Really is the best video I’ve seen on electric. Explained things that allot of people don’t know.

I find that technically minded and technically curious people are more drawn to brewing to begin with.

He's showing how to hook proper power to running the stinger for the distilling machine

best 120 and 240 volt wiring video*

George is the man.

BTW, thank you very much for educating us on this! This makes everything about 120v/240v make sense for me now.

This sounds like my lead tech

You all probably dont give a damn but does any of you know a trick to get back into an Instagram account?? I was stupid forgot the password. I appreciate any tricks you can offer me

what? where? That's the only thing I came to learn but he just says it doesn't need neutral because it has its own. Basically: "It just works, like magic!" I presume the alternate phase allows the hots to trade as neutrals for each other but that may as well be magic as far as I can tell.

doesn’t need neutral LoL. check your breaker designs if you value your life and don’t like electrocution.

Great point!

Lmfao. That's a resi guy term. Neutral is absolutely tossed around all the time in commercial. NEGATIVE is for DC.

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.

i love the explain. i used this a lot when putting in AC units....lol kzfaq.info/get/bejne/n75jnttyppiwZIU.html

Very well said. I just learned much more about 208 than I knew before. Thanks George

This is priceless. Laughed hard and long. 220, 221 whatever it takes....

@@BarleyandHopsBrewing....the first thing i had to look at the panel box to see if their service could handle the new equipment. my helper and i would set up the home owner with that .. 220 221 whatever it takes...lol

I plan to use this line in a video soon. I just think it's the funniest thing ever for those who understand basic electricity. Can't wait to lay that one out there and see who replies.

@@koisolare Knowledge is a wonderful thing. Try this link. It should clear things up. kzfaq.info/get/bejne/pLWDjKuG3a7cd2w.html

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.

Zone07 I am currently retired. I started electrical design 1983. I worked for a top 12 in US privately held electrical contractor for the last 21 years. 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! Please see my comment and all follow up comments at 10 months ago with the author of this video. My last comment is the one I would like for you to read. Respectfully, Kevin

@@KevinCoop1 in Europe a single phase positive peak is 230Vrms but in the U.S. in order to achieve the 240Vrms, we tap into both legs of the transformer (the two hot legs on your panel). The total voltage is the difference between both peaks (120vrm-(-120vrms)=240vrms). This video I just found will provide a better visual explanation: kzfaq.info/get/bejne/q6uDZMxjz6zbenk.html This other channel provides great visual lessons as well. I recommended this channel to my kid who's going to V-Tech for EE. kzfaq.info/get/bejne/hpOHZ5Wl0JPKh5c.html

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

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.

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.

@@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.

You get 120V in the same phase at different times, but they are in opposite phase at the same time, all the time.

So could u run dryer off the 3 wire 240

Here 240V is one phase.

This is awesome The correct term is that it is a 120/240 volt single phase system. Again, single phase system.

@@KevinCoop1 Sorry in the US 2 phase is 220V In Australia, UK, etc we use 240V Single phase.

This is awesome Sorry 120/240 volts is a single phase system. Transformer is single phase in, single phase out. The only two phase systems were Tesla early poly phase system before he changed to single phase and three phase systems. Niagra falls originally were two phase. European and other countries systems are one phase to neutral from 220 to 240 volts fed off a three phase system.

😅😅😮

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.

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.

Single phase is single phase. Not two phase.

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).

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.
