    Yes at 3:50 you say blk and white are 240. The white is on neutral bar right?????????

    I have to stop right now I have electric furnace in garage on 60 amp breaker. Im replacing it with a hanging 240 volt comfort zone heater and watch you tube videos they say the black and white are both hot especially if you run the white off breaker. but mine is 240 volts has L1 L2 and L3 L! and L3 both say Hot wires and no neutral is needed. But I have 4 wires the red,blk,white common and clear grd. L2 has absolutely nothing and these guys only one showed he took the white and bare grd together for safety? Right??? It does have a bolthead with Grd markings the 3 lines so I will put red to l1 black to l3 white to ground lug and the bare copper wire to a suitable ground to case. I know thats right. And you can get 240 volts with 2 wires 1 from ea 120 volts!!!

    Good video! You had my attention with the electrical lesson, now I want to know more about the brewing

    Stupid and unhelpful

    Very informative video. Question is 10AWG 2wires (10/2) for 240 volts, how can I use 10/2 wire for 120 volt bulb?

  7. Zune on March 23, 2022 at 6:11 pm

    In Europe we use 3 fase 400v 16A 2.5 sq mm cable or 1 or 2 fases 230v 10A 1.5 sq mm cable + neutral and earth.

    Ok here is a question, maybe related to the AK 47 rifle, but regarding the 3 prong wire plugging into the wall outlet. i get the 120 vs 240 and why we stayed 120 while Europe and Asia went 240, but remember the BlackBerry phones where you could swap plug adapters and slide the voltage switch? Why can’t all countries adopt the same 3 prong wall plug socket design? Just put s slider switch on mobile devices for voltages, but the prongs and sockets they plug into just be the same?

    Ak-47 relativity. Invasion. Many of the Eastern communist bloc countries did not trust the Soviets to not invade them and while agreeing on the same standard "design" of the rifles while taking the same ammo and 30 round mag, they instead altered the rest of the rifles dimensions.
    So the pistons for example are the same design, however the diameter or length was altered just a little so the soviets could for example not grab Hungarian AK’S for parts to resupply the Soviets rifles so they they were stuck with their own supply lines and could not turn the Hungarian rifles against the Hungarians so easily. See Hungarian "AK" the AMD65 vs AK47 for an example.

    In that respect, is that a possible reason some countries designed their wall outlets to connect differently over there while carrying the same work load? They could not trust some neighbors invading so they cannot just plug their equipment into an enemies lines for power thus keeping their sockets the same with allies but different than potential enemies?

    Just curious. After all the Soviet "Hind" gunship IS DESIGNED on purpose to work on all Soviet AND SIMULTANEOUSLY work on all American ground power supplies for all its systems without modifying its connectors, but our aircraft’s electrical systems cannot work on their airport ground electrical systems only ours and any allied countries using our systems.

    In my country the voltage between the phase and the neutral conductor is 230V +/- 10% and between any two phases it is 400V. Every other house has a three-phase connection.

  13. Mark TheUnitedStatesCitezen on March 23, 2022 at 6:15 pm

    Thank you – I have a 5 KVA 230v Pure Sine Wave Inverter charge controller 230v x 1 “ I’m looking to wire this 2 leg at 115v safety the Amperage at 3 KW 76A is what I use every day normally, I’ve seen to wrap both the red & a black wire around the 1 hot wire coming out of the inverter to wire into a 100A double pole breaker that’s dedicated to this only in my breaker box and I have the Mose Automatic Transfer Switch and a test I saw it works with no feed back . Does this look correct ?

  14. Martin P on March 23, 2022 at 6:16 pm

    U teach?? Classes??

  15. Capt. Taylor on March 23, 2022 at 6:17 pm

    This is what I was looking for. Simple straightforward explanation.

  16. Sean Weeks on March 23, 2022 at 6:18 pm

    Hypothetically, if the buzzer or the clock (the 120v draw) would trip a 120v breaker, then what would happen if it’s wired to the two pole 240v breaker?

  17. The Camping Trucker on March 23, 2022 at 6:18 pm

    Yesss Sir!!!! Thank you for the lesson you helped a lot!! Thanks again!

  18. midnight Rampage on March 23, 2022 at 6:19 pm

    Best explanation on YouTube,period. Thank you.

  19. Europea Madrid Cafe Bar Tapas on March 23, 2022 at 6:19 pm

    Hi
    I bring with me from Europe hair dryer and its 240 V, but here in US its 120 V.
    what i shall do to let it work Please.
    thank you

  20. cslloyd1 on March 23, 2022 at 6:21 pm

    At 2:55 you say "add two peaks together to get 240v". Not to be pedantic, but you don’t add two peaks because they are occurring at different times (separate by 120th of a second). I think you *subtract* the two waves AT THE SAME POINT IN TIME to get the voltage difference. Since one wave’s peak is positive the other (trough) is negative, you’ve got +120v – (-120v) = +240V.

  21. Mitch Mabee on March 23, 2022 at 6:22 pm

    I desperately need help wiring my welder. I wired my 220 dryer no problem. Because it was two 110’s and a ground. NO NEUTRAL.
    The problem is this old Miller Thunderbolt stick welder has a power cord with a black wire, white wire and green. SO I’M SCREWED. Apparently this welder expects me to have 240 power that incorporates a white neutral wire. What do I do?

  22. Tommy Smith on March 23, 2022 at 6:22 pm

    Has to be one of the best videos I have watched on 120v vs 240v. Great job on explaining.

