The US electrical system is not 120V

3 роки томуIt's more than 120V. It's even more than the other 120V! It is the sum of the two (and sometimes a different two!) that makes us who we are. Learn about the US electrical system in this not-at-all snarky video!

One of these days I'll tidy up that wire... A minor note; the thing about 208 being 86.7% isn't right for simple resistive loads like heating elements. You'll actually only get 75% the heat on 208! Power (watts) goes up with the square of the voltage. But, if something is designed specifically for 208, you can pull up to 86.7% what you could on 240 with the same amperage.

Your neutral and ground wires are not looking to (current) code: 1. There are spots where two wires are under one screw. 2. The neutral and ground are not separated (yeah, I know, they are the same potential, but the code says they need to be separated... for reasons.). But the panel probably predates those changes. PS: Wear your electricians gloves when working on a live panel... including just poking at it with a meter.
@ChrisCaramia 3 роки тому
The two wires under one screw is a definite no-no. In my area, however, both neutral and ground must be bonded to the box. It is ridiculous, but that is what the inspector demands.

Actually in Germany we typically have 3 phase power to our home. This means you have 3 powelines, 120° appart and one ground. Depending on how you connect these between eachother or to ground you get either 380V or three times 240V. Bigger machines like washing machines, driers, ovens etc. use the 380V three phase power. Other smaller machines, connected to the normal outlets, use the 240V single phase power. Usually the fuses for the main lines are 63A for each phase. There are other breakers like 125A, but these are not so common in normal households. Hosehold machines thypically have lines with 16A breakers. Bigger industrial machines use 32A lines ore less commonly 63A.
@chris_3729 9 місяців тому
Yeah that's true for the most part but the voltages are 230V and 230VxSQR(3)=400V Fun fact the "normal" 230V plug is only rated for 10A consistently but u can still pull 16A for a short periode Greetings from an electrical engineer from Germany
@hughleyton693 8 місяців тому
In Germany, the 3-phase is 400V. . . . Which naturally gives 230V Single-phase. . . ( For Americans, Single-phase is a SINGLE live line and Neutral. ) . . Not like their 2- phase 120/240V which is TWO Live lines and Neutral.

Do you really use 3 phase power for washing machines in Germany? Most run just fine on 10A / 240V single phase. Your fuses are also pretty big at 63A. In the Netherlands we usually get 3 x 25A. More amps are possible, but at much higher monthly network charges.

When I was a kid, my little brother decided to drop a penny behind the outlet cover in his room. It was an old 120 2-prong receptacle and that penny fell in just the right way to bridge the gap, my family was all surprised when we screamed. I'm not sure why, but I was the one who ran out, through the living room and kitchen to get to the breaker box. Being 10, I just turned everything off as quickly as I could. Needless to say, my dad pulled out the remains of the penny while replacing the outlet and it proved to be a good lesson to all of us. My dad doesn't neglect electrical repairs these days. Though I don't know why he never did anything about the one power switch in a place we lived in for a year that almost always shocked us. Well, actually I do. My dad was in terrible mental health during that time, so it took a lot out of him just to provide for us. He and my mom had split because of it, which honestly just made things worse, but that's all a different story. The electrical system in the US isn't something you should play around with. Thankfully I know some electricians, so I know who to call to help me. Also, I checked my panel. 100amp @ 240v. I figured, being a manufactured, single wide home. I think I'll save up and get my electrical system reworked, though. The place is about 30 years old and I would like to make sure it's all up to code.

I went to tech school for HVAC, and I was never really taught the difference between 208/240. Even my super awesome, smart, one-of-a-kind electrical instructor never really mentioned it(I learned a lot of other really valuable stuff from him though, and particularly have a better working knowledge of how motors work than most of the HVAC techs I work with, thanks to him) I had no idea that 208v was from 120v-3 phase. In my (limited) experience I've pretty much only worked with 240v-3 phase or split-phase120/240v and only ran across 208v once or twice, and had no clue why it was different. Thank you sir, I've learned something new today! Been watching your videos for a long time.

