Remember guys, what you see shown in this video is ONLY for 1 or 2 receptacles that you'd like to convert on a DEDICATED Branch Circuit. You MUST confirm that there's nothing else on the branch circuit that you intend on modifying. The branch circuit used in this video for the demonstration was for a washing machine. You can also convert a 240V wall A/C receptacle in a room to 120V if the home no longer uses wall A/C units because the home was modernized with central air. Thanks for watching!

Only if it's split rail feed with a neutral. Many 240V feeds are two wire.
Is there any reason that you have to make it a single receptacle, if you want to plug in multiple 240 volt capable items?
Is it possible to split the black wire instead of converting the neutral to a hot line? In my case I have limited brakers and lights are also hooked up to the same braker.
@@draketracy6969 that would not double the voltage. You're just making a pigtail which does nothing.
@@dlloyd6300 lol thanks I replied to my other comment ..
Another terrific "how to" video that's taught me something I need to know! Thank you!!
Thanks for watching! I'm looking forward to tomorrow's video!
Hi PF, you should test accuracy of electricians torque drivers, their cost of periodic calibration, etc. Both on incoming performance, (when sent in for cal, is it out of spec? Then find the last year's homes were loose?) and after re-calibration. Myself, I would trust a decades experienced electrician over a so-called torque wrench.
But are you going to test that? 👍🏼
didnt expect to see project farm here. thats awesome lol
@@mr.e8543 why?
I needed to change a 240v baseboard heater line into a 120v receptacle and this is the video I needed! Thanks for the know how! Works great and now I have an extra circuit to play with.
Great to hear!
Wow the way you explained everything so well that anyone can understand it. I get nervous when seeing people mess with the circuit breaker without turning it off. You obviously know what you are doing but mistakes always happen. People ALWAYS turn off your circuit breaker when working on it.
I usually hate instructional videos because they're always way too long but only have about 2 mins of real talk. Sure this video was slow but it broke everything down perfectly for a beginner. Thank you
Glad you liked the video!
Thankyou for your video. I might as well have electro-phobia but I've seen others make instructional videos describing the same. I'm also in a bind and just cant get 220 wired in from an "expert" and also cant pay "expert" prices for a lil ole outlet. Its cool, I will do this and am responsible enough to cross compare your information with a massive amount of information I gather from other sources. As a responsible human I can arrive at a consensus and choose how to proceed. Thankyou for your contribution to the DIY space. People Like me are very thankful and will not BLAME YOU if we screw this up! You rock!
Man this video is awesome, i was working as an electrician's helper for awhile not too long ago, but the boss wasn't really keen on teaching me things like this. However, i watched him and asked questions, and learned some. I'll also admit, i'm not as quick as a learner as I used to be. Yet, from all that and watching this. it's safe to say I understand the basics. I'd be the perfect entry level electrician's helper for sure.

Thanks for being so concise and thorough. You're a good instructor.
Good explanation. One crucial point is that it's mentioned to turn a breaker on at one point. The tutorial then continues as if the breaker is turned back off, however, this is never mentioned. Timestamp at 7:10. If a beginner is watching this, they may experience a shock because of this. Other than that, it was complete and explained well.
This is soooo old but soooo gooood! The knowing the possible is good enough, the way the information was related makes it stick in your head. Thank you....
I really like the detail in your presentation. Thanks for the great presentation. A minor safety tip is hold the receptacle so that if your screw driver slips it won't skew your holding hand.
Glad you enjoyed the video Calvin!

Excellent video. All I'm saying is this. Experience or not, keep poking around in a hot electrical panel with anything, especially a metal screwdriver and your gonna get bit! I know it sounds backwards, but experience at this point is your enemy. No doubt you already know all this. Be safe..
my thoughts exactly, as i was waiting to see some arc blast.
At least use insulated screwdrivers.
Rubber!!?
Rubber saves lives🤣🤣

Great to hear!
Love the extra suspense element of having it live and pointing with the metal screw driver.
LOL
Yep typical electrician.
I enjoyed watching him work on a live panel with a wristwatch with a metal band. So exciting!
@@electronicsNmore you laugh at Clive and jumped into the throat of a guy you claimed was a brit. But as a former licensed journeyman electrician and OSHA 500 outreach trainer who teaches OSHA 10 and 30 hour classes, the safety things you laugh off now will kill you later. I’ve been to enough electrician’s funerals who were invincible like you.
Perfect timing! I found an old 240v Craftsman air compressor in the trash and lugged it home. I'm curious to see how it works! Just need to swap out one of my 120v outlets in the shop to 240v. This video was very helpful! Thank you!
You need to make sure the receptacle is on a dedicated branch circuit before converting, otherwise you'll end with 240v at a 120v receptacle.
@@electronicsNmore I could see that causing a problem for sure! Will definitely make sure there is nothing else on the circuit! Love your videos! Thanks again!
Excellent presentation. Concise and just enough views of the actual work being done. You got right to the point without a lot of unneeded chatter. Have seen a number of these and yours is the best.

