Great video would have touched on the Transformer connected to main panel which has two hot bus bars which are connected to either end of secondary coil in the transformer and the neutral bar being connected to the center of secondary coil we get 120 from hot bus to neutral bar. but When we connect to two bus bars were connecting to full length of secondary coil thus 240 volts.

The black wire and red wire are actually in phase with one another. There is only one 240v coil in the pole mounted transformer that is split into two 120v sections. If you use an oscilloscope, and measure voltage from neutral to the black wire you will get a positive sine wave, If you measure from the neutral to the red wire you will get a negative sine wave. But if you measure from red to black you will get a 240v sine wave that is in phase. In three phase transformer, the lines are 120 degrees out of phase, but not with single phase 240v....

Residential wiring in North America is single phase, so there's no "opposite phase". The single phase alternates between opposite Lines (L1 and L2) or poles from each end of the transformer secondary windings. 240v is measured from one pole to the other, which is the top to the bottom on the sine wave you showed. If you measure side by side as shown at 2:57 you'll get 0v because it's the same point. The line in the center is 0v everything above is + and everything below is -. Measuring from the 0v center line to the peak point in either direction will be 120v RMS. The electrical panel has 2 power busses, L1 and L2 and will measure 240v from one to the other. When measuring from either one to the neutral or neutral/ground bus you get 120v.
@GH-oi2jf10 ай бұрын
It is just a way of looking at it. The hot lines are derived from a single phase input to the transformer, but they are 180° out of phase, as he stated. Whether coming from a 2-phase generator with two coils, or synthesized using a split-phase transformer, they are equivalent. It is pedantry to argue about what to call it.

Yeah, expect the OP here is spot on correct, unlike the video creator. I know enough to know everyone claiming this video creator is the best explainer on the Internet ever, doesn't know the difference btwn information, and correctly explaining a concept, like the OP did here. We use single phase in America 120/240. So to say things are "out of phase" is quite inaccurate and not well articulated when better words exist to explain fairly simple concepts... I kinda thought this video was highly inaccurate, and just dangerous enough to trick ppl into thinking they were "learning" anything of value. Ground/Neutral concepts are hardly a place to gloss over, or misinform.
@NGinuity5 жыл бұрын
This was an excellent explanation, well done. A lot of people ask me why we call it single phase instead of two phase. It is, in fact, two phased 120 volts in the strictest sense, however, as you demonstrated, when two voltages are phased 180 degrees out from each other, we call it a single phase because of the summation. If you're talking 3 phase, for instance 208 volts, that's still 120 volts per leg but the phases are 120 degrees out from each other so the result is 120 * sqrt(3) = 208 volts total between any 2 of 3 phases. This is also why some residences have 208 volts instead of 220/240 because they are in a zone that has a 3 phase grid instead of step down transformers that split tap the single incoming phase. They just pull 2 of the 3 phases to the panel.

Please review Charles Staton, referring to the line voltage not being 180 deg out of phase as this would cancel out the line voltage to zero volts. There actually is 240volts between the two hot line wires, they are not two wires with 120VAC in each. The transformer at the pole is center tapped which takes voltage from half the winding to give 120 volts. Charles goes in to great detail to prove this beyond a shadow of a doubt. I am not trying to make anyone upset or have a huge debate over this, though I am concerned that believing the phase is 180 deg out has been passed down for so long (myself included) that it is just taken as the truth. How can you have two phases on a single phase? You can't, you have a phase from 240 volts AC and the center tap or split phase reading half the voltage at 120VAC but it is from the same phase. He explains why many believe they are out of phase and proves why they are not! It would be easy to just ignore what I have just typed but living in ignorance of the truth is no excuse. Watch his video and decide for yourself. Here is his youtube link that shows how and why. kzfaq.info/get/bejne/q7h7lbtomdKml4k.html

This is incorrect; the 240V is between the Red and the Black but below the Red (the dotted lines) not next to it. You measure voltage from top to bottom not left to right. This is AC (Alternating Current); meaning that current moves back and forth between the two leads unlike DC (ex. batteries) which flows in one direction from positive to negative (mathematically). You don't use a neutral for US 240v because the power is between the Red and Black (two 120V "wires" 180 degrees out of phase from each other, meaning that when one is +120VAC the other is exactly 120VAC away from the other at the exact same time equalling +240VAC). You get 120VAC with the Black and White because the white is at the center of the signal (your lines going horizontally on the drawing) Basically cutting your signal in half. The highest the voltage will go for the black wire is 120VAC with respect to the white wire; whether it's positive or negative. The color of the wires are just industry standard indentifiers. You should never use a white wire as a "hot" lead as it could shock someone thinking that it's a neutral: If you must, wrap the first 3 inches of the white wire with black electrical tape from the connection point. US appliances using 240VAC that also use 120VAC must use the 4 wires. The white wire must be tied to the neutral buss at the power panel so that installers may use either the black or red in conjunction with the white to get 120V. This video should be re-uploaded with the correct explanation; this video will just confuse folks.

