Great you're helping your friends with their installations. Dave, keep up the great videos.

[@johnpoldo8817]

Outstanding installation, Dave. As an amateur electrician too, I learned a few tricks watching this tutorial. Thank you.

[@coastiesaurus6810]

I had a spare piece of FRP in the garage so I used it to protect the wall from wear n' tear. I placed in on the wall after I determined where the stud was then I put the wall connector on top of it. No marks on the wall. Remember to place the loop when feeding in the wire to code.

[@stbr0510]

Just installed my wall connector last week on a 50amp circuit. You should have looped the wires around per the instructions, not terminated them straight in.

[@nelsonchoy3862]

well done!

[@greglambert5154]

Couldn’t imagine a more enjoyable day than spending it working with Dave with a wall connector professionally installed

[@the4hunters]

Perfect!!!!

[@TheElectricMan]

I had to hire and Certified electrician to do all the work because I live in a condo and they don't allow anyone who isn't certified to do any of the work. The total cost I paid was about $5000 CDN for the installation, drawings, electrical meter, and wall connector unit.

[@johnpoldo8817]

Sensitive to safety, I feel compelled to complete Dave’s title: “Installing Greg’s Tesla Wall Connector, You Can Too….” but only if you are experienced working with high voltages. Mistakes can cause serious injury, fire, or death. If not certain, hire an electrician. Some local codes require a permit and inspection too.

[@evdave528]

Correct! Hire an electrician to install it!

[@mrtichy11]

The two hots and ground cables should have been run on the right and up, zip tied and the connected from the top. I assume that is for more accurate temp detection.

[@pandaturbo]

Good video!!!

[@PeterGregg]

Thumbs up 👍

[@davidherringgo]

Excellent tutorial you will love that wall charger Greg. That's the way I charge my Model 3 . Took 5 months to get a good WiFi signal ,but Im cookin with gas now . .90% of my charging is with this wall unit . And I think trickle charging gives the longest longevity to your battery.

[@evdave528]

Thanks for sharing

부정이 긍정으로 역시 멋져요 🎉😮. 사실인것아 멋네요😊

[@ernestgalvan9037]

Here in Texas, they are also called “humps”

[@rhmbob82]

Great video! I’m also waiting for a blue MY with white interior!

[@evdave528]

Greg ordered the same as you, your brothers and didn’t know it 😊

[@brianbeasley7270]

Dave, you should have looped the input feed wires over the top inside of the charger base plate and strained relieved them with the included cable tie on the connecter explicitly placed on the side for that. This is exactly what the Tesla manual says to do. Wires should not be "hung" from their connections if there is any weight on them. Also you should include the lock nut and end bushing so you don't have the sharp edges at the end of the conduit for the wires to abrade against. RTFM and don't show bad practices. Electrically, this charger works fine. Mechanically and by code, not so much.

[@brianbeasley7270]

Thanks for "liking" the comment, Dave. Not trying to be critical for no reason but these things can be dangerous which is why we have codes. There's also another interesting code that is worth mentioning. If a NEMA 14-50 outlet is installed (with all four conductors properly connected to the outlet-two hots, neutral, and ground on a private circuit (even though most EVSEs don't use the neutral), a 50 Amp NEMA 14-50 range cord can be attached to the EVSE to plug it in for no more than 40 Amp continuous draw use (50 Amp breaker). However, and here is the code--- that range cord needs to be trimmed down to only extend from the EVSE by 1' (12"). I believe this code is because the circuit protection for the human is in the unit and the code writers don't want a long extended run of a 50 A cord run from the EVSE to the outlet so if it get's cut by someone running over it, they won't be electrocuted. Since it is limited to 1' length, the probability of damage is small since it can't really dangle down to the floor. (In most EVSEs like a Tesla unit, the neutral conductor in the range cord need not be connected and can be either trimmed and properly capped.) Enjoyed the videos but let's show good practices because lots of people respect your work.

[@coastiesaurus6810]

As per the TESLA Wall Connector Installation Instructions it is shown for All entries to have a excess loop in the box, top, bottom, left or right, gotta have the loop. Step 4: Route Wiring Through Wirebox 1. Route wiring into selected entry point and through the service loop channel on the right side of the wirebox.

[@sitechca70]

@@brianbeasley7270 Glad you caught the wiring and lack of insulating bushing violations (at both ends). This "pro" also failed NEC by not properly securing the conduit to both interior/exterior walls. Sad that this video is supposed to encourage others. At 3:06 you can see numerous shoddy exterior wall penetrations that's not part of this install, but a sign of low quality work.

[@cbromley562]

No smoke, 12kW and 48amp…the perfect scenario.

[@tested123]

just installed my first one. 6/3 teck wire into the bottom. had to add a closed nipple and coupling to the teck connector to get it to fit. ground bushing wouldnt fit due to lack of space. cant do this to code in canada.

[@kennethstevenson6336]

There called “humps” in Georgia also….😂😂😂

[@glenb1356]

I just ran #4 wire about 60 feet to the garage. I ran 4-3 w/g, probably 4-2 w/g was all that was necessary. I had to use 1" conduit, and it was a snug fit!

[@evdave528]

#4 is tough but run #2 in a1” it’s a bit more snug. Cable lube!!

[@bluehugh2]

Looks like #6 wire being run with a few relatively sharp bends. Won’t that cause higher resistance under load?