  23. Relaxation Tv on March 23, 2022 at 6:23 pm

    I have two 115v power inverters. I want to wire a 240v coming off them but I don’t want to fry my inverters. Is there something I can do to make 240 safely?

  24. Sudu සුදු koka කොකා on March 23, 2022 at 6:26 pm

    Great explanation. can you please explain the 208V too.

  25. Jason Silva on March 23, 2022 at 6:26 pm

    I could use a little help I would like to know how a 2pole (2-110v legs) 240 50/60hz motor works on single pole 230 50hz 1 neutral and one 230v leg
    And yes I get lower RPMs
    Also can I wire a 4wire 110v motor to 240v Ithaca a start capacitor rated for 300v no wir diagram I can’t tell if it’s brushless if it’s not will it work out of phase and please school me

  26. G. D. on March 23, 2022 at 6:27 pm

    Heater says 50 amp so i may rob my stick welder breaker its 50 amp. Like 60 but says 42 amp draw so it would really have to get something very hot to kick 60!!!

  27. Matt Hauk on March 23, 2022 at 6:27 pm

    Thnx George!

  28. mrrmsfucker on March 23, 2022 at 6:28 pm

    3:29 your welcome.

  29. X FIRE on March 23, 2022 at 6:28 pm

    Excellent info

  30. John W on March 23, 2022 at 6:29 pm

    Great Video! Enjoyed watching! Also examples of common 3 wire 240 volt devices will include air compressors, welders,plasma torches etc.

  31. Sword Fish on March 23, 2022 at 6:31 pm

    Good video explanation. What will happen if I replace a 240v three phase 1/2hp servo motor (that provides power to my sewing machine via a drive pulley) with a 1/2hp 110v single phase motor? Can I damage any electrical panels that are wired in between the original motor and the sewing machine? Any chance I can do any damage to my wall outlet wiring?

  32. DaddyDawg on March 23, 2022 at 6:31 pm

    I have several Pool Motors for an Outside pool designed to be wired for 120V or 240V. Since these motors actually run for hours at a time (8+).. is there an advantage wiring for one as opposed to the other.

    Does One voltage put more wear and tear or use more electricity (Higher $$ Bill) than the other? I have never seen an answer to this. Currently.. all the Motors are wired for 110V.

    Thanks to anyone for a response.

  33. Macster on March 23, 2022 at 6:31 pm

    I noticed my receptacles only have 110-112v, so I checked the breaker box and I only get 112v. Aren’t I supposed to get at least 120v?
    Im in the USA.

  34. G. D. on March 23, 2022 at 6:32 pm

    Thank you question answered 240 does not require a ground. But what if power companies loose a ground which does happen??? Just glad to hear that Im using the 4 wire as its already where I need it but Im on 60 amp breaker about 40 ft wire 6/4 I guess I just dont want getting shocked.

  35. David D on March 23, 2022 at 6:33 pm

    120/208 volts AC is common in America as well. Some utilities in metro areas use 3 phase banks hooked in a Y configuration to supply single phase loads to residential, which is done to balance load between the 3 phases.

  36. Aztec Warrior on March 23, 2022 at 6:34 pm

    How on earth you trying to explain all of this whiteout showing how it starts at the breaker box. You made this way more confusing. And I have worked with 240 since I was 18. Now 45. You gave me a head ache.

  37. Tadas Strikauskas on March 23, 2022 at 6:35 pm

    Thanks. As an european I will be able to tell other fellows that US also has 220V.

  38. Hiking Bears on March 23, 2022 at 6:35 pm

    Perfectly said! 👏🏽

  39. Charity Heckler on March 23, 2022 at 6:36 pm

    Thank you for this! This really was much simpler than other videos made it out to be!

  40. GH1618 on March 23, 2022 at 6:37 pm

    I would not use white wire for anything but a neutral.

  41. Shane Wells on March 23, 2022 at 6:39 pm

    Thanks

  42. Robert Luciano on March 23, 2022 at 6:42 pm

    When I measure a 240 volt circuit, on either one of the legs, does that mean the amperage draw is doubled of that which I had measured? Sorry for the dumb question…

  43. Martin Nunez on March 23, 2022 at 6:43 pm

    Thank you, George…

  44. N Mokonya on March 23, 2022 at 6:44 pm

    Thanks for the great explanation.
    But hope you and your viewers understand that all your explanation is only limited to North America.
    Europe and Africa have a completely different system (240v) which will need a step down for you to run any of your North american appliances.

  45. Trucker247 on March 23, 2022 at 6:45 pm

    I need a 120v outlet at my 240v well. Provided the amperage is acceptable can I tap an outlet? It’s getting cold, and I want to run a small heater.

  46. steven schwichtenberg on March 23, 2022 at 6:48 pm

    I am wiring my generator 4 wire 220 volt 30 amp to a 120 volt 30 amp connector. To run a 220 volt 30 amp heater. I plan to use only 3 wire 10 guage to the generator. I see no reason that there would be a problem using the 120 volt outlet, even though it is only rated for 120 volt 30 amps. Am I wrong?

  47. randy johnson on March 23, 2022 at 6:49 pm

    Just had a lightbulb moment lol👍

  49. Elite Irrigation Repair LLC on March 23, 2022 at 6:51 pm

    Watching this video for education mainly, but you said 240 had its own neutral. I missed how, but could you explain?
