Installing 220v/240v Outlets is Pretty Simple – New Shop Build Out

Installing 220v/240v Outlets is Pretty Simple – New Shop Build Out

Support what we do at
It’s time to install new 220v/240v outlets in the new shop. I’m not an electrician BUT I’ve done these outlets so many times I’ve lost count over the years. My friend, legendary pro skater and woodworker Chris Cole joined me to help get the job done. They are very easy to install for bigger, more powerful tools or if you need to put in a charger for your electric vehicle, tesla or EV. I walk you through the process step by step and show you how I approach safety around an electrical panel. For my outlets I used 2 pole, 20 amp breakers, 12 gauge stranded wire, 20 amp 240v outlets, twist lock 20 amp plugs, metal boxes, ground screws, ¾ in conduit and some drywall anchors. You should always follow local code and consult an electrician before attempting these your first time. Typically, unless you have long runs of wire you want to use 12 gauge for 20 amp, 10 gauge for 30 amp, 8 gauge for 40 amp and 6 gauge for 50 amp circuits.

    I really had to check to make sure like 3x that Chris Cole was actually in the video. I didn’t realize Chris was a woodworker whenever he’s not being a skateboarding legend. Awesome video!

    Here what’s wrong.
    If you can get 120v from a 3 phase panel. The panel is 120/208V panel.

    The max voltage at that plug if both leads are on the hots is 208v.

    Measuring hot to neutrals is not correct way to determine your phase voltage between hots.
    This means the motor is now under powered with voltage and drawing more current, which is not good for the motor

  8. thisIsSomeShite on March 18, 2023 at 7:25 am

    9:36 You think that’s 1/4"? I must need to get my eyes checked. Looks like way more to me.

  9. fotopdo on March 18, 2023 at 7:27 am

    I don’t think his description of 240 is correct, instead of two out of phase 120 waves, it’s a single sine wave twice as high. Also, 240 does not use a neutral because the neutral is a center tap from 240v transformer.
    US residential power is 240, the neutral to the center tap of the transformer on the electric pole allows 120v circuits. It’s a bit confusing because most circuits are 120

  10. MemeZilla on March 18, 2023 at 7:28 am

    Wow, that was interesting.

    But,I think Chris spoke way too much throughout that whole presentation 🙄😒, so maybe next time limit his input please🤪🤪🤣🤣

  13. David Shaper on March 18, 2023 at 7:29 am

    My shop has three 240 outlets on the same breaker. Don’t tell anyone.

  14. Martin Woodworking on March 18, 2023 at 7:29 am

    This is my next step after finishing the divider walls in my shop

  15. Leonardo Divinci on March 18, 2023 at 7:29 am

    Why in the world are you using stranded wire? All should be solid wire! Just saying.

  16. John Hawkinson on March 18, 2023 at 7:33 am

    This video is improperly confuses 208V 3-phase service (what Jonathan has) with 240V single-phase service (found in most residential locations in North America). That’s bad because running a 240V motor on 208V is giving it 13% less voltage, which will often (depending on type of motor) mean not getting the torque or power that the device is designed for. (On the other hand, the opposite direction would be far worse: running a 208V motor on 240V can overheat it or destroy the motor, although it depends). 208V and 240V devices are not interchangeable, although often they will work just fine; but when they don’t it’s an expensive mistake. Also, it’s usually accepted that there may be 5-10% variation in line voltage, so a 240V device ought to run on 216V–264V, but you can still be pressing your luck. (Similarly, devices actually labelled 220V or 230V, whether from the European market or otherwise, encompass both 208V and 240V in their +/- 10% range. But it’s not great to rely on this)

    The asides about "code may vary" are also relatively misleading. In the US, the National Electric Code is near universal. Different jurisdictions have adopted different yearly versions of the code, with local amendments, but the bare bones are the same everywhere, and things like wire gauge and grounding requirements are not questions of local variation. Making it sound like they are breeds confusion.

