Tesla Wall Connector Gen 3 - DIY Install Tips Tricks Secrets 2020

Tesla Wall Charger Gen 3 - Level 2 EV Charger DIY Tips Tricks and Secrets Revealed.

Save money and easy install a new Tesla Wall Charger yourself. This is an instructional video How-To tutorial on installing the new 2020 Wifi Tesla Wall Charger Gen 3 Level 2 charging at home. It can be used to charge your Model S, Model X, Model 3, or Model Y in your garage.

We go over the electrical differences in choosing between the Tesla Gen 3 Wall Charger, the CMC (Corded Mobile Connector), and the Tesla UMC (Gen 2 Mobile Connector), the differences in charging rates of installing a Tesla Wall Charger vs NEMA 14-50 receptacle, and how fast you can expect to charge your vehicle by the Tesla Wall Charger vs Tesla Mobile Charger.

This video is intended to discuss a technical overview of core concepts, and with the new knowledge, instilling confidence for someone with little experience doing electrical work, to install your own Tesla Wall Connector or NEMA 14-50 adapter to provide you with Level 2 EV fast charging at home with just some basic supplies and tools available at Amazon or most big box home improvement stores, like Home Depot or Lowes. Whether you need a Model 3 charger or a Model Y charger, this video has got you covered.

This was an amazing explanation. You’re like Bob Villa and Bill Nye the science guy put together

[lancegivilancz]

I rarely if every comment on videos, but this was the absolute best explanation on wiring the Tesla connector as well as explaining the generals between ground bars, neutral and the legs of power. Thank you.

If elected, I will pass a law that ALL instruction videos be like this one.
Great job! Thanks for posting.

For those watching today - you cannot use 6 gauge 6/3 NMB Romex with a 60A breaker - THIS IS NOT TO CODE. However, 6/3 NMB Romex with a 50A breaker = to code (just set the Tesla V3 wall charger to 40A charging when commissioning and that is a safe setup that meets code).  

Unfortunately for me, 7 months ago I watched this video, ran out and bought a long (75ft) run of 6/3 NMB Romex and a 60A breaker thinking I could use the Tesla V3 Wall Charger's full 48A capability and learned AFTER my install that this combination was NOT to code. All was not lost - after learning this, I swapped the 60A breaker for a 50A breaker and set the V3 Tesla wall charger to 40A charge rate which is safe, to code and works really well. If you want to get the V3 Wall Charger's max charge rate (48A), you will need a 60A breaker - paired with conduit and THHN 6 gauge or MC 6 gauge or 4 gauge Romex.  

This is a GREAT video and it helped me a LOT but the suggested use of 6/3 Romex and a 60A breaker is not to code unfortunately. I found this out after I purchased the materials and ran the cable.

Wow, this is far and away the BEST video I've seen on this topic. I've seen much longer videos that ramble on and on without saying much. This one is spot on: concise and well-organized, with all the info we need. Thanks!

[stonecoldsteveaustin]

I HAVE NO DAMN IDEA WHAT HE WAS TALKING ABOUT MOST OF THE VIDEO
BUT THE FACT THAT I AM GOING TO PURCHASE A TESLA AND GET A TESLA CHARGER AS WELL MADE ME LEARN ALOT

CAN WE GIVE THIS MAN A HELL YEAHHH!!!!

[coastiesaurus]

I had a short run, only 12 foot, I ran the individual 4 AWG wires, Red, Black, Green in 1" non-metallic conduit, did not have to wrestle with the wire, more relaxed. Since the Gen 3 already comes with a 24' lead the length was sufficient for both our cars. Great video.

[sambitshankar]

I wish more people see this! This was well explained.

[dwayne]

You gave me "Home Improvement" vibes. Specifically, The neighbor Mr. Wilson lol. Great video btw

[deezyb]

After hours and dozens of vids looking for info that I need, this was the most informative. Thanks.

If you're using ROMEX you HAVE to get a size larger to account for the thermal increase from the extra insulation of the wire jacketing. You should change out your wiring to ROMEX 4g or THHN 6ga for a 60amp circuit. Overloading the ampacity could cause a fire.

I too RARELY comment on videos but dude! VERY well done!!! Wife and I are going to test drive a model Y this weekend. Never had electric car before.

[anthonydouglas]

This answered all of my questions. Thank you. Every other video shows it already installed leaving you with why or how, and still no answers

[erikstieg]

This is a great video!
there is some miss information at 4:57 in regards to Allowable Ampacities of Insulated Conductors. In the NEC 310.16 for 6 AWG Wire there are three columns. 55 amps for the 60° column 65 A for the 75° and 75 A for the 90° column. So the actual wire itself is capable of handling 75 Amps. The problem lies within what degree rating the equipment That is feeding the wire is rated at. The breaker in this instance which is rated at 75° determines what column to use. So in this scenario # 6 AWG is good for 65 A. If all the equipment including the wire was rated at 90° that would change the game. Not all parts are created equal..;-)

Yep, this video covered a lot of material that other videos failed to mention. My Tesla Sales Advisor stated the WC could support 80 amps. I now know that he was referring to the Ver 2 WC. And I liked your explanation of using the white wire on ground bus bar.

I'm probably going to get some 6/3 romex. I was thinking of getting 3/2 but the wires are white and black, which would have made the install confusing to an electrician in the future and potentially unsafe. 6/3 also allows me the freedom of removing my WC and adding a 14-50 plug in the future if I move and take my WC with me. And there is plenty of space inside the WC to coil up the extra unused white wire.

Just did a WC install today. Used 25' of TTHN #4 and TTHN #8 ground (90c rated). Cost difference between #6 and #4 was .25 per foot. Not worth the $25 to have an upgrade path and lower fire risk; plus the #4 can be retrofitted w/ a sub-panel at some point and two wall connectors can be used at 30-38a each. The #4 90c rated wire can handle up to 95a; or 76a on a continuous load like EV charging.

[ritwekswetank]

Best Installation video. Precise and to the point.

[overdriver]

I just found your video to install my Tesla charger.. very good explanation of ground wire & neutral wire on seperate sub panel. Thank you!!

[jayte]

Thank you. Followed all your steps and I was able to install my wall connector successfully first attempt.

[jstevens]

your rational for using 6-2 on a 60 is interesting. I am not judging or criticizing. I just find it interesting how we all make our decisions. I have been doing elec for 40 years. And my justification is this. 55 amp breaker is not considered standard in the NEC hence you can go to the next standard which is 60. Hope i am not wrong. Otherwise I have been wrong for a hella long time. Anyway great video.