I'm assuming that your explanation is based on some classes you took and was shown using an Oscope. It's a shame that teachers can't teach better. The only difference in the two 120 volt sine waves and the one 240 volt sine wave is the amplitude of the voltage. There are exactly twice the number of windings at 240 volts than for 120 volts. The all three go up and down at exactly the same point in time. The Oscope causes confusion. You are saying I am wrong by now. Please explain how anything can be 180 degrees out of phase. There is one sine wave going in primary side of transformer and it can only generate sine waves at exactly the same time and flow direction. Respectfully, Kevin

@@KevinCoop1 Hello Kevin, my credentials are irrelevant here but if it must, I have an electrical engineering background with over 10 years experience in a Fortune 500 company and over 5 years experience in a NRTL Blue Chip company. That being said, I'll try to keep this brief and simple. - In the U.S. you read 240VAC from Red to Black because your are reading the entire winding coming from the transformer feeding your site/home. The white wire comes from the center of the transformer's windings known as the center tap. When you measure between Black and White, you are reading half the transformer's windings which is 120VAC; the same goes for Red and White. - When you measure from Red to Black you are reading the voltage at the same point in time. In the video's drawing the 240VAC is the first solid hump (its peak) on the left and the first dotted hump (its peak) right below it going negative from the center line. The red is the solid and the black is the dotted. - Since both humps are opposite each other at the same point in time when measured, they are said to be 180 degrees out of phase. - There are two sine waves coming in from your primaries when you use the neutral (white wire) as reference. You get two 120VAC sources 180 degrees from each other. - The terms Primary and Secondary refer the transformer's coil winding sides. The power plant provides high voltage to your local transformer's primary side windings. Then, the transformer steps down the voltage and provides the consumer with a lower power source from its secondary windings. In AC voltage the power does not go from positive to negative like in DC voltage; it actually oscillates back and forth. - The voltages is this discussion are in Vrms but that's a separate conversation; just like the difference between 3-Phase and single phase power or 208vac vs 240vac for that matter.

At the end I was a Sr. Electrical design engineer/project manager. Ok enough patting on the back. Everything you said was perfect except for the solid and dashed lines. In 240 volts that situation can not exist. You are saying that the two add together. Not true, they would cancel each other out and be zero volts. A 240 volt sign wave is the same length wave as 120 volt wave at exact same time, but is twice as tall. It has to be!

Zone07 To make your math work, you have to subtract a negative number to get a positive number? Yet you say that 120 volts plus 120 volts gets you 240 volts? Why are you having to use the term positive in your example? AC is neither, and it is both. In Europe, 240 volts is one transformer coil of a three phase wye configuration. The system voltage is 240/416 volts 3 phase 4 wire. In US, 240 volts single phase is two coils connected in series to form one coil. It could be one coil but, we in US because if Edison (originally) to keep 120 volts because his lamps were 120 volts. Tesla had to conform. You absolutely do not need a neutral to get 240 volts, as is the case with a 2 pole breaker on a 240v delta configuration system. Now, if you were to make your statements as "Based on the results of connecting an Oscilloscope to the system using neutral as a reference point". Then you would be correct. The test condition is the cause of your phase shift, not the transformer. I'm pretty sure you can not come up with an explanation on why there is a phase shift mechanically. Another thing that is very hard to explain is, (In a single phase 120/240 volt system, if a multi wire branch circuit has 1200 watts of load on both 120 volt hots with a common neutral, why is neutral current 0 amperes?). I hope I am not upsetting you! Respectfully, Kevin

i'm building a small heated paint storage room in an unheated garage. Think of a space 4x8 x 9' tall with some shelves, and a door, insulated walls. I want to install a heater. Oil Filled electric space heaters run at 120 volts, consume up to 1500 watts, and put off a set amount of BTU's. There are also 4 foot electric base board heaters, that lack the thermal mass of the oil filled electric radiator style that come in 120 and 240 volts. I found your video as I searched for information on "higher voltages, consume lower amps, and are cheaper to run." But with electric heat, I got the impression that a watt of energy in, regardless of whether its 1 leg at 120 or 2 leg at 240, will produce the same BTU's. And instead of drawing 15 amps on one leg, I'd just be drawing 7.5 amps on two legs, and thus wind up with the same bill from the electric company at the end of the month, and I have to give up the thermal mass of the oil filled radiator if I go to 240. BUT, i have the sense i'm missing something. Can you go more into depth on how this works with AC voltage, and amperage, and how that relates to creating BTU's with electric heat, and the Kilowatt Hour Draw and expense? I love the geeky math stuff. Thanks!!
@GH-oi2jf10 ай бұрын
Yes, your electric consumption is based on the energy. If the power (volts times amps) is the same, the energy over equal time is the same. You don’t save money with lower amperage at higher voltage when the product is the same. Losses in the wiring might be greater at higher amperage, however. Lower amps can be safer. Higher current will produce more heat in the wire. Running a 120V heater at the maximum can produce excessive heat in the wiring. I have a four foot portable heater and I noticed the plug had become scorched from heat. I never run it on the high setting anymore. It would be better to have a 240V heater using the same gauge wiring to avoid overheating the wiring. By the way, my portable baseboard heater is fluid-filled, so there is some thermal mass.

