- In this video, I demonstrate how I DIY hardwired my EV Charger (Electric Vehicle Supply Equipment or EVSE). There is a lot of information in this video, more than just the charger installation steps. I show you my tips and tricks throughout the project, how to get through challenges when things don’t go as planned, and how to build a PVC board box to protect the charging cord if you are mounting your charger between two garage doors. I also talk about what my preferred amperage to charge at is, so make sure you catch that at the end of this video. Please read the ***electrical disclaimer below, and understand it’s very dangerous working in your attic. One wrong step, and you will fall through your ceiling.

The comments are correct regarding wire selection. NM-B 6/2 is not rated for 48A continuous or a 60A breaker. Use 6-AWG THHN, TCER 6/2, or SER 4/3 for direct wire. What’s worse is that a lot of inspectors aren’t even catching this error. Good job on torquing the screws. Always torque twice! For those that use a NEMA 14-50, make sure to use a Heavy Duty outlet. The regular duty outlets aren’t rated for the continuous current and are melting down.
I address my choice of wire after the app setup in video. Thanks for sharing your info and watching!
I like your thinking about wire size - it’s better to have it and not need it than to need it and not have it
Exactly! Just incase someone behind me changes the settings, uses it, it is ready for its max capacity. Plus, I do use it at 48amps when I need it, been a year, 2 EVs use it everyday, works perfectly.
Also, you need to either have a lockout plate on the breaker, or add a lockout capable safety disconnect to the circuit. If you go with a NEMA 14-50 outlet, it needs to use a GFCI breaker.
I would personally recommend hardwiring your EVSE. Most modern EVSE have built-in GFCI protection. When the unit is hardwired, there is no need for a GFCI breaker. If the unit is installed with a plug with a GFCI breaker, there can and will be faulty trips. Thanks for sharing your info and watching!
Thanks for the super detailed video. I was wondering why running in the wires in the attic vs in another PVC pipe along the ceiling.
Thank you for watching and commenting! If I had no attic access, I would have just ran the conduit through the garage. But it was a lot easier for me, saved me steps, just to go straight up and use the attic since I used romex wire, and it was a pretty far run going all the way across the garage. Romex doesn’t need conduit in the attic. If I used individual THHN wire, it would have needed to be in conduit for the entire run, so I probably would have ran the conduit in the garage along the ceiling. Easier to work in garage vs hot attic. At some point, I’ll have a EV parked on the other side of garage, and when I install a second EVSE, I’ll do that for that side of my garage that has the load center because it’s a shorter run, so it will be easy to just use conduit the whole way. I hope this info helped!
That makes sense. If you don't mind me asking, what is the gun holder (that piece for the gun to rest off) made of? It looks so brittle. I hope it is metal and not plastic.
I really like the idea of the box to contain the cord. I will install mine on a wall next to my bikes and it will make such a box to keep the cord within its allocated space.
Hi again, it is made out of metal, very strong 💪🏼 the pvc board box was one of funnest parts of the project.
@@HomeDIYwithMartin good to know thanks.
Individual stranded THHN 6 awg wires might have been better than the 6-2 NM (Romex) cable you used. Probably less expensive. It has a higher temperature rating (90 C) and thus a higher current rating (recall 55 A in conduit, for 2 cond max). Much easier to pull thru conduit. I bought it by the foot recently at Lowes for another project (now planning for an EV charger). They had red, blk, wht, and grn stranded. Home Depot had only 2 colors by the foot in 6 awg, at higher price.
That will work great for you, enjoy your install. Thanks for watching!
I hate to break it to you, this does not meet code for a 48 amp continuous load. From Southwire - "Southwire® Romex® Brand SIMpull® NM-B (nonmetallic-sheathed) cable may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 60°C conductors) as specified in the National Electrical Code." So you should only charge at 40 amps. NM-B cable tightly bundles the conductors together and traps the heats in the cable assembly, which why you have to use 60C rating for ampacity. If it was 75C or higher copper THHN in conduit there is more space for the heat to dissipate and would meet code. All the EVSE manufacturers need to be more clear in the instructions and not depending people's (including residential electricians) knowing this often overlooked part of the NEC.
On every RUclips EV Charger install video there is a comment exactly like yours. And you are right, all the EVSE manufacturers need to be more clear with their instructions. I also think the wire manufacturers should actually sell wire rated, and then branded/packaged for EV charging. Not just for DIYers, but for electricians too. Hopefully you watched the whole video through but I do recommend charging at only 40amps. Although the 1% time I do not and everyone else that uses similar rated wire…just hasn’t experienced an issue. But I would just continue recommending charging at 40amps because it simply not necessarily with home charging to charge at your EVSE max output. The time savings in the middle of the night is minimal. My EV charges nightly on average for 2hrs or less with my daily driving at 40amps. So that’s what I leave it at and because of what you explained. But thank you for sharing your info and I would also recommend for everyone to consult with their electrician for their use case before installing a home EVSE/Charger.
Garage is considered a wet space. You cannot run Romex in conduit in a wet space. THHN/THNW 6g would is the correct choice. Exposed PVC conduit is subjeted to physical damage. Did you use scheudule 80 conduit and fittings?
I heavily researched and explored all my options before I started my EVSE install project. I can assure you, my choices have worked out great for my use case. Thanks for watching!
Enjoyed the video. Thanks for sharing
Thanks for watching and commenting! I appreciated that!
You shouldn't use the 48 amp setting. You've got Romex wire, you have to use the 60c rating, so that's 55 amps. Max continuous would be 44 amps. You should have finished the attic run and used THHN wire, then you could have used the 75c rating of 65amps. You would have been able to charge at 48 amps then.
I address this in the video (if you watch the whole thing) and on previous similar comments. Works great, 2 EVs charge daily. Thanks for watching!
Thanks for everything ❤❤❤❤❤❤❤❤

After watching a dozen or so of these types of videos, each of which has one or more comments about the wire gauge being incorrect, as well as comments from people whose electricians did it wrong, or even comments from supposed electricians getting it wrong, I am seriously wondering if there is a high likelihood
that I would get a incorrect install from an electrician at this point.
Go with Qmerit. They specialize in EV Charging installs. If you watch the part of my video after the app setup, I do talk about what I chose, and why. I put that part in there knowing I was going to get comments about my install :). Just about every single EVSE install video has similar comments. They just copy and paste.
Wife: Where is my lipstick with black cap on it?
He: Uh, I use it for DIY projects. Why?
Wife: I need it for dinner and I've changed my mind to donate it to you for your Do It Yourself something like that. I need to use it for special occasions.
He: Well honey, I'm sorry but I had to throw it away because I've use it all for several of my projects.
Wife: KABOOM! (Slap in his face so hard)
He: Whoa! My cheek feel stingy from your powerful hand! Why you do that to me?!
Wife: I forgot how expensive this lipstick was and honestly it's no longer exist, I really need it for that special occasion... I love that color!
He: Honey, I'm sorry but I thought you no longer need it and donated it to me for my project!
I'm just joking around, buddy LOL
By the way, you did nice job on this EV charger! :)
LOL :) Thanks for watching!
As previously mentioned, this will not pass inspection. First, you should always get a permit and inspection. Our utility offers installation cost rebate and requires a passed inspection (aside from just keeping people safe.) It is not just setting the charger to a max of 50 amps output but the 60amp breaker is too big for the wire type and needs to drop to 50. If I install an EVSE with a 60amp breaker to achieve 48 amps on the charger, I need to use either #4 romex or #6 thhn in conduit.
Read my previous reply to very similar comment. Thanks for watching!
Gas forever🤣
Depending on your age, you might be able to 😉
