220 Volt Plug Receptacles Configurations

 These outlets are the ones you’re most likely have in your house.

Ok, so let’s talk about the types of outlets you’ll find in your house. For the most part, you are going to see 120 volts, 15 amp, and 20 amp. And 220 2 wire, 3 wire, and four wire types.

Please remember not all 220-volt outlets use a neutral (white) wire. To give you a general idea, let’s say you just bought an air compressor from Home Depot. It requires 220 volts but the plug only has three prongs. You’ll have the two that look alike and will be the two separate hots and other round looking on would be the ground. And of course, more than likely it would be 20 amp.

Wire Connections for X Y W 240 Volt Receptacle Dryer Outlets The Black Wire attaches to Outlet Terminal X The Red Wire attaches to Outlet Terminal Y The White Neutral or Green wire or Ground wire attaches to Outlet Terminal W


Commonly known as a dryer outlet. Of course used for a clothes dryer. This would be used in a wall box with a cover plate (flush mount)

220 volt 50 amp outlets

50 Amp 220v 4 wire


In a house, these would be considered the big boy. You’ll find one of these in newer homes for a stove oven combo. This is a 4 wire outlet. See my video on how to install one of these.This is 50 amp 220 4 wire. Better know as a stove or oven outlet Keep in mind, although you might have an oven, dryer, stove or whatever. It may not have an outlet at all. It could be hard wired into the appliance. And that’s fine, lot’s of bigger commercial appliances are known to be wired that way.Tip… Red is hot (110 volts) black is also hot (110 volts) = 220 volts. White is neutral and is the returned path back to the transformer on the road. The ground is just that. Ground to the each and is always used on anything electric. Unless of course, your house is very old in which case should be updated just for pure safety.

  1. It does not make a difference at all. I would really check your wire for breakers, or the way you’re connecting it to the breaker.

  2. Question, Ive installed several 20 amp 220v outlets and never had any issues. Today i installed one, and when I flipped the breaker there was a quick spark in the panel and the breaker popped… I swapped the 2 hots (white/black, using 12/2) on the breaker and it was fine…. Ive never worried about the order of Hot leads on a simple 220 circuit before? Can they be wired backwards? The run was only about 30 FT, i check the cable for possible shorts and did not find any.

  3. Yes of course that’s fine. Just make sure you connect the correct wires correctly. Hot with hot, ground with ground

  4. This comment is edited.

    I have a question pertaining to a circuit’s amperage. I have a dedicated 240v/50amp circuit for a car charger. The recent PHEV we leased has the capability of accepting standard 120v or 240v input however the plug configuration is a 240v/20amp design. Can I simply rewire the receptacle to match the 240v car plug or will this be dangerous?

  5. Assuming you’re in the US or Canada. You’re talking about two very different things here.
    Watch this video. This is part of what you’re talking about. But it’s for 120v

  6. Hello, I have a question about a 20 Amp 220 Volt outlet. I have one and need to wire to electric box. It was connected to a double pole 20amp square D breaker. However, I was told that I need a GFI or some sort of protection breaker. I purchased a 2 pole GFCI Breaker but it has a neutral connection. I do not have one on the outlet, so I am not sure what I should use. Thanks in advance!

  7. A NEMA 2-20 is just a 120 20 amp outlet. What is it you’re trying to do?

  8. Hello!
    I have just moved into a new apartment where I discovered a Nema 2-20 outlet in a room that has no other outlets. I was wondering if you could recommend some kind of adapter (although I have searched at length for one with no results), or if I should replace the plug.
    Thank you for your time!

  9. The NEMA-6-15 is what I use in all my shop equipment including my table saw. Either one will work just fine.

  10. Thanks. I am having a sub panel installed in my shed, as you describe. And that sub panel will have two 20amp circuits. I will use one of these two 20 amp circuits for my 220v table saw. At 220v, my table saw will draw 7.5 amps.

    I’m trying to figure out what kind of outlet I need to Install in my shed for the 220 table saw. Does it need to be NEMA 6-20 or NEMA 6-15?
    When I look at the Table saw owners manual, it suggests I add a NEMA 6-15 Plug to the end of the power cord.

    I wanted to get your thoughts. Do should I add a 6-15 outlet in shed and 6-15 plug to the table saw’s power cord. OR should I add a 6-20 outlet in the shed and a 6-20 plug to the table saw’s power cord.

