Sharing a 40 amp circuit with Oven?

Thanks, so in addition to the 6-20 outlet I need a double pole 20A circuit breaker for the 240V.. Its odd though, I look at my other breakers and they all say 120/240V.. But I think its just that on the US grid one line is only 120V so you need two to get the 240V

Out of curiosity, what would be the type of outlet to install for 20A 240V? Is it the NEMA 6-20? I could easily install a 20A breaker and attach it to the wire in my existing box temporarily, and if needed in the future do a sub pannel.
While I do think cars should use less in the future, I am not anticipating it anytime in the near future unfortunatelySeems like they are only going up in battery pack size not down.
Yes a 6-20.
Upgrade after you run for a bit. I bet you find you don’t need to.
You’ve listed progressively larger vehicles.
Every released car you listed is more efficient than it was a year ago.
Yes, if he buy’s a Semi I don’t think 20A 240V will cut. For Model Y he will probably be fine. Since it’s essentially done he should try it. Plenty of folks get by with less.

Doesn’t look fixed. Still says watts instead of watt-hours. ¯\_(ツ)_/¯
Is the romex wire Orange? If so it should be 10 gauge and you could get a few more amps. My eyes can't quite see. I think 10 gauge romex would pair to a 30 amp breaker and you would get 24 amps continuous or about 22mph.

Yeah, it has a Orange casing over the wires. I was just using my electrical wire stripper tool and putting the copper wire in the holes to try and determine the gauge.. it fit perfectly in the 10 gauge hole... but your right all the info I see online says if it is orange it should be 10 guage.
Darn, looks like they only installed 12 gauge wire
Nah, that is 10 gauge. 30 amps.
Thanks, I am glad that was pointed out, I can deal with 30A charging, the 14-30 plug type should deliver about 22mph which is more then enough I feel for my driving.
Very slightly off topic. Can the Tesla display be configured to read miles per KWH like the leaf?
Tanks.
Now the fun begins.
If it’s 10-2 it needs a 6-30 Outlet
If it’s 10-3 it needs a 14-30 Outlet
10-2 is Black, White and Copper
10-3 is Black, White, Red and Copper
Unfortunately Tesla does not make a 6-30 Adapter for the UMC.
But these folks do ($75)
NEMA 6-30 Adapter for Tesla Model S™/X™/3™ Gen 2 – EVSE Adapters
Any EV Outlet requires a GFCI Breaker. (~$100)
If you install a wall connector you don’t have buy any adapters and it will work with 10-2 or 10-3 and it does not need a GFCI because it is hard wired and no outlet is exposed. And you keep your UMC with the car.
You can upgrade the circuit on the wall connector in the future if you want but 30amp is plenty.

The k in kWh is not kilometers. It’s kilowatts.
You can run Tesla in Metric or English units.
Range is in miles or kilometers (or battery percent full)
Speed is in mph or kph
Efficiency is watthours per mile or watthours per kilometer
Charging and battery capacity is in kWh (kilowatt hours)
Power is in kW kilowatts (how many watts going into the motor, regen limited by, how fast you charge)
I think Tesla’s way of displaying efficiency in watts per mile is simpler than what other EV’s often do which is kw/100 miles or something like that.

I’m probably not explaining myself well. Sorry. In the leaf one can look at (in metric fur example) 6.2 km per 1 kWh of power (or 4 ish miles per KWh of power). I’m asking if there is a way to see average kilometers per kWh in the Tesla.
Thank you.
I had updated my reply before you quoted me. But no, Tesla does not display efficiency that way. I hate distance per 1 kWh. Energy used per distance makes more sense. But it’s what ever you’ve been raised on. You’ll get used to it.

No, there is not. The display will only show watt-hours per mile (Wh/mi) or watt-hours per kilometer (Wh/km).
Yah. We will. The wife is ordering her model 3 AWD Red with white interior and sport rims on the day after April fools day.
.And so you are getting this backward, like I have seen many people do before. Larger and larger battery sizes lead to lower necessary charging speeds over time, rather than higher. You are defaulting to the idea of: "I need to fill [FULLBATTERYAMOUNT] overnight, so I need XXX amount of charging power." But that's not how that works. You drive XXX distance to work every day. As cars continue to improve in technology and range, that does not equal you living farther and farther and farther away from work. So you drive the amount you drive independent of the car's capabilities. And if the cars get to 400 and 500 and 600 miles of range, that just equals more and more leftover that you still have every night when you get home that doesn't need to be refilled and is really alleviating the need for much faster charging to have enough for tomorrow's driving.While I do think cars should use less in the future, I am not anticipating it anytime in the near future unfortunately
From the pic, it was hard to see, but the wire does look red, presumably orange and 10 gauge.
Having said that, I too was a Volt owner, with a NEMA 6-20 with 12 gauge. I swapped out for a 14-50 and 6 gauge, when I ordered the Model 3. As others have noted, you can get by with the 6-20, but you may eventually want to upgrade. If the panel's in the garage, it won't be too hard.