Just an FYI:
It's perfectly acceptable to have a 15 amp outlet on a 20 amp circuit so long as there are at least two outlets on the circuit. A single duplex receptacle qualifies as two outlets.
The reason why it's safe and code compliant is that 15 amp receptacles are built to the same standards 20 amp receptacles are. They are perfectly capable of passing along 20 amps. If you take a 15 amp and 20 amp receptacle apart, you'll find they're almost entirely identical except for the extra sideways slot for 20 amp plugs.
Tl;dr: so long as you don't need to use any devices with a 20 amp plug, 15 amp receptacles are just fine on a 20 amp circuit.
@@Billy.80 Whatever. OP’s statement was overly broad.
I wouldn’t assume existing outlets in an older home are able to handle 20A. Heck, some aren’t even polarized or grounded. I certainly wouldn’t encourage people to put 20A through them and I’m sure our man making the video doesn’t want the legal liability either.
Old outlets/wiring is exactly why our Chevy Volt defaults to 8A on 120v and requires you to override for 12A. It specifies a Level 2 charger (220-240v) and a 30A receptacle for a maximum of 16 amps.
Never seen any electrical device or appliance with a 120V 20A male plug, in any residential, commercial, or industrial setting.
@@WoodgemanX I've seen one old window AC that used a 20 amp plug. But that's incredibly rare, because usually anything too large for a 15 amp circuit switches to requiring 240 volts.
@@emmettturner9452 you may have a point that some old outlets really aren't capable of passing through 20 amps, I dunno. But anything not extremely old certainly can, and if you have outlets so old you're not comfortable that they can pass 20 amps, I'd probably consider replacing them.
@@elijahwatson8119 I just went back to the tornado-damaged home we used to live in and found that the landlord’s contractors did not repair the outlet my brother left hanging out of the garage wall to draw their attention to it. It was melted by that same Chevy Volt charger I mentioned before that draws a maximum of 12A. Many outlets cannot sustain the amperage they are rated for. That is the exact reason you have to override the default of 8A every time you want to charge at 12A. The home was about 15 years old. The place we are staying now is also tornado damaged. I believe it was built in the ‘50s and most of the outlets are like nothing I’ve ever seen. They almost look like those foreign outlets that can take blades or round prongs but they are actually two T-shaped contacts with no ground. The place has no heat so we have to run space heaters but there’s no way would I run 20A through these.
I just had to install a 240v garage heater in my rented workshop so I could sleep there. 240v equipment is against the least but they already had a NEMA 5-20 connected to 240v. I didn’t find out until I plugged in my shop lights and it fried them. Now I play dumb just so I can get the car charged at Level 2 (no other place to charge it) and I get to run the heater. I still don’t trust the old outlet so I swapped it with a NEMA 6-20 and made a NEMA 14-30 pigtail for my heater.
stellar explanation and demonstration. I finally get it.
Very clearly slowly safely demonstrated. 👍
Thanks for watching James!
One of the best elec videos that ive seen.
15 A receptacles are allowed to be on 20 A circuits for two reasons: code and specs. Every good quality 15 A receptacle is specified to handle 20 A pass through on the terminals. Then again, it’s always better to pigtail instead of use both terminals to avoid dealing with pass through current in every receptacle.
Great and informative video. Thank you!

Just a technical question. Do you happen to know where in the NEC it says you can mark neutral(white) wires as hot (or another color)?
As far as i know NEC says you can only do this if the wire is 6AWG or bigger. So as far as I'm aware, this video is not code compliant
WOW this is such a great and informative video. Thanks!!
Glad you enjoyed it Richard! Be sure to check out my wide range of videos as well. Thanks

The receptacle only has to match the circuit for amperage rating if it’s a single receptacles on the circuit. Code allows for multiple 15A receptacles on a 20A circuit.
3:50 perfect ElectroBoom opportunity 😁
Good video!
Thanks for watching! Be sure to check out my latest electrical video as well.
I liked it when you said make sure only 1 device is connected to the circuit when converting. This is always missed! Great job Thumbs up and a like from me!
Why can only one device be connected to the circuit?
Man, watching your screw driver tip hovering between the two bus bars were exciting!
LOL. It looked much closer than it was.
Also , touching a live bus is not a huge deal, as long as you don’t touch anything else, the other bus or the chassis of the box. I’ve made the mistake of moving to fast with my screwdriver in my hand and accidentally grazed both live bars, melted the tip off my screwdriver and I stunk like burnt electrical for the rest of the day. Ruined a nice Klein screwdriver
This is amazing sir. Thank you very much for this video. My only question is what if we have a plastic outlet? Where does the ground wire go in that case as we don't have a small enclosure to connect to?
You mean plastic electrical box? If so, then you should have a bare copper wire or green colored wire that you connect to the receptacle's ground screw.
Converted my kitchen 20A duplex’s to a single 220V and am running a 2.4kW toaster and a 3kW kettle - breakfast is ready much much faster now!
@LabRat Knatz brought them from the UK. Installed some Leviton BSRDP-W outlets - awesome setup.