I have a 240 3 wire dryer, it stopped working so I thought the dryer went out, replaced the dryer and when the installers connected the 3 wire new dryer, they said the receptacle might be damaged. What they didn't realize is that when they plugged it in, it was sending power through the frame of the dryer, and I didn't notice this until I got shocked when I was leaning on the dryer and then touched the metal doors in the laundry room. The dryer itself was wired correctly, so I tested the connection with a voltmeter and saw 120v on the neutral, 120v on one of the legs, and about 50 volts on one of the legs when I used my multimeter on the dryer plug connection to the dryer itself. So I replaced the 3 wire receptacle (2 8 AWG AL, 1 8 AWG BARE copper Ground) using antiox for the AL connections. Turn on the power and I am getting 240 from both legs, but when testing each leg on the ground I am getting 72 volts on one side and 68 volts on the other. When I plugged into 3 wire dryer, it instantly energized the frame AGAIN, making it possible to get shocked. How in the heck is power making its way to the frame of the dryer and why is my legs reading lower voltage, but running at 240 when I test both legs? Some people referred to this as "ghost voltage" and they said that there may be a problem with my ground wire. (which the receptacle manufacterer refers it to a neutral on the receptacle itself.) Is it a ground? Is it a neutral? Why did they use bare wire, just because it's ground? When I plug in the dryer it's also sending power directly into the ground. Is it supposed to be a ground? I checked the circuit breaker box and couldnt locate anything. I am so confused.
@dougbrowning826 ай бұрын
If you have a 3 wire dryer (NEMA 10-30), there is no ground. Just L1, L2, and neutral. The case of the dryer is connected to neutral, which is why you have that "ghost voltage". This kind of setup has been obsolete for years for this reason. The modern way is to have a 4 wire cord and plug (NEMA 14-30) for the dryer, with L1, L2, neutral, and ground, that provides a separate ground path for the case. Also, the fact that you have that voltage on the neutral, and extremely low, unbalanced voltages from the lines to ground (should be 120V each side) means you have other faults in your electrical system that need attention.
@panemon1876 ай бұрын
@@dougbrowning82 I was recently able to find out why I was getting the ghost voltage, it turns out that after my new Pex installation, the ground/neutral lost continuity and I was able to fix it by bonding it to the copper pipe coming in before the Pex and it's been working fine. I was unable to see the bonding clamp on the pipe when I went to the new Pex system (which I had prefabricated.) Strange how the frame was being energized due to no ground, but the phases canceled each other out, but probably somehow used the frame as a path to ground. Both legs are showing 120v now, dryer running perfectly. The receptacle was in terrible condition and whoever installed it back in 1972 used no antiox at all, so I had to cut back some fresh conductor that wasn't oxidized and rebuilt that 10-30 Planning on upgrading to 10/3 or 8/3 4 prong 14-30. Silly that they used the plumbing to ground the dryer.

European and other countries systems are one phase to neutral from 220 to 240 volts fed off a three phase system.

Great video. My welder has a 110v 220v 3 pronged cord. My generator has a L14 20p plug in. Can't seem to find an adapter so im using a L14 30p i got from lowes and wired it to the end of an adapter the welder came with that steps down to 3 pronged 110v regular home outlet plug. My question is should i just cut the end of the welder 3prong 220 and wire my L14 how you've explained b hot and w hot g to ground with neutral open. Or use the adapter to splice the L14 onto? Also my generator is a floating neutral. Will that affect anything?

To me neutral is not really the return , it is the area of conducting material such as a copper bar where the current can reside in a neutral zone to make a device function or a path for the current on the other side of a device!