    Many thanks!

  11. What you’re needing is a subpanel installed in your shed. Using 1 1/4″ conduit to the shed. #8 wire. Two hots, neutral and a ground with a seperate ground rod at the shed to the sub-panel. A 20 amp 220 plug is what you need. What my how to install a 220 outlet for the outlet you’ll want.

  12. Hi. I’m having a shed built with 40 amps being run to it. I’m going to have two separate 20 amp circuits (one for 110, for
    lights…..and the other for 220 for power tools).
    I need to convert my table saw from, 110 to 220. The instructors manual stated I need to use a NEMA 6-15 blue and
    receptacle. However, from your write up it seems I should be using a NEMA 6-20.

    I guess I need to know what outlet to be installed in the shed. And what plug I need to put on the end of my saw’s power cord.
    Many thanks!

  13. Sounds like you only have one hot leg being used. Watch this video. I have others on here as well.

  14. Just installed a new 3 wire 220 stove outlet
    But,now my stove only partially works.
    Burners come on but oven and digital clock and panel lights do not. ???

  15. Ok, please watch my videos on installing a 220 volt outlet. Everything will much clearer for you. There is no such thing as a double stack. It’s two pole. Meaning that each leg is going to grab a separate hot from the panel, each one being 120 volts =220/240 volts. Your black is 120, now your white will become 120 each.

  16. Ok. I have an appliance that is requiring 220. The plug is 3 wire, white, black, and ground. I have a 60amp double stack available and ran 10/3 to a receptacle that has 3 wire set up. My black is on just one side of the 60 double stack. Matched the wires going into the receptacle with plug. Powers up fine, but not getting the volts I need. Is this because I am not getting 220 from the double stack by only using one side. Should I replace the double stack 60 with a single stack 30? Let me be clear, I am not an electrician but handy. I have hooked up a 50 amp and 30 amp rv plugs with no problem. Thank you all

  17. Yes by all means. That’s what all that means. Just a little confusing that’s all.

  18. I’m in the process of replacing an older electric range that the tag says it’s a 120/240VAC three wire hard wire connection. The circuit panel for the outlet has a double breaker 120/240VAC 50 Amp. The oven I want to install says it requires a 220VAC outlet rated for 40 Amps. Can I install a 220VAC outlet on a circuit that says it’s a 120/240VAC?

  19. No, very different of I remember correctly

  20. Yes it will, it’s under the amperage max rating of your coffee machine. However, if there was an issue with it the breaker wont trip until it’s limit of 40 amps.

  21. Hi

    So can I plug in NEMA 1-15 regular plug in to a NEMA 2-20 (killark) receptacle?

    Hello sir,
    I just checked what type of breaker i have and found its 240v-40amp.
    And i just got the cable and want to ask to make sure.
    The coffee machine i have is labeled as 240v-30amp.
    Will it work fine on 240v-40amp.
    Thank you in advance.


  23. It’s over kill, but hey whatever makes the connections and does it right is fine. All of my shop equipment is 20amp with 20 amp plugs.

  24. Hello. So I have a 220v/50a plug in my garage. The one you called “big boy”. I recently bought a bandsaw that is 10a at 220v. So I bought a plug that matches the 220v outlet and wired it. It works fine and I have no issues. Should I have done this? Also, I want to buy a dust collector that is a 240v/9a. Can I replace the plug to the dust collector to match the 220v/50a outlet?

    Ok, thank you.

  26. The only un-safe part is that if something goes wrong with the coffee maker the breaker won’t trip until it reaches 50 amps. If anything I would at least replace the breaker to a 30 amp.

    I have a coffee machine that has
    (l6-30) plug and listed to work on 240v-30A.
    And I have a wall outlet that written on it 240v- 50A (10-50).
    I find online an adapter l6-30 female 10-50 male, which will work in my case.
    But will be safe for 240v 30A machine to work on outlet 240v 50A.
    Thank you.

  28. No not that I know about. I would just change the outlet really.

  29. I hope you can help. I just bought a 60 gallon air compressor which has a plug that is either Nema 10-20 or Nema 10-50. The outlet in my building is a Nema 6-50. Is there an adapter that will allow me to plug in my air compressor without rewiring?