Personally I love that we in (mainland) Europe use E/F plugs. While technically F is the Shuko-plug, you'll find that many electrical devices and powercubes and -bricks accept both E (found as (older) French, Belgian, Tunesian and somehow Slovakian outlets) and F. The diffence is in grounding:: E adds a third plug, F has the grounding on the side. Both sides, so you can put the plug in upside down or not. And two plugs is simpler to plug in than three. All in all, I love our Schuko-system. And that also means we use Type C if grounding is not needed. Handy for, well, you find these still on 'boomboxes'.Or gameconsoles. Audioequipment. And your tv.

You know this is really just a great example of engineers solving safety hazards through different methods. When analyzing hazards you got two scales, likelyhood of injury, and severity of injury. In america, we decided to tackle the severity part, dropping the voltage and making it less likely to kill you as easily. In britian they tackled the likelyhood part, designing better plugs, leakage current detectors, ect. In both places they felt that these considerations brough the hazard level down to a point that was acceptable and moved on with their lives, not thinking about it much more after that.

@lal12 2 роки тому
Not necessarily true. In Europe you have 230V on one phase yes, but pretty much any house has 3 phases coming in, so you can use 380V for higher power devices or for devices like a motor which needs it to function anyway. So using the US system is not really applicable for Europe anyway. Those 3 Phases have the same safety advantages the split phase system has. Besides I would argue that the severity of injury is not that highly reduced by 120AC, since the things that make AC dangerous are the frequency which the heart still can react to and the body having a lower impedance than ohmic resistance, which means AC can more easily pass through it than DC. So decreasing the likelyhood of injury is the only sensible way to go here.
@eleftheriaithanatos1162 2 роки тому
@@lal12 In the UK and Ireland it's not really common to have 3-phase in a household. Neither is it in Australia or NZ (230V@50Hz, just like Europe). I hear the same happens in France and the Netherlands, though I may be wrong. Also, they get far less amps, which means that even in Germany, where 3-phase supply is commonplace in households, the maximum power is lower than in America. That, of course, comes at the expense of having to spend a little more on wires, but the cost is marginal relative to the cost of a house. Having three-phase for households has many advantages though, but they are related more to the possibility of running more efficient motors (3-Phase Air Conditioners, for example, are becoming very common here in Brazil for residential use, where three-phase supply is quite common for homes, though not ubiquitous as in Germany). Now, 120VAC is unquestionably safer than 230VAC. Your resistance doesn't change when you are closer to a 230V outlet. U = RI. Hence, the current going through your body IS nearly twice, which means a much worse shock. The higher the current, the higher the risk.

The Earth connector is fully copper as that needs to be stronger as it opens the shutters in the socket but as it doesn't (mostly) carry any voltage, touching it doesn't matter.

That is just one thing about the square pin plug i wish we had, the ability to switch an outlet at the outlet itself. But i think what people forget is that the american BI plug is older. A lot of other plug standards had the ability to learn from previous plug failings. We didnt really have that chance and since compatibility is a thing we just kinda got stuck with it only modernizing little bits like polarizing the plug with the neutral being bigger and adding the circular ground pin, as an option wheras the square pin a ground lug is required to operate the safety shutters in the plug even if its just a fake pin of plastic, and really the bi pin could be made better by shoving a bit of plastic on the end of the pins and making the recepticle make contact on the tip of the pins, that way compatibility is kept for older plugs but newer plugs are safer, the fact that our pins are to close your fingers could also be negated by making the plug a bit bigger with a more pronounced shield, but like I said its a standard weve had for a while and since japan and china also use the bi pin for residential appliances its not gonna change anytime soon.

You bear analogy is way off.

At most household situations, this is reasonably accurate, in fact most household electroctrocutions deaths are caused by closing the el. circle via low resistance path through the body into a lower potential point.
@mubashirsoomro6 3 роки тому
@@bozoc2572 The point of my bear analogy wasn't to say that the current doesn't kill you ( and it certainly doesn't paint the whole picture, there are constant current and voltage sources not to mention dependent and independent ones and as you mentioned frequency and impedance ), but the point is for most household outlets we are dealing with constant voltage sources, and given the body's resistance on average, they could supply enough current to kill you. So in this instance technically both the claws and the bear are responsible for your death. As for your second point, certainly if there is a loop with low enough reistance even a 1V(DC) would kill you, but that's the caveat "low enough resitance". And I don't understand your last point; by lower potential point, do you mean a potential lower than the ground? Because, in that instance the net voltage does increase.
@giuseppebertolini6705 3 роки тому
It’s the amps that kills you because high DC voltage does nothing to you since your body’s resistance is really high. If you have AC then your body behaves like a capacitor and by doing so it lets much more current flow through. Then, usually, death is caused by milliamperes of alternating current flowing through your heart. So you can have 120V DC between your left and right hand with no problem, but certainly not 120V AC. So we could say it’s Tesla that kills you, in fact it was one of the main arguments against AC current in the first place, its safety. It’s the right frequency that kills you.

