I give up. Not worth the negativity.

I give up. Not worth the negativity.

Right, but others may come across this and be able to use some of the ideas I and others have suggested.

I realize this has already been covered, and the OP already has installed a TWC, but I post this for anyone who may have a similar situation that comes across this. You will not be happy charging from 120 volts unless you drive just a little. If your apartment has a dryer, consider using that...

I realize this has been covered above, and OP already has the wall connector installed, but I write the below for others that may come across this. Tesla mobile connector or wall connector do not require neutral. It is common for appliances that are strictly 240 volt, like the Tesla...

But if on a sub panel, what size cable should that be? Do you want some other miscellaneous circuits on the sub panel? I found a really nice calculator that does a lot more than the Mike Holt Electrical Toolbox...

Neither Mike Holt example specified hot environment, and there is no derating for any reason in either example. I concede the point that any 75˚ wire, not just THHN/THWN wire, can be used as long as it is suitable for the environment in which it is installed. I just mentioned THHN/THWN wire...

I was discussing two specific circuits that are feeders to a sub panel. The circuits for the capacity of the feeders I was discussing, with the wire size shown in the Mike Holt Electrical Toolbox need to be 75˚ rated wire, which is most often THHN/THWN wire run in conduit.

If you want to install two or more circuits for EV charging using a sub panel, the feeder to the sub panel needs to be designed for continuous loads. For example, if you install a Tesla Wall Connector using a 60 amp breaker and a NEMA 14-50 (or 6-50) on a 50 amp circuit, which will charge one...

My Gen 3 Tesla Wall Connector can only be used on 208/240 volt circuits rated 15, 20, 30, 40, 50, or 60 amps. No provision for running it from 120 volts.

I think he means 24 amps. If you are using the 3-wire or 4-wire dryer style adapter with the mobile connector, it automatically limits charging to 24 amps (80% of 30 amps).

Or, if you only have 3 wires (hot-hot-ground) you can install a NEMA 6-50.

Thanks, Wayne, for this. Presumably what I have now was inspected when the house was built in 2006, (I purchased it in 2011) and nothing has been changed between the meter and the three service disconnects, which are in actuality Service Equipment rated Generac transfer switches, each with a...

I have had similar experiences with professionals, such as the electrician I mentioned in my post above, and agree they do not want a homeowner telling them how to do their job. You make a very good point, and I will take your advise. Thank you. But if they wire this up exactly the way the...

The bar behind the meter with 8 lugs is a continuous bar which is bolted to the aluminum meter box The grounding electrode conductor (GEC), copper water system in the house, the two neutrals (yellow stripe) coming in from the POCO, the three neutrals going to the three main service panels, and...

Tesla says no change can be made on the stringing of the panels into the inverters, that it is configured for optimal production. Perhaps when they actually install it they will change it, but I suspect the installers have to install per the drawings. But a couple of errors were made on the...

Apparently not in our neighborhood. AFAIK I will be the first solar installation. Tesla says 20,000 kWh annual production. Any thoughts as to my question as to why the four 1x6 groups are combined into two home-runs to the inverters?

I have a 60 kW generator.

14.4 kW system, no Powerwalls. Just trying to get a little power to offset the power used by our MX and MY cars, our house consumes much more power than this system will generate. I also have to wonder why some of the panel groups are separately wired and some are tied together at the roof...

Wit no intention to be negative, my understanding of full self driving, as well as the basic Autosteer, is it is only for use on limited access highways. That is, unless you have the beta version that is for city driving. At least that's how I use it. Am I mistaken?

I took advantage of an early "only available this day" offer to pickup my Model X Plaid on June 30. At that time, it was scheduled for sometime in the August-October time frame. I got an email saying that there were several Model Xs available, one day only. I got the email when I had gone out...

Tesla just changed my wife's MY LR estimated delivery from December 26-December 31 to November 24-December 22. (Ordered on May 6, 2022.) If the tax credit is reinstated for Tesla, is there a tax credit limit of one car per year or other period?

If you are upgrading from a 120 volt to a 240 volt circuit, why not go with a circuit that can take advantage of the full capability of the Tesla Wall Connector? Going from a 40 amp to a 60 amp circuit should not cost that much more, which if using THHN wire in a conduit will just be an upgrade...

I was just trying to point out that a 50 amp receptacle in a normal house is not that common right now unless they have a need for that (such as a home workshop where they do welding, an RV hookup, have an EV, etc). Really it is more about convenience if you travel to visit friends at their...

Because it is much less expensive to charge at a friend's house, than go to a supercharger. Actually it is free (to me) since my friends always refuse reimbursement. And more convenient if staying overnight as it will avoid a stop at a supercharger. Since I have a Tesla Wall Connector, it is...

When traveling and visiting people who live in a single family house, a 30 amp dryer receptacle is much more commonly available than a 40 or 50 amp receptacle, which most houses have if they have a range, but to access a NEMA 6-50 or 14-50 range receptacle usually requires pulling the range out...

Wayne, thanks for this. Something to definitely think about. It will be interesting to see how Tesla does this install. Hope the OP posts updates with lots of pictures!! Eric

I understand your desire not to do anything to delay your installation. So your installation will proceed with your existing 100 amp meter main ("MM") and your existing load center, presumably as follows: A conduit and the wiring will need to be installed between your existing MM and the...

I have found this thread very interesting, and I would like to chime in on this, and am curious if you have come to any decision. 1. You have what is called a "meter main. Here is what they look like inside. This one is 200 amps. Yours is very likely only rated for a 100 amp breaker. A 200...

I did just that, result below. In my experience, houses with more than 400 amp services often have services that are over designed. Note my house is set up with a 600 amp (CL480) Service, built in 2006, and even with two 48 amp EV circuits, Mike Holt's electrical toolbox says I only need a 350...

My 600 amp (CL 480 meter) service is similarly split, but into 3 200 amp main breakers. The transfer switches contain the main breakers within them. Cables from the load side of the meter go to each transfer switch through the "gutter" above the meter and transfer switches, and each...

That is the best description of how real-world loading of residential electrical service works that I have ever read. And it is why I say that often people overestimate their need to upgrade their service. This is an old post, but if you add an EV to a 100 amp service you can install a load...

Besides the DCC, another company also makes an EV load shedding device: https://shop.blackbox-in.com Less expensive than the DCC. Can be purchased at Amazon. Installing such a device on whatever panel you now have negates the requirement to do any upgrades to transformers, wires, panel size...

8,500 s.f. + 2 two-car garages each with 1 ton mini splits. Garages have insulated overhead garage doors. The house could easily have been set up with a 320 (so-called 400) amp service. But I am glad it has 480 (so called 600) amp service since it could support an EV in each garage bay! The...

When a dryer is first turned on it may draw ~23 amps, but when it heats up after a while the thermostat will turn off the heating element and the only load will be the motor and the control electronics or timer motor, just a few amps. It will then cycle the heating element on and off until it...

If you have a 400 amp electrical service, installing Tesla power walls becomes complicated because as others have said their gateway is rated at 200 amps which will be satisfactory for the vast majority of homes. Therefore my answer to the OP's question is: If you are not having any problems...

I found the problem! One of the wires was pushed too far into the terminal and whilst there was enough contact for the WC to operate under no load, once the load increased obviously the contact with the terminals started heating up. Kudos to Tesla for putting sensors in the WC to detect...

I have two gen 3 wall connectors installed. I have a new MXP that I recently got and a MY on order. The one closest to my MXP has the 3 red light issue. Call this WC1. The one that will be used by the MY, the cable of which will reach my MXP, and when connected to the MXP, has no problem...