[@roberthicks686]

Greg gave a thumbs up but did he subscribe? hehe

[@Magicinstalls]

Whoever did those 90s on the main feed wires didn't know what they were doing

[@mowcowbell]

I wondered the same thing. Never have seen a main feed like that before.

[@roychen2404]

Hi Dave, I just installed the wall connector, but still waiting for my model Y, is one LED keep blinking after commission?

[@jerryberg5767]

Super informative. Thank you. A question: my electrician supports wiring a cord with plug into the TWC and then plugging it in to a 240 outlet. Are there pros/cons to that approach?

[@evdave528]

Yes, a plug shows only 40 amps continuous, best to hardwire with disconnect if local code requires it. Then you get a full 50 amps of charging. 60 amp breaker to feed it.

[@jerryberg5767]

@@evdave528 I suspected as such, thanks.

[@ablanco143]

Thank you for all your helpful videos. Quick question. Can a wall adapter be installed on the exterior of a home?

[@rborroto]

Yes

[@frankcoffey]

It can be and there is a metal stand available for it if you want to place it away from the house. There are also several after market vaults you can buy to protect it.

[@batyrenko]

Please let me know what kind of wires do you use for Wall Charger? Thanks.

[@keithharrington8715]

As an electrical guy, you did not provide enough information to answer your question. Individual wires (conductors) have Insulation rated for different environments but must be in conduit. Cables do not need conduit normally, but most building departments want conduit when the wiring is not protected by the wall (people side of sheetrock vs inside wall side of sheetrock). Wire sizing is maximum, maximum, amps of charger times 125%. A 40 Amp charger needs at least 50 amps of wire and breaker. This is in section 625 Electric Vehicle Service Equipment (car charging). There is also a requirement for a gfci if you put a receptecle in for the car charger section 625.54. For you wire size, section 110.14 says that the wire connected to the breaker should be in the 60 degree Celsius column of table 310.16. Can you do this yourself, yes. Is there a lot to know, yes. If you want the satisfaction of doing it yourself, do plenty of research and considering hiring a pro at least as a consultant to get that knowledge. He may have solved a problem you did not know you had 5 times last week.

[@johnpoldo8817]

My question is slightly off-topic, but remember Dave installing both a Wall Connector (WC) and a NEMA 14-50 EVSE receptacle. Maybe it was at his or a family member’s home. We know the WC doesn’t require white common wire. But, do other EVs such as Mach e, ID.4, Taycan, Audi, Bolt, Polestar, Kia, etc require the common wire for 120 v while charging? Add the common wire or eliminate it?

[@rhmbob82]

Don’t know what the others require, but I thought about the same and plan to pull a common wire even if it won’t be used with the Tesla wall connector. Easier to do it now than later.

[@johnpoldo8817]

@@rhmbob82 Bob, I too added the common wire on two NEMA 14-50 EVSEs installed. I wasn’t certain if some other EV brand requires a common wire. Another concern is the receptacle might be in a semi-public setting and someone might plug in any 240V apparatus (ie welder) which requires a common. We don’t want any smoke.

[@evdave528]

In the charge point walk connector, on the 14-50 reception was only ground and single Phase 240 no neutral. Mach e charges fine.

[@dheerajpalur6000]

Nice.. what size wires did you use?

[@evdave528]

I think he used #4 at about 12 Feet

[@rayhaanpathan4872]

Don’t you need a neutral wire to complete the circuit ? Please reply with a response thank you so much

[@evdave528]

No neutral needed

[@rayhaanpathan4872]

So when I make the connection in the panel , I put my ground to ground and both conductors to the double pole breaker correct ?

[@evdave528]

I suggest you hire an electrician, best practice

[@johnpoldo8817]

Greg says, “I spent enough charging your car!” An electrician would have charged him $250+ materials so he owes Dave multiple charges plus dinner at a fine restaurant. Please, no Scottish breakfast.

[@paulmartinez5944]

Do you need a disconnect for extra safety?

[@PeterGregg]

Why does the wall connector need wifi? Seems intrusive, they can shut you down?

[@Oncampus2k]

So it can receive software & firmware updates.

[@evdave528]

Software control and future load sharing

[@mowcowbell]

If your concern is about external control, then shut off the wifi to the unit.

[@paulmartinez5944]

Can I use 1 inch conduit?

[@evdave528]

You will need a conduit big enough to allow pulling the wire through it but depends on wire size. #6 will fit into 3/4” conduit

[@keithharrington4595]

The National Electric Code has a chart....informative annex C for pipe type, pipe size, and conductor fill. C.12 indicates for example that a total of 8 number 6 thhn wires can fit into a one inc pipe.

[@Ojeramup12]

4 or 6AWG. ?

[@evdave528]

I think it was 6

[@Tworth23]

Dave. How do I get the free 1000 miles of free supercharging. Buy a Tesla with your link?

[@evdave528]

Unfortunately, the referral to get 1000 free supercharger miles is expired. The referral link is only good for solar now unfortunate but it is still in awesome vehicle.

[@superfoodtravel1540]

Electrician would have changed around 250$

[@mowcowbell]

Sounds about right. I was charged $250 in Oklahoma for installing a NEMA 14-50 outlet about 3 feet from my 200amp breaker box in my garage.

[@dahlyah]

Did u Commission?

[@jimkirkpatrick7269]

Horrible.