UK resident here. Switches on sockets is crazy - whenever I've replaced any, I've replaced them with the non-switched type. They're freely available here. I don't know if there's "code" here which forces their installation by builders but as you can get non-switched ones from B&Q (retailer) I doubt it. The UK plug is quite ingenious. Aside from the fact that the cable exits parallel to the wall which makes for the "foot hazard" if left lying around unplugged, it also means you're less likely to be able to trip over a cable when it is plugged-in as it immediately falls downward. Or, if you do trip over a cable, then less likely to rip the plug out of the wall. And if you rip the cables out of the plug, the Earth cable will be the one pulled out last, so maintains the "safety" element. Also, the earth pin is longer, which opens the shrouds inside the sockets for Live and Neutral (which are normally closed to prying baby-sized fingers), and both Live and Neutral pins themselves are shrouded so that you cannot touch the contact point while it is actually connected to the supply while you are plugging one in (or unplugging). But yeah, they're a bastard if you tread on them and they are larger than most other countries' plugs. Ring mains circuits comes from the post-war era, and was a cost saving measure at the time. It was dressed-up as another safety mechanism but doesn't really hold water APART from the fact that you have two paths for earth which is a technical win... not sure how often it's tested in practice though. Plug-based fuses was originally intended to ensure no single device could draw more than the 13A max and therefore overload the ring, but these days they're irrelevant because, in the event of an overload, the plug fuse will not fail before the consumer board RCD trips anyway. Thanks for the video - it's a fascinating insight into the US system which has always baffled me. I actually wonder if we're due some regulations changes over here to accommodate the low-energy devices we are starting to see. My house is less than 2 years old so has LED wiring everywhere.

In China they also use a AU/NZ style socket for some devices but they mount it upside down so the earth pin is at the top. China does however also use the US style plug that but at 220 volts. That socket tends to be a hybrid socket that will also take a 2 pin European plug. old house here in NZ I used to live in used a bigger version of the British style plug for the stove/oven. This was due to that socket being higher Amperage than the 10 Amps of a regular socket. Lot of the sockets at my work also have 3 phase plugs with 4 round plugs (3 small - one big) they need to supply higher amperage or voltage for industrial machines.

You have to separate the neutral and ground wires on a sub panel or after the main breaker if that is located on the outside of your building. Make sure to remove the green bonding screw in the sub panel.

For anyone commenting on how “bad” his panel is, I’ve seen WAY worse when old buildings upgrade the circuits without upgrading the panels. My parents 97 year old home had so many wires in in before upgrading to a full 200 amp panel it was literally dangerous. Dual circuit breakers (yes they are real) WITH two wires in each circuit because there was just no room for more breakers being a 100 amp panel. Oh and nob and tube wiring which often was wired incorrectly and electrified the device instead of grounding it! In the US older homes can be an electrical fire waiting to happen.
@letsseewherethisgoes 3 роки тому
Yeah I would consider his panel damn near pristine compared to.... well almost any house I've ever lived in. I mean, you can tell what runs where, it's labelled, wires run in logical lines! Mostly all installed in the last 50 years! No immediately obvious fire hazards! I would be downright pleased to have a panel that clean. I've lived in a house with 3 distinct generations of wiring systems - the original knob & tube with cotton sheathing, then some rubber-sheathed/cotton wrapped, then some 90's rubber sheathed/rubber wrapped, all fed haphazardly into a semi-recent 100A panel. You can tell that the skill of the person doing the wiring went down with each generation of wiring too - the original stuff was actually installed decently. The later stuff was a bloody nightmare. It's really common to see houses with a mix of Aluminum and Copper wiring, or with the original knob & tube running into the original fuse panel, which was unhooked and then fed from a 60A breaker on a new panel - leaving the old stuff as is and just installing anything new into the new main panel.
@Cyanide300 3 роки тому
Yeah it honestly looks like a pretty normal 200 amp panel, just with more circuits than most single family homes have. I've seen MUCH worse wiring jobs. And honestly, how much does it even matter if the wiring in the panel is kinda messy? It's covered for a reason, and you shouldn't be messing with that shit unless you really know what you're doing anyway. In which case you'd probably know enough to kill the main before digging around in there.

