I know many have done this already but it's always good to check out different installs. Upgraded service from a 100amp panel to a 200amp panel. For a car charger and future shop in utility room. Already had a 200amp buried service to the meter but only 100amp into the house. They also ran 80' of #6/3awg Teck armour cable from the basement to between the garage doors at the front. Installed a Nema 14-50 for now. Tesla wall charger upgrade when I get the car.

Looks nice... but isn't that one crossover going to drive you nuts! ;)

It took me most of the night and today but I think I'm almost getting near to the point where I'm starting to consider thinking about whether or not there's a chance that with some serious thought involved and possibly a little counselling I could box it in and keep the door closed.
That or completely disconnect the 40 amp stove circuit involved, remove the wire and as our ancestors did, cook over an open fire.
I guess they didn't see me yesterday as I ran down the road behind their truck screaming for them to come back and fix it.

I don't even think you'd have to disconnect anything. Just remove 4 staples, swap the wire positions, and put the staples back.

I would *so* do that. :D

^^^ this guy made me add a missing screw to my dad’s cover plate on his Nema 14-50. He means business ;)

But then I would have to turn the main off to switch the breakers. AND THEN I would have to change my Apple Watch to chronograph and reset all the clocks in the house one at a time so they were all synchronized. Do you have any idea how much the grandfather clock I inherited from my great uncle drives me crazy? ;)

My fiance and I are building our house right now and I've talked to the contractor about doing the 14-50 220V outlet in the garage right now. First, they've quoted me $400, which seems fairly reasonable; anyone think I'm getting ripped off? Second, the contractor knew other people who've done these outlets for electric cars but he asked if I needed a specific setup for the outlet itself. I tried to pull up photos from the Tesla website to show him, but there are adapters included with the car that will work for most standard outlets, yes? The quote I've gotten from them says "standard 3 or 4 hole outlet and plate included". I presume that will satisfy my needs, correct?

I installed a 40A, 240V circuit for my Aerovirnonment EVSE. On the surface that may seem too light. However, once I calculated that our car would be on the charger for 14 hours/day (leave a 7AM return 5PM) that meant that I could get as much as 94 kWh on that charge. Thus, it turned out to be the more economical way to go.

Seems reasonable for your use. I will have occasions that require mid day recharge therefore wanted the option of 48 amps.

Hard to say on the price without knowing specifics but suffice to say it’s well within the reasonable range of the spectrum.

As far as making sure they do everything properly, check the attached document from Tesla on this!

14-50 4 hole plug (RV plug) is what comes standard with the car from my understanding.

Thanks to both of you. I actually noticed after I sent the message that they were quoting a 30 amp outlet. I don't know what the 14-50 is going to cost. I can see on the Tesla site that the 30 amp would only get me to 22 miles per hour while the 50 amp is more like 30; though I think those numbers are for the standard range, and I'm looking at getting the long range battery. Trying to decide if what I anticipate will be extra cost will be worth the quicker charging.

The LR battery is capable of 48 amp charging. It may be a bit more upfront but the Tesla wall connector with 6/3 wire to it on a 60 amp breaker will allow charging up to 48 amps when needed.
I am set up for this already. I just know I would regret not setting up for what the car is capable of. It’s more money up front but longer term worth it to me.

I'm thinking unless the price differential is a 2-3x jump I will want to install the 14-50, as I think I recall seeing maybe 37 miles per hour of charge on the long range battery. Just to have that quick charge capacity seems like a good investment.

Outlets are cheap. The problem is the size of the wire that they're planning to run.
  • A 30-amp circuit requires 10-gauge wiring. This limits you to charging at 22 amps.
  • A 50-amp circuit requires 8-gauge wiring. This limits you to charging at 40 amps.
  • A 60-amp circuit requires 6-gauge wiring. This limits you to charging at 48 amps.
I installed NEMA 14-50 outlets with 50-amp breakers, but I decided to oversize the wiring and ran 6-gauge. This way, if I ever decide to install a Tesla wall connector in the future, I just need to swap in a 60-amp breaker (~$12) and I'm ready. I would suggest that you do the same. The thicker wire is more expensive and harder to work with, so I would expect labor costs to increase as well as material costs. But it will help future-proof your home a little bit, assuming that electric cars take off as we expect them to.
If I were building a new home myself, I would *consider* running 3-gauge to support a 100-amp circuit (although that's probably going to be huge bucks). At the very least, I'd be sure to run a circuit for each car that fits in the garage, and maybe even another circuit to support an outdoor charger as well (since people regularly park in their driveways).

That’s exactly what I did. To avoid using conduit with my surface run wire I used Teck90 cable. Basically regular pvc sheathed 6/3 covered in metal armour and then sheathed in pvc again. Buried, surface mount, wet and dry approved.

I was very fortunate with my setup:

The house my wife and I bought about 7 months ago was a complete refurb, down to the studs. They updated everything, including the electrical service.

I only have a 100A box, but that's because everything is natural gas. Heat, hot water, stove, fireplace, and dryer. That way, there isn't a huge load on the system, especially at night.

The same guy who re-wired the house is also the Town's electrical inspector....and the guy I hired to install my HPWC. (How this isn't a conflict of interest, I'll never know...but who am I to fight small town politics?)

Anyway, he put me on a 60A breaker.

This means I'm maxed out on the single-charger Model S I'm taking delivery of any time now, as well as for my Performance Model 3 next year.

Now, I just have to wait to hear from my Delivery Specialist.

Cool! The mistake I made buying a 6 year old house 5 years ago was not running gas lines for the dryer and stove. Finished basement made it difficult. Would have saved me the 200amp upgrade. Are you going to install 1 WC with the 24’ for both cars or or 2 WC’s sharing load sharing the 60amp?