I'm confused. You mentioned that the 240v legs are 180 out of phase, I thought they were 120 out of phase. I'm also confused about terminology. I'm looking at buying a new air compressor, it has a 220v Single Phase motor but the 220v outlet has 2 phase (L1 & L2). I'm totally confused. Thanks in advance.
@timgleason25273 жыл бұрын
I can at least help you with the first part- by “180 degrees out of phase”, that means that the sine waves are mirror images of each other. To understand where the number 180 comes from, you’d have to graph a sine wave. The function repeats every 360 degrees. The amplitude of those waves is 120v. So one is, essentially, 120V when the other is -120V, so the difference is 240V.
@tedlahm57402 жыл бұрын
The confusion is BECAUSE there is only one phase in your home panel, ALTHOUGH it is split in the middle. The 240 volt outlet that you have is the OPPOSITE end of this single phase of current. Only large power customers have all THREE of the phases that the power company uses for distribution. You the household only receive one of the three. Many people WRONGLY call this one phase as two phases. I understand because it is SPLIT inside the transformer into 2 120 circuits. Yes two (2) 120 circuits BUT the combined (240 volts) is only one phase.

Would this work if plugged into 2 separate 12v dc to 120v ac power inverters. 12v solar battery bank to 2 separate 120v power inverter, going into a Panel. 120v on each terminal. Neutral bar tied to ground in panel? Ground tied to copper rod going into earth. I know the panel could provide 120v to single breakers, but could it handle a double pole breaker at 240? Assuming I had a large enough battery bank and power inverters size to handle the load. The two 120v power inverter running of same battery bank.

Some systems use 3 phase power due to more economical operation, but these may be only industrial. With 3 phase power, of which only 2 lines (phases) power the electrical system, the 3 phase (lines) divide the 360 degree sine wave by 3, so 360/3 is 120 degree. In 3 phase power each line is 120 degree with respect to the other 2 and not 180 degree like what you have shown for residential. Residential power uses a single phase then steps it down with a split phase transformer to give 2 phases at 180 degree. In the 3 phase type, you get to lower voltages like 120 using a single phase, and 208v using only 2 of 3 phases. The voltage is ac, but the reading is based on RMS (Root mean square) which is a mathematical calculation for a DC equivalent. For a single phase, peak to peak is 340 volts, then dividing it by (2 X square root of 2), which is 2 X 1.414 or 2.828, you get 120 volts RMS. 208v comes from adding 2 lines with a 120 degree phase relationship, but requires a more complex calculation than addition alone. You then must calculate the sin of the angle (120 degree) between them to get 294.4v P (588.8 PtP), then calculate the RMS value to get 208 volts. 340 + 340 = 680v (PtP) 680v X sin(120)= 588.8v PtP 588.8v / (2 X sqrt(2)) = 208v RMS.

Can someone explain why US & Canada only uses 2 phases, in Europe we uses all 3 phases, and thanks to that we can use loads that is designed to evenly spread the load equally on all 3 phases, like motors and heaters and that results in lower current on each phase.
@cslloyd13 жыл бұрын
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.

Great video even for someone like myself that is entirely electric illiterate. I found your video extremely educational/informational and if I understood it correctly, I can save a few dollars in wiring by using a 6/3 UF wire. Here is my issue... I want to run electricity from the main panel in my garage to an outdoor shed which sits about 100ft from the main box. My intent is to get a couple of outlets at 120V. One outlet for my electric lawnmower that has to remain plugged, and possibly two to four outlets for woodworking tools or any other electric tool need at 120V. Being proactive, I also want to have a dedicated 220V outlet in the event that in the future I decide to add a mini-split A/C unit, which to my understanding is substantially more energy efficient at 220V vs a 120V unit. Someone with a lot of experience as an electrician had mentioned to me that it can be done with the 6/3 wire, however, that individual is up in age and is no longer an active electrician. In speaking to the individual that is looking to land the project, he tells me that he cannot see how it could be done with a single 6/3 wire. Instead, he want to use two different wires, one for the 220V plug and the other for the regular 120V outlets. I would like to get your input as running one wire (6/3) can save me a few dollars in buying another wire per foot. If that is the case, that I can get both currents with a single 6/3 wire, I will also provide him your video so that he has a better understanding how this can be accomplished. Thanks again for this video and for your willingness to provide me a little clarification.

How much current do you need? 100 feet of #6 AWG copper is good for around 36 Amps. 6/3 is a cable, not a wire. It has 3 insulated current carrying wires (black, red, and white) plus a ground wire (green, green/yellow, or bare).

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.

@94SexyStang8 ай бұрын
Neutral is technically there because 120v is Out of phase.......with 240, there's no "out" of phase operation, the "peaks" of both 120's balance each other, so it's Like having Neutral.(look at his chart he made).....neutral is a return, But also because it's out of phase as well......remember it's ALTERNATING current, particles are running back and forth threw the wiring, not DC that goes in One direction. It doesn't matter if you blast 2 - 120v wires at each other, because it's Alternating back and forth! And the peaks Cross each other, like I said, gotta look at the chart he made to understand it more.

Apparently this welder expects me to have 240 power that incorporates a white neutral wire. What do I do?
