obviously, depends on how far the pull is, but the diff for 125' of cable is $130. And yes, that was ~10% for my install. But after purchasing a $55k car, I'm ok with the extra bucks. But worrying about spending an extra $100 and not being able to sell it to the next guy is just plain whack. The buyer of your house may not even have a EV, or may get free charging at work, and not care.
btw: if you want ROI, use the smallest charging capability for your daily drive and purchase a used LEAF.
...and switch the breaker hopefully. It's not allowed to have a 50A outlet type with a 60A circuit breaker.If I move, I'll take the wall charger with me, and replace where it was with a 14-50 outlet.
Plan ahead for that 2nd Tesla…sure, almost no one needs a 60 amp circuit. But why not future-proof? The labor is the same, only a few more dollars for materials.
Yes, it is possible to do that, but you or your electrician absolutely need to do a load calculation to see how much load you can reasonably add to that panel. The good news is that ACs usually have large motors in them and are intentionally overbreakered for starting current purposes. You need to get the nameplate ratings for the two ACs, including their air handler and any strip heaters(assuming you have electric heat for those cold NJ nights)Can this work?
No, that's 100 amp service.That's a 200 Amp service though, isn't it?
Pretty sure its >always< but I guess it might be possible to feed two main panels from a common disconnect. It would be silly, because then the wires to both panels would have to be rated to the full breaker rating.Typically a sub-panel has a large breaker leading to it.
NO, NO, NO, a thousand times NO! The HPWC( any gen) can be set as low as 12 amps, and that's how much breaker you need. See page 5 of the gen3 installation manual, where it tells you the breaker/current you'll get, from a 15 amp breaker supplying 12 amps continuously to a 60 amp breaker supplying 48 amps continuously.Consider if you actually need the amount of power that's required for a 3rd gen Tesla charger. It's only a question of how long it takes to charge, and any Tesla will fully charge overnight using a 30A circuit off a 14-50. 3rd gen is wildly overkill and requires twice as much.
Thank you for the comments. Yes, I would like to have flexibility with charging. I’m not an electrician and I don’t know too much but electric stuff, so I’m reading all this very careful, It’s really appreciate it.No, that's 100 amp service.

Notably @Stanlana could almost definitely swap either(or both) of the AC breakers for a tandem duplex breaker, which supplies two 240V circuits in the same two-space space the current AC breakers each take. Still, there may not be enough capacity left in this box for another big load.

But I am still going to need 60 AMP to get max charging speed of 48 AMP, correct?Thank you for the comments. Yes, I would like to have flexibility with charging. I’m not an electrician and I don’t know too much but electric stuff, so I’m reading all this very careful, It’s really appreciate it.
Yes, but you will NOT remotely get it from that 100 amp panel. There's just not enough capacity, and you'll be tripping the main breaker every day.But I am still going to need 60 AMP to get max charging speed of 48 AMP, correct?
Yes, that I understand, thank you. So what are my options?Yes, but you will NOT remotely get it from that 100 amp panel. There's just not enough capacity, and you'll be tripping the main breaker every day.
Even if we ignore the 6x20 amp circuits and 10x15 amp circuits, that panel would be in a potentially overloaded condition. Assume each AC is using 20 amps(which you shouldn't assume), that's 40 right there, then add another 60 for the charger, and you are at 100amps, the limit of that main breaker. Add a refrigerator, a range, some lighting, a hair dryer, maybe a laptop charger and a big screen TV, and you have a guaranteed main breaker trip.
Yes, But then I don’t need Tesla charger, I can just getNEMA 14-50 plug, but where do I put 50 amp breaker?Don't think a new panel is needed. Just get a 50 amp breaker and set charge to 40 amp. Even at 30 amps the car will charge at 27mph which is more than enough to get u close to 90% in 8 -9 hrs from no less than 30 miles left on the battery. Wait for supply.prices to come down before a big electrical Job like getting a new panel or subpanel.
honestly after looking at your panel board picture again, you are using double breakers for every open slot. Unfortunately, it is unsafe to move the wires form 2 physicals breakers (4 wires) into another breaker as it would work but be UNSAFE.Yes, But then I don’t need Tesla charger, I can just getNEMA 14-50 plug, but where do I put 50 amp breaker?
I wouldn't be super surprised if you can't even get another 32 amps out of that panel (putting a 40 amp breaker on a 14-50 is allowed). You NEED to get a load calculation done.Yes, But then I don’t need Tesla charger, I can just getNEMA 14-50 plug, but where do I put 50 amp breaker?

Here's an example of how you'd shoehorn another breaker in there...
Square D Homeline 2-30 Amp 2-Pole Quad Tandem Circuit Breaker HOMT230230CP - The Home Depot
The Square D by Schneider Electric Homeline Quad-Pole Tandem Circuit Breaker consists of (2) double-pole 30 Amp breakers. These innovative circuit breakers help free valuable load center spaces by combiningwww.homedepot.com
Note that that breaker is only an example, and may not fit your panel at all. We don't know your panel model/maker, so I can't get more specific. Assuming that style fits, I see there are 30/40 and 30/50 pairs available.
Also note that the panel itself MIGHT not allow any more circuits. We won't know until there's a picture of the model/installation info(usually inside the door).
