@@GH-oi2jf Sharing neutral across receptacles, outlets and switches on the same circuit is fine but should not be shared across circuits. It become a safety issue when isolating circuits for repair
Thank you so much for your videos! They help a great deal. Your explanations and animations are perfect, they’re so easy to follow. U have my subscription now!
Hello, thank you for very well-explained videos. I have a question, when wiring the switch, why don't you use a hot wire (black colored wire) instead of using a white wire and mark it with black tape?
I'm not an electrician, but I believe it's because you aren't using two separate pieces of wire to connect the switch, you're using one piece of normal double core insulated wire. However in this case both wires will be hot so the white wire has to be marked accordingly.
Seems like on every power cord plug one side is wider than the other and one hole on the receptacle is wider than the other yet it works whichever way way you plug it in. What is the reason for one side being wider>?
Loved this video. But I have some fundamental questions, please if somebody could help in reply! Tks, - What is the significance of hot, neutral and ground wires? (What do they represent? Positive or Negative flows, or something else?!) - Why does electricity from the "hot" wire want to reach the neutral wire??! - Why do some sockets ("receptacles") have only two slots, or sometimes three, for a two-pin or three-pin plug?
i never understood neutral terminal, since its AC as opposed to DC, the current alternates and there is not official ground.... arent both terminals technically hot because it is AC? i never understood this
just so you know it is required in code for there to be a neutral wire accessible in each switch location, so for switched receptacles you need to run a 3 wire and use the red wire in place of the reidentified white, otherwise great video just make sure to follow the code so people don't get it wrong IRL
Good point although that's is only new installs, there's still millions of these circuits installed as per the video. We'll add a note when we cover the circuits in detail thanks
Please answer why the receptacles have identifiers and how that affects newer equipment and how to test an outlet to know if it's wired properly also how to reduce noise for hifi equipment. Thanks
As far as testing an outlet goes, there is a small device that you can buy at most hardware stores. You plug it into an outlet and it will indicate, with a pattern of three light indicators, whether the outlet is installed correctly or why it isn't installed correctly. Its simple, but very useful.
Please make a video about contactors & relays :) P.S It will be my dream if you go deeper inside the parts of chiller control panel hehe I'm a chiller tech btw. I watched 95% of all your chiller related vids :D
Thank you for your explaination. However, i have one concern: in your video, you said that with AC current, the direction of current will change back and forward that means current will go from hot to neutral and from neutral to hot but potential of neutral allways smaller than hot. So how can current run from neutral to hot? Thank you.
Alternating current changes polarity, usually 60 or 50 times a second. In one instance, the "hot" wire is (+) and the "neutral" wire is (-). 1/60th of a second later, the "hot" wire is now (-) and the "neutral" wire is (+). Imagine taking a battery and flipping it around 60 times a second. It's kinda like that. It's also why polarity is not a "thing" in AC circuits... it's never constant!
Ah yes. The switch outlet use to be very popular during the 70's 80's (correct me if I'm wrong) because ceiling lights were not desired, however, it was lamps that were widely sought after.
I am very interested what happens when there is nothing plugged in. The electricity is 'pushed' through hot wire, so what happens at the end of hot wire? Since it's metal are there like really many electrons pushed besides each other, 'waiting' for electric chain to be completed? Why doesn't hot wire become hot if it's AC?
I understand the principle of Hot vs Neutral in AC, but isn't each leg "pushing" just as often as it is "pulling", ie Neutral acts as Hot half the time and vice versa? Can someone clarify for me?
Can you tell me how the receptacles work where there's 2 separate switches that can turn on or off a light? .. I mean, in our house there is a small room between two big room. Each room have a on/off switch that can turn on/off the light in the middle small room. I keep wondering how was it set?
Is there a convention to how the North American household A.C. receptacle is oriented? Should the receptacle look like a "pumpkin face" as installed or an upside down "pumpkin face" (with the individual ground receptacle on top)? In my doctor's office at the hospital, every A.C. receptacle is mounted in the face plate with the ground on top/upside down "pumpkin face". Also, the ground is marked with a green triangle. At the start of your video the receptacle is also shown like I have seen at the hospital. What is the convention and/or code standards?
There is no code requirement for orientation. The green triangle means that this receptacle has a dedicated ground wire running back to the panel separate from the conduit or metal jacketing of the cable. It is considered safer install a receptacle with the ground on top so if anything slides down the wall knocking the receptacle loose, the ground would be the most exposed terminal. That being said, it's a very rare circumstance this should happen and lead to accident or injury so most of the time it's done the other way out of personal preference.
@@shilohcampbell5810 Okay, thanks. That's some good background, and now it makes sense to me. I still prefer the upright "pumpkin face" even though it's (very) marginally more dangerous. Upside down from this, and it simply looks weird to me. I'm always a little irked by this when seeing that doctor at his hospital office.

In part, it would have been transformed down to low voltage. If you were to recieve a shock, it would only be a very mild tickle. I don't completely know the engineering, but there are probably other perameters in place to protect from shock as well.
My little brother stuck a bobby pin into the receptacle I saw him jolt into the air so fast he was here one minute and second he had flown across the room. He was okay.
Am i the only one who want to have a switch control both outlets top and bottom how can this be done anybody have a clue trying to qire my garage up right now been looking for a video on it for over 3 days
Hi I'm from India actually I keep watching Ur all video's if you don't mine can you please upload over head crane operations, list of body parts, resistance bank, and usages of types of motor's and operations please please
i still dont understand how the ground wire helps, how does it protect me...how does the current decide to go through the ground wire instead of me and why not both me and the ground wire? why does the current increase dramatically, what causes the rise?
There is absolutely no reason to run white wire to switch and use it as jumper for hot wire 4:07. This is dangerous practice, you can use red colored wire to complete that circuit. Most people assume white wire is neutral wire and is not hot, therefore it could be touched and could be "safely" worked with. White wire should only be used as neutral wire always!!! 4:39 in that part you are connecting another circuit but using only one neutral, it is also a bad advice and is NEC violation. As per 2017 NEC 200.4.A . "Installation: Neutrals may not be used for more than one branch circuit, for more than one multiwire branch circuit or for more than one set of ungrounded feeder conductors unless specifically permitted elsewhere in this code."
It isn’t ABSOLUTELY DANGEROUS as you say you just can’t do it because code requires a neutral feed in a switch box because the new smart switches need a neutral, you can also use the white wire if you tape it black but you need a feed neutral in the box so you would just use 14/3 instead of running another 14/2
Multiwire branch circuits are 2 or 3 hots that share a neutral. This practice is perfectly acceptable in the code. Also white wires may be identified as hots when in a prefab cable such as romex or MC. You must be an engineer and not an electrician, or you would know these things and use these practices on a daily basis.
@@shilohcampbell5810 You can wire one neutral to multiple circuits hots, but you must have means to disconnect all hots simultaneously, meaning single multi pole breaker needs to be in place. I never said using white wire for jumping hot wire is illegal, it's just very poor practice.
When you buy a roll of cable (IE... Romex) it usually only comes with black, white and ground. Most common. There are cables with more wires, but code allows you to identify white wire as hot so you don't have to go buy another roll of wire for just for one operation.
It's for demonstration, bud. I also don't see any wire jacketing, nail plates, wire staples, or plate covers, because they aren't the main focus of the video.