  17. Rich Sparkman on March 18, 2023 at 7:36 am

    Good way to die get a professional would you get an electrician to build you a cabinet

  18. Daniel Myrenne on March 18, 2023 at 7:36 am

    Do all breakers and panels look like this in the US? I have to admit I’m a little shocked, how easy you can electrocute yourself because of missing plastic-shields.
    I don’t wanna say, its not possible to do so in germany, but it seems so much easier with the equipment you are provided with.
    Stay save! I like your style and videos to much 😀

  19. P L on March 18, 2023 at 7:40 am

    Isn’t it 208V when using two phases of a three phase panel?

  20. Brandon Somerville on March 18, 2023 at 7:41 am

    I’ve read multiple sources saying you can have more than one outlets on one circuit. Is that true you can only have one outlet per breaker?

  21. sam neuman on March 18, 2023 at 7:42 am

    Just to point out, in a 3phase commercial panel with bolt down breakers, you need to install only bolt down breakers not snap in. Fyi the take off on 3/4" emt is 6".

  22. Clayton Shaffer on March 18, 2023 at 7:43 am

    @9:20 " you can not screw this up"

    dude you know this is the internet right?

  23. BariumCobaltNitrog3n on March 18, 2023 at 7:43 am

    Couple small things, with stranded wire you should use crimp-on terminals if the receptacle doesn’t have clamps and on the ground wire to the box. Also color of wire does matter at the panel, breakers top to bottom go black red blue on a 3 phase like yours. I think you wanted to use red and blue, but that’s just ocd talking. On the receptacle, it doesn’t matter. A good idea in a metal box is to put tape around the receptacle covering the screw terminals so if it comes loose and touches the box you get no bzzt. And lube, no. Bushings on the pipe connections inside the box, yes. Always hire an electrician to check your work.

  24. Gary Dargan on March 18, 2023 at 7:44 am

    Where I am 220/240v is standard. When we need more power we use 415v.

  25. Blake Pizzey on March 18, 2023 at 7:46 am

    I was so confused… I was thinking, is it just me or is that Chris Cole!? Very cool. Time to go play some Tony Hawks Pro Skater 5.

  26. Rebel7469 on March 18, 2023 at 7:46 am

    Something to keep in mind. Start up for all inductive loads are 5 times plate rating. So your 13 A is run amperage start up is 13 x 5 = 45 A

  27. 4321 Woodworking on March 18, 2023 at 7:50 am

    Was there a reason for the stranded wire over say using solid wire for the hots? We used solid in my shop but the guy helping me I trust as he sold the electrical stuff to farms and brought it all. Also to note the conduit bender makes an awesome clean looking bend and installation BUT for the average homeowner tackling something like this I always just bought the pre-bent pieces and connected them. I know it’s not as clean of a look and maybe in the long run been cheaper to buy the bender I’m not sure. It’s one of them I always think for a one time job why buy the $40 tool (1/2" bender) when a couple of 90s are $6. Just wanted to throw that out there as another option is all for some.

  28. Ross Wines on March 18, 2023 at 7:55 am

    Move to Australia!! We have had 230VAC for decades. Along with decimal currency and drive on the left side of the road. 😉

  29. Douglas Boyle on March 18, 2023 at 7:57 am

    "Before reaching into a panel you really want to make sure this thing is off. I have quadruple checked and I have checked again"
    As a former electrician can confirm, people do stupid things on job sites.

  30. Mike Curtis on March 18, 2023 at 7:57 am

    Kinda funny watching someone who works with measurements all day day he’s gonna strip about 1/4 inch of wire, and then proceed to strip at least 1/2 to 5/8 inch of insulation, lol

  31. Nick Larson on March 18, 2023 at 7:59 am

    Was scrolling through and thought, "that looks like Chris Cole with JKM". Clicked on it and was super surprised. I had no idea he was into woodworking. What a legend.

  32. mike on March 18, 2023 at 7:59 am

    I don’t think there’s any code against having multiple outlets on a 240v breaker. In fact, you can buy NEMA 6-20R duplex receptacles anywhere

  33. Andy Abraham on March 18, 2023 at 8:00 am

    Sorry mate, I do wish you could do Metric as well. Happy days KM.

