At 11:11 you mentioned using a double pole breaker for two 120v circuits. Sometimes it's advantageous to have a split duplex receptacle in which each socket is on a separate circuit. You'd want them to turn off together, so the outlet is completely off if someone wants to change something or whatever and to prevent a situation where half the outlet is still live. You could use two single pole breakers as you stated, but the levers must be tied together, it's required by code, whether it's a 240v circuit or two 120v circuits. Overall, I think you did a good job on this video, George.
I was about to convert a stove plug 240V into a 120V for my welder but now I am wondering if I can use that stove wire from the original fuse box as a feeder wire to a subpanel? This way I could run my welder and my RV off of the 50 Amp subpanel. Am I correct in thinking this? I would be working with an electrician in the final stages and could possible up it to 100Amps but need to rearrange my orginal fuse box a bit.
I have a storage building/workshop I want to run electric to. I want a 240v 50 amp plug for a welder and 120v for lights and other tools. I have 4 wire 10 gauge ran underground from my main breaker box on the back of the house to the building but nothing is connected yet. I also want to use the 50 amp 240v to backfeed into the house with a generator in case of a power failure. Would I have to have a small breaker box in the building for the 120v on it's own 20 amp breaker? Would having a 50 amp breaker in the main box and a 50 amp main breaker in the building box cause a problem? I was told that it would but I don't understand why.
Since Im not a plumber or electrician I hate doing plumbing, it takes me 3 hours and 82 times to thread and rethread a watertight seal between two pipes. I have much better luck with what little electrical work Ive done, but I can completely fry myself. Im overly paranoid so If I have to replace a breaker or wall outlet, I shut the whole damn house off at the master breaker. :D
So my line coming into my light pole is 2 blacks and a green. Then I have 3 lines that go up to 3 spot lights. The lines that go up are a black, a green, and a white. To my understanding is that 1 of my black hot should connect to the 3 blacks going to the lights, the other black should connect to the 3 whites going to the lights, then the green coming in connects to the 3 greens going up. My problem is that all I get is my lights are humming but are not lighting up. Plus when I touch the green coming in to the 3 greens going up I get a spark.. I can't figure out what's wrong. Also all of my parking lot poles which have 3 lights on each pole and I have 3 poles are connected to a double pole 30 amp breaker and it's seeming very weak. Any help will be greatly appreciated
I’m doing the same thing I’m using a Homeline breaker box as a Sub panel a 100A box “ & thanks for the heads up on the separate ground ing bar for a sub panel !
You're a really good teacher brother and you got a good spirit. Somebody messed with my pool timer box and I don't think they put it back right you saw a picture of you probably tell me what's going on in 10 seconds but I might have it figured out before you even respond to me you're helping me to understand. But I think somebody actually brought power into this box with two extra wires they didn't use. But I was searching for someone to show me the way 220 versus 120 works and you're doing a good job of it be blessed
I'm a little confused. In dc circuits if you place to power sources in series the voltage is additive such that if you have two 12volt systems in series they together become a 24 volt system. Yet you say that in ac circuits this additive effect is dependent on the phase relationship of the circuits being out of phase with each other thus creating a mean voltage or 220 -240 from 110. But. The supply from the power company eventually goes back to an generator / alternator that is producing what one would think is synchronized power. The end voltage i can get to. It is how we are getting there That seems a bit fuzzy. Thing is, as you've stated time and again. If you don't respect it. It can and will kill you. So I wish to understand a bit better.
Excelent video, you're a very good teacher Sir! By the way I have been a person that has delved into the art & science of brewing beer. Thanks for your video, Rocky
Thank you so much you're a great teacher reminds me of my Grandpa except he had me holding the ignition coil of a generator to check to see if it's parking preach the word of God the way you teach electricity
One correction, tripped and off are not the same. Yes, neither will have power energized but the tripped position on the breaker is basically in the middle of the breaker, between on and off. You can only get to tripped by overloading the circuit or shorting the circuit.
LOL, agreed.. I've been watching a bunch of your videos and just want to say THANKS for the time you spend making them, I've learned a lot. I would like to see you talk more about how to use thumpers and the uses of tails, or as Popcorn would say, "back'ns".
Interesting to see the different system used by America compared to how we do it here in the United Kingdom. We only have single phase 240v for domestic wiring (and 3 phase 440/415v for commercial set ups) nice one George
Very true but the basics are still the same. Your two wire is 240 (one hot one neutral) and your 440 is (two hots a neutral and a ground). Exactly the same only different LOL. Oh! you are also on 50 Hz whereas we are 60Hz. Anyway, electricity doesn't care what culture uses it, it acts the same everywhere. Kind of wish politicians did the same thing. George

Really appreciate your videos!!
Your a great teacher !! Explain everything every time perfectly!
Thank you sir

I have a red and black from my power panel and I have a black and white in my 220 motor does black always go to black? Thank you Mark
I am very glad to find and learn about 240V from your video. Thank you for taking the time to teach us
Wow,
I just learned a lot.
Thank you!
Can I use an ac quick disconnect as a replacement for a gfi to run 2 pig tails to it to get 240 to my 3 prong out let
Simplistic explanation. Good job!
Thanks .. u answered a question I had about 240v.. great video
I’m doing the same thing I’m using a Homeline breaker box as a Sub panel a 100A box “ & thanks for the heads up on the separate ground ing bar for a sub panel !
Very informative and easy to understand. Thanks!
I got 280 hot only no neutral coming in how I make 110 out of it
Stop the sale of video cameras,no it's a mental health issue.Out of phase ,understatement!
Your awesome thanks, that was very clear.
George you are tremendous teacher. I needed this video to understand my box better.
Probably one of the easiest explanations on 120/240v systems I’ve ever seen
Thank you so much
🇹🇹

Fuck ya bud your a life saver

My brain right now 🤯
Thanks for physically showing it. It helps a lot more than just PowerPoints.
Thank you so much you're a great teacher reminds me of my Grandpa except he had me holding the ignition coil of a generator to check to see if it's parking preach the word of God the way you teach electricity
Amazing
I am lucky to find your video. You did an excellent job to explain well!
Thanks. Typically an air handler at a residence is only 120, but the condenser outside is 240.
Love it
All these years and I finally understand this.😀

Shut up
So... drinking and doing this is bad?
Probably

I'll see where I can fit that in
You are the man!