The switch is just one extra way the circuit can be broken without having to pull the cable out of the wall. Some cables don't like this (like the UK), but also if the cable is in any way damaged, burned etc, this allows the circuit to be broken without touching the cable. Situational for sure, but in those situations it's good to have it

As for the dryers, its 120/240v and 120 is for the... Control board, any lights, and a motor to spin the drum. Ranges use 120/240 for controls, and a fan motor if it's a convection oven. Same for wall ovens, too. As an electrician, I'm required to provide a 4 wires connection to these appliances, from NEC 1996 to now. Pre 1996, the ground was also permitted to carry the small current from a light or timer motor, on account of the larger wire being less likely to be damaged. The circuits were typically ran in type SEU cable, where the neutral is wrapped around the hot wires under the jacket. Modern large 240v circuits are often ran in aluminum SER cable, having three insulated wires and a bare ground.

Its easier to switch on and off than unplugging/plugging the entire cord in tight/hard to reach spaces. eg, a Smart tv that is on standby when powered on...if the tv hangs and you want to do a cold startup and the cord/switch is hard to reach, using the switch is easier than unplugging it and fumbling trying to plug it back in just by feeling it.
@rezemika 5 місяців тому
I studied electrical engineering in France, here we just have 230V in house. The transformers output three phases and a neutral, the neutral is grounded. Each house in a neighborhood is connected to one of the phases and to the neutral conductor, so we have 230V between neutral and a phase. For bigger installations (industries or big buildings), we have the three phases and neutral, so depending on how we make the connections, we can have 230V or 400V (between two phases) for each circuit. But 99% of our devices are made for 230V. It's really intersting to see how it works in other countries, so thank you so much for this video, and thanks to all other people posting details about theirs countries in comments! :) I'm also really surprised to see such big powers for a single house. My house has a 3kW subscription for two people, and here 3 to 6 kW is really enough for most houses/families, except for really big houses or for people using a lot of machine-tools...

@brianmason9803 3 роки тому
It makes a lot of sense where you have a huge variety of distribution situations. In the UK we have 3-phase, 440/240v (delta/star voltages). Most households are 240 unless a 440v is specially run for a workshop etc. I love 3-phase as on a 'star' connection, if you get all phases balanced out there is no return current and therefore no return current volt-drops. I think our choice of voltage goes back to wartimes when copper was in short supply. For the same reason our house power sockets are wired in a 'ring' format where the wiring comes back to the fuse board completing a ring for each conductor. Again, you can cut copper size for the same volt-drop. Nothing unsafe about your setup though, although you have to be careful you don't find a socket outlet connected between the two phases.

In the US the main thing was lighting when electricity was introduced to homes. We used to have a 30 amp 120v system as a standard originally. It went up to 60 as more appliances and lighting were used commonly. We didn't need 240 because no one had electric dryers, central a/c or electric water heaters. 120v was the norm, so when we needed 240, we already had the standard for lighting and small appliances at 120. We would have had to toss all our 120v small appliances and light bulbs which have specially engineered tungsten steel filaments and change all of those to withstand 240v to go with our large appliances, which many people could not afford. As an electrician, your video was really thorough. Your QO Square D breakers clip to a rail. Some of the best for residential. The ground and neutral are bonded at the service per code but separate in the field at the outlets. To avoid as much of a shock when plugging something in, make sure it is off. That takes the load off the circuit. Your example had someone plugging in a lamp while it was on. Don't do that. Shut it off first. I don't see anything wrong with our receptacles. I would never plug in an electric dryer or stove with the circuit breaker on. Many people need this video to understand the basics of having the convenience of electricity in your home. Great job.

On that switch near the outlet: they sell mini devices at Amazon to cut power selectively which I use on things that don't have switches on them. For things like a blender, they do have an off switch but once I had a blender that had a trace of liquid that slid into the buttons (or had some electrical issue with it). One day I was sitting at the other side of the room, the blender just started sparking... if I had that switch by the outlet, I could've ensured no power went to it. Fortunately I was home.