  36. Brent Fowler on March 18, 2023 at 8:03 am

    Jonathan, I think of you like an older brother that woodworks. You know something like that, this is already starting to sound weird. All I’m trying to say is that I respect you, and look up to you. Some of which is because of where you came from, working as a bartender. And now you’re producing some of the finest, Dovetrail joins on YouTube, dare I say the world!! Anyhow, Jesus, I can talk. And take forever doing it. Without there even being any importance to what the heck I’m saying.. Alright so, everything I’ve just said is simply to say that I’m not making fun of you. Or trying to be an ASS-istant!! (ASS-istant= donkey in a hurry! Lol) I’m also not trying to be disrespectful in any sense of the word. That just really made me laugh, "230v that between 220 and 240!" Oh really?! Wow.. I had no clue.. lol I’m sorry man. (Really not trying to be that guy on the other side of the keyboard, being a D-canoe.) And, I’ve also never tried to shoot video of myself woodworking, doing electrical, or anything else for that matter!! So there’s that too.. Alright so, great video as usual my friend. Nicely done, btw if you end up needing a hand tool for doing a project whether being electrical, or anything else. You should check out (if you haven’t already.) Knipex. They make the best hand tools that I’ve used other then USA made, quality tools of course. Talk, talk, talk… Lol sorry about the novel.. Take care

  37. Robert Bamford on March 18, 2023 at 8:04 am

    Oy! Braver than I am. As you suggested, I’ll do the conduit, plugs and wire with lots of excess on the panel end. But when it comes to the panel, time for a licensed pro (who I actually consulted before I started).

  38. Zamboni on March 18, 2023 at 8:04 am

    I am no electrician, but should you not be using solid wire?

  39. Wolfman on March 18, 2023 at 8:07 am


  40. Hank Pikuni on March 18, 2023 at 8:09 am

    8:56 LOL

  41. Matthew on March 18, 2023 at 8:10 am

    LOL "impossible to screw up"…. back when I was scared of electrical I paid an obscene amount to a licensed electrician to install two 240V outlets in my garage, each on their own circuit. Dude put one wire from each breaker on each outlet – so the outlets tested fine, but if one of the two breakers was off, neither outlet would work. I bought a book with a lot of pictures in it after that experience and I haven’t paid for electrical since.

  42. Alexander Reid on March 18, 2023 at 8:10 am

    Hi Johnathon, I really enjoy most your videos EXCEPT THIS ONE. I am an electrical contractor here in Australia and having lost work associates to electrocution I can’t over emphasise how dangerous electricity is, "you don’t get a second bite of the cherry with 240v". One work associate who worked as an equipment assembler in a factory purchased all of the parts to carry out his own wiring at his home, when he didn’t emerge from under the his house his son went under to tell him his lunch was ready but found him still clutching the LIVE cable that he evidently thought was isolated but drastically wasn’,t no second chance there. I realise that codes are different in every country but as your videos are watched world wide I couldn’t watch your video without grimacing in despair as to how many mistakes there are for Australian codes for instance. PLEASE, PLEASE leave electrical work to fully licensed personal, life is far to precious.

  43. JulienB on March 18, 2023 at 8:12 am

    That is Chris motherfucking Cole.

  44. robleake on March 18, 2023 at 8:12 am

    US should just go 240V for everything, so many advantages.

  45. Allen Curry on March 18, 2023 at 8:13 am

    Had too much coffee? The first 7 minutes or so, you spoke so fast it was difficult to follow you. Now I imagine you were rushing to keep the video time as short as possible. I think I’ll rerun that part of the video at 1/2 or 3/4 speed so I have time to grasp the concepts and suggestions. Thanks for taking the time to post this video, electrical info from someone I can trust.

  46. JHans on March 18, 2023 at 8:15 am

    Good video. Thanks. I have some safety comments from experience working at an electric utility. Be aware that finger-pointing at open and energized electrical panels can lead to a deadly arc flash. 120/240 volt single-phase and 120/208 volt three-phase can kill you. In addition, face shields and low-voltage gloves should be used until the panel has been confirmed to be de-energized.

  47. Oh Asis on March 18, 2023 at 8:15 am

    Dunno why I watched this so thoroughly – I live in a part of the world that has 240 as standard.

  48. Steve Cobain on March 18, 2023 at 8:16 am

    Holy shit what a crossover. Chris Cole one of the greatest street skaters! Awesome to know that he loves this shit too.
