garage. The "master" HPWC is configured at 100 Amp circuit capacity. The HPWCs will provide up to 80 Amps total charge current. My friend's older S can charge at 80 Amps when he visits. If my wife's 3 and my S are both connected, then the HPWCs divide 80 Amps between the cars.
- As I understand it, circuit breaker rating must match outlet rating to reduce risk of circuit / outlet overheat and fire. You can pull heavier gauge wire if you want the option to later install circuit breaker and directly attach HPWC with higher Amperage capacity.
- In US, EV charging is continuous load. It is limited to 80% of circuit's rated capacity. Thus, for 50-Amp outlet and breaker, 40 Amps is the limit.
- When you configure HPWC - internal dial for Gen 2; wireless for Gen 3 - set it to circuit breaker / outlet rating. 50 Amps in your case. The device does the arithmetic, will accordingly limit current to 40 Amps in your case.
should be "sometimes"Beware the Canadian 14-50 outlet through which is almost always wired to a 40A breaker.