  30. hello great site, I have a 60 gal air compressor that takes 220v No plug, it was hard wired in. I want to use my generator to power it. my generator has a 120/240 outlet NEMA L14-20R type receptacle on it any ideas of the best way to do this?

  31. I understand what you’re saying, but the wiring configuration is very different between the two. So no. You’ll want to change both the outlet and plug for 220 volts.

  32. I was wondering if I could use a 20a 125v outlet for 220v? The max amps I would be running would be 7.5 amps. The problem I have is the male plug on the cord I’m using, the equipment can run on 220v or 110v, the equipment I’m using runs more efficiently on 220v.


  33. Just a question of terminology. I have an extension cord. One end–the plug–is OK. The other end (into which one would insert a plug) is damaged and needs to be replaced. But for the life of me I cannot figure out what that item is called. Receptacle, outlet, socket? Please tell me what to call it.

  34. No, you’ll need either a 40 or 50 wire and plug. Or just hard wire to the stove. It’s the wire and the breaker you’ll want to pay attention to.

  35. I have an oven (not too old: 15 years old) which has the same plug as the one that fits into the 220volt 50 amp outlet, but the house is old and I bet that doesn’t have 4 wires. At the wall, I have an outlet similar to the one listed under the 220 volt 30 amp.

    Can I change either the outlet or the plug to match?

  36. This comment is edited.

    I have a generator with a NEMA L14-30-R 30A 125/250volt receptacle and it has 4 curved plugs on it and one is “L” shaped I want to know if I can use a 220amp 20volt like the first picture here. I could not find a picture of the 125/250v 4 plug in any of the NEMA straight blade charts on here. I went to the NEMA site and found it on the curved blades charts but it has no information on whether I can change this to the 220v 20amp straight receptacle.
    I have pictures but I don’t know how to put them on here.

    Thank you for any help!

  37. very good tec. reading n videos keep up t good imformation. linda

  38. This all depends on what you’re intending to hook up.

  39. Don’t know if anyone is monitoring this website, but I would like to know WHICH 220v plug configuration to install in my garage, not knowing what receptacle I will need in the future?

  40. Home Depot or any electrical supply.

    Looking for a receptacle for a new AC. 25amp 240 avc. 2 blade W a round ground. Where can I pick one up at?

  42. I did not realize that but rest assure I’m working on that right now. And thank you so much for letting me know.

  43. The picture that accompanies the link to this article does not appear anywhere in the article. It had an outlet like mine that I am trying to find out more about, but alas there was no info on the type of outlet depicted in the link. Where do they pull these images from if not the article itself?!

  44. Either way would be fine. I may chose to change the outlet.

  45. Stove plug is 3 prong wall plug there is 4. I have a 3 prong wall plug can I just change out the covers or do I need to change the whole thing?

  46. I’m sure it’s 220. But they are not all the same as you now know. The easiest way would be to just replace the plug on the dryer. Send me some pictures if you like.

  47. Hi my daughter just moved into her new home three days ago. She has purchased a three prong dryer. Problem is the outlet is not made for that. It’s a weird outlet 220? frustrated what to do?

  48. If it really is 220 volt then no. You need 220. But really a 220 volt TV?

  49. You would want to cut out a square large enough to where the sheetrock is solid and then use one of my how to repair a large hole in sheetrock.

  50. Have a hole in my bathroom ceiling that started out the size of a dime…now the size of my fist. This was caused by a leaky roof which has since been repaired however how to I patch such a large hole as the surrounding plaster seems brittle and weak! Unsure if it can accommodate a plaster screen patch! Help!

  51. Just found a Sony tv but was not aware that it is 220 volts! Can I just buy an adapter and plug this in to a standard USA outlet? Or do I need to have the outlet changed to accommodate the 220 volts?

  52. Hey Rick. Go to the store and buy you three prong plug. Read the numbers on the outlet. Should be like Nema-??? three prong means 3 hots and neutral. For 110 you’ll only need one of the two hots and the neutral.

  53. Hello I purchased a used generator and it only has 2 220v outlets they look 3 curved prongs its a elemax sk2900dx the guy I bought it from said I need a step down plug but it was a sight unseen sale can u please help me I want to use it to run 110 items like fans lights etc ive looked everywhere for help i dont have alot of money and cant afford any mistakes any help would be great the generator says 220v only so lost thanks Rick

  54. So, use the existing 110V circuit and change out the single plug outlet to a dual plug outlet? Or are you saying to run another line from the breaker box?