As per code you can use either a 15 or 20 amp outlet on a 20 amp circuit.
Only if it’s duplex. If dedicated simplex, it must be 20 amp on 20 amp branch circuit.
11:07 Ha! Neutral bus seldom has a dangerous potential on it, except in rare conditions where the triplex meets the tails, and the ground connection is faulty. Note that it is _never_ save to touch a neutral on the inside wiring, because the return path to the bus is unreliable. Many will be shocked to find this out the hard way.
Laughed when he did that. I'm inside a box like that, I'm wearing gloves and using insulated tools.

My apartment they replaced my 240 AC with a 120, and plugged it into a nearby regular outlet. The 240 outlet was left unused. This overloaded the outlet circuit which was constantly tripping, I replaced the 240 with a single 20A 120v outlet, and corrected the connections in the box
I don't know why but 240 volts has always been a mystery to me. It never occurred to me that you could do what you just did. Thank you for explaining it so clearly a five year old could wire it!
I suspect not shutting the panel off and using a metal fish tape in a live panel are just a few bad examples that could eliminate a few of those five year olds pretty quickly. You should get a licensed electrician if you do not have the training before you make an ash of yourself or find yourself homeless.
Not all of us are electricians; many just can’t afford to pay one!
If you find yourself saying "There's a free spot for a new breaker! Hmmm, Hi Leg? High Leg? Wonder why someone wrote that on the free spot? " then you can't afford not to hire a licensed electrician!! Bye leg!! Lol. 🤯☠️. 120 Gets your attention. 240 gets you for keeps.
Richard, Instead of listening to what most people say, think of it this way. Your panel is 240 volts hot to hot. A neutral is added half way through the transformer to get two 120 volt connections.
@@philewuppallthwagh226good observation. If you come across a panel where every third slot is unused or occupied by a two or three pole breaker, the panel is almost certainly going to be three phase, supplied by a high leg delta, at 120/240V, 208V - ground high leg (or very rarely, 240/480V, 415V - ground high leg) . An easy to make mistake with this system is connecting a single pole breaker to the high leg - required to be marked orange and land on phase B (or C, for installations prior to the 1975 NEC) and smoke up everything on that circuit, always verify with a meter, in case the prior electrician was drunk and forgot to use the correct colors. ;-)
These services would only be found in commercial or industrial settings where most of the loads are 3 phase machinery, with limited 120V loads.
I have been baffled as I think in DC and although never had an issue with 115 with the neutral, the 230 concept escapes me. AC being a different beast the box was also a place on confusion. Never thought about I guess what they call phases, and even after over decades on the planet I have wired houses and changed out breakers, switches etc I still always thought a neutral (which i equated to negative) was needed. Your video helps alot as i was just wanting to convert some water pumps to 230 and never even knew the wire colors. Will have to rewatch in order to rewire my thinking from years of working on cars, bikes and some planes.
Dude, just remember 110 plus 110 equals 220. All the second one is, is two hots instead of one. super simple. Same concept with two hots.
@@jackreacher4100 Yeah I just had to accept the fact that it just the way it is and a different animal from DC
I was thinking the same thing... wondering "sooo, how do you get the neutral?" I guess since the neutral and grounding bar are the same thing, he's using the ground wire as the path back to the panel to complete the circuit.
@@Ottero87 I don’t think the 230 needs it being alternating phase, but don’t quote me as Tesla was a genius…
Good video, I've never watched you before. I was hoping you didn't add a jumper from the same phase in the outlet box. 🤣, I 've actually run across this before.
Glad you liked the video Mike! I'm sure plenty of YT videos show that mod. LOL. Be sure to share the video link with others. Thank you

Cool tutorial :D
Glad you enjoyed the video! Thanks for watching
YOU EXPLANE CLEAR IT WAS GOOD
Great video.
Although in most cases a 240 volt receptacle will be on an individual branch circuit for one appliance such as a heavy duty air compressor in the garage, there are some situations where it is acceptable to convert a 120V circuit to 240V, with more than one receptacle, replacing all the receptacles with NEMA 6-15/6-20. You'll most often see this in grow houses where high powered grow lights are used, since this allows for twice the total wattage for a given amp draw, thereby resulting in significant savings in wiring costs. Most metal halide, high pressure sodium and LED luminaries have quad ballasts, where they can be wired for 120, 208, 240, or 277V, with some models having 5 taps, allowing for 480V as well. Many integrated LED luminaires, and commercial grade electronic fluorescent ballasts are 120 ~277V universal voltage as well.
I don't keep up with changes but the last time I looked NFPA 70 it didn't allow changing a small neutral wire to a line by coloring just the ends. That was only allowed for 4 AWG and up.
NEC 2017 and 2020 started moving into identification of conductors. They avoided it for decades.