  55. Thank you for the various 220v receptacle diagrams….. A pain trying to modify the plugs and receptacles from the welder and plasma cutter to the house and also be compatible with a generator.

  56. Really I would just bring another 110 volt outlet to the dryer. Playing with the existing 220 would not be wise.

  57. I just bought a new home, and the washer and dryer needed to be replaced. We checked the back of the dryer prior to purchase to confirm there was a gas line (old one was electric on a 220V line). What I missed, is that there was only one 110V receptacle on the circuit in the area behind the washer and dryer. I have my dryer hooked up fine, with the exception that I have a temporary extension chord running to a nearby outlet.

    So, im trying to look into converting the 220 to 110 … or maybe change out the single 110 to a double 110 receptacle GFCI.

    Any guidance on changing to the 220 receptacle to a 110V for the dryer? Or, would you recommend leaving it alone and changing the 110 (with one receptacle) to a 110 with 2 places to plug in?

    FYI – I checked the rating on the washer and dryer, they are 10A for the washer and 6A for the dryer … so I think a combined 16A should be good on the 20A circuit if I decided to plug in both into the existing 110 (after adding the 2nd plug to it).

    My first thought was to change the 220 to 110 … any guidance you can provide?

  58. Yes if your new AC is really a 30 amp than you will need to change the breaker and wire. Otherwise you will have big time issues. Check the amp ratings on the unit just to make sure.

  59. A whole box or just the cover with the outlet?

  60. I bought a 220 box to fit my dryer plug…How do I swap them out?

  61. I just bought an Air conditioner that has a 230 volt 30 amp plug on it. My old failed ac unit has a 220 15 amp outlet for it. All though similar the 30 amp plug is a lot bigger. Can I put a different outlet in to accept the 30 amp plug or is it a lot more than that?

  62. 20 million views and you’re the first one to ever say that. I’ll keep that in mind, thank you.

  63. In your videos, you talk too fast for me to follow and kind of mush some of your words together. Rather than “laid-back” I’d prefer professional.

  64. use a twin pole switch. This will have 4 screws / connections not including the ground.

  65. Hi, I have a 3/4 HP Water pump set a 220 by the lake to feed my cottage.Currently the pump is wired directly to my panel.I would like to put in a on/off switch in my Bunkie adjacent to the pump.Are there considerations for what type of 220 switch and receptacle?

  66. I did not know that 220 outlets/cords have different type of configurations. I bought a 24 inch electric stove for my tiny kitchen. I was so excited to finally have an oven and the price was perfect. But alas, the cord has a different shape then the outlet even though both are 220. Are adaptor plugs available in these kinds of situations and is it safe to use an adaptor plug? No matter how cute the stove, I prefer not to burn my house down. 😛 Thanks so much.

  67. You say nothing about your shop and how many outlet you want. So I have no idea what to tell you.. Need more info

  68. I am setting my garage up as a small woodworking shop. Many of the tools I am looking to add to my shop are wired for 220. How many circuits / 220 outlets do I need. I have 4 duplex 110 outlets previously added.

  69. Dryer is dead. Circuit is not tripped. Checked outlet and have hot indications at 2 of the 3 prongs. Is this normal? Trying to eliminate issues before calling for repairs.

  70. Can you put two 220 plugs on one wire

  71. Thank you, got the right stuff today, an the 10/2 wire.

  72. You will need a 10 gauge wire.

  73. What size wire to use for a 220/30amp outlet, I have 12 g is that fine?

  74. Your dryer should be a 220 30amp. You should need to change the outlet or the power on your dryer.

  75. Hi, I just moved into a house that has a 4 wire plug like the ‘big boy’ you show here. My dryer has the regular 220 20amp plug. Do I need an adapter or to convert the whole recepticle and run a lower amp connection?

  76. Thank You very much for your vids and info on your website. It helped me to safely install a sub panel. I used a 6-3 wire for my panel because of the information from you. I was sure wanting to use the 8-3 just for the cost differance. The safety of my kids dont have a price so 100 bucks more for the wire was a no brainer. Thanks again for the Profesional help.

  77. I know what you mean all to well. Thank you very much.


  79. Dear Mr/Mrs
    Thanks for your website .I need electrical code for preparation myself in 309A exam as far as I got my temporary licence in electrician field.