@@electronicsNmore Sometimes web counter algorithms can be iffy. More than 20 years ago, I tried out different applets for this. Visit counts can be implemented exclusively, inclusively, and with a laundry list of options and or bugs. Back in the old days it was elementary for someone to pump his own counter with a bot externally, and the big boys like Google and Yahoo try to prevent this by implementing their own devices. But any thing can be circumvented, even with the shortage of available IPv6 addresses. There is a a lot of cheating on sites such as Flickr and Facebook... That said, the analytics don't always stack up on the view count, especially with so many public IP addresses being reissued by broadband providers who provide service for LANS, WANS, etc..

Shall we use earth leakage protection breaker.
If yes, what are the recommended specs manuf./model.
Good video, always be careful of shared neutrals especially in older houses or homes with lots of addition or in commercial environments where things are always being added, You could potentially send another leg of 120v to things you don't want to.

Great explanation, however since the circuit is ran using conduit (PVC) you must replace the white conductor with a different color. Taping the white conductor would be acceptable if the wiring system was a cable, but since this is conduit, it is against code to color identify wires that are smaller then 4AWG.
geez. Make your own video.
@@anthonyz5671 pretty simple: you can't phase tape conductors smaller then 4awg in a raceway.
I believe the NEC says the ground must be green and the neutral white if under #4. The two loads are not discussed in the NEC and can be taped or colored to identify them. We do it all the time in our jurisdiction and never fail code inspections.
Great video. Helped me win an argument 😂
Thank you very much for this explanation. My question is which wire functions as the neutral now that both wires are hot? How does the circuit complete and the electricity flow back to the panel? Thank you for your assistance.
You're welcome! The neutral is nothing more than a center tap of the Transformers winding. From either end of the winding to the center will give you 120 volts. From each end of the winding or the full winding you will get 240 volts.

I would really find interesting if you could make some testing of different type of fuses, an another testing battery connectors like Anderson connector, XT90 and so. I wanted to put an Anderson (120 or 175ah) connector to my 12v lifepo4 battery to connect to my inverter for 2000w, but i don't know if i would only create resistance.

But why did you add the green ground to the knock out connector, the conduit looks to be plastic? Wasn't it already grounded?
Now it's double grounded..... MUahahahahaha
Great Great tutorial , not sure the average person could follow or understand, a lot if information. Hopefully this will send the average person to a license elect.

13:13 what would the half inch breakers connect to? Both tabs are used up on the space saver breaker.
You can see the busbar not only has a long thin section that goes from left to right for the 1" breaker to snap onto, but also a short thin vertical section just above and below the long area. Thanks for watching
I was able to install two 240 volt 15 amp outlets for a Creda and then a Bosch set of washer and dryers by adding two extra circuit breakers. The first European machines sold in the USA were able to run on 60 hz 240 volt 15 amp flat blade plugs like you showed in your 15 amp example. Is that a NEMA 6-15 outlet? This was done back in the 1990's.
Yes, NEMA 6-15R. You can also do this if you had a 3000W kettle imported from Europe, although you'd have to use or make an adapter, or cut the plug off and wire on a 6-15P to use it in the US. Appliances with motors or transformers imported from European countries, however, can be problematic when used on 240V in America, because they were designed for 50Hz, whereas North America uses 60Hz.
Excellent!!!
one of the best explanation
Glad you think so Erwin! Be sure to look over my video playlists below for many other videos of interest to you, and most importantly take one minute to share a link to my channel with others on social networking sites. Thanks

Thanks for the video. very informative! I find difficulty with identifying the white wire. it is easy to find here because it was the only one running in that EMT. how would you identify it if it came from the same bunch as other white wires?
In that case, much more work. You'd need a wire tracing tool(signal tracer).
i have a question for you after i liked your video.. if i do what you said in the video and i have more receptacles have 120V. and i need to keep them at 120v. what i should do?
Can covert power source from power going to the o house that is one line of 220 and neural ?
Thank you may I will change 240 voltage for electrical range like this . Do I need to change the wire also? Or more big wire? Thx
