- In this video I discuss which part of an electrical panel can shock you while working on this panel live.
Watch the Full Live Panel Wiring Video : • Electrical Panel | Wir...
When wiring a breaker box, the most exposed part of the panel is the bus bar. The bus bar is a conductor that distributes electricity to the various circuit breakers in the panel. It runs down the whole panel from breaker to breaker and is typically made of metal, making it easy to accidentally touch. If you must work an electrical panel live, be very careful to avoid touching these busses with your hands or with any tools.
When dealing with electricity it is essential to consult a licensed electrician for all electrical work and to follow all electrical codes for your specific location. Electricity can be extremely dangerous. This video is strictly for your entertainment! - Навчання та стиль

![How To Install A New Circuit Breaker DIY [AVOID Electrician]](/img/tr.png)
Where I work at we have What's called the one zap Friday. We all take turns and getting Zapped by 110 volts so we can build up an immunity to electrocution
Please stop doing that. Your not building nothing and your encouraging the young ones to be reckless.
Hey, that’s how I started out. After four years I’m up to adding a 2 oz shot of pure electrons to my cappuccino every morning.
@@aleonyohan6745 it's all fun and games till Brad goes cold ❄️ that's gonna be on you.
But whatever. We're in an age where theirs all kinds of quality meters + testers for anyone to get hurt.
@@cesarflores8450 Why would someone else's stupidity be this guy's fault? He's right if you're that dumb to be getting zapped and you die oh well
At your 5 year mark you should be able to Jump start car batteries With your bare hands.
I had a foreman say, "Electricity doesn't kill you, but being cocky does."
I'd say both can kill you but I get what you're saying.
Haha nice. I’m using that in my next video.
I haven’t been working with anything love though… 🤔
Naahh!... I'm pretty sure it's the electricity...
You have old electricians, and bold electricians. Very rarely do you have both
@@michaelcormier2109idk. My dad would touch live telephone wires on houses just to be able to say to his son, "Watch this"
Complacency at its finest
this will absolutely kill you if you touch it with both hands
Very safe as long as he only uses one hand
@@dertgild maybe if his shoes are well insulated and not wet, I still wouldn't count on those odds
Not gonna kill me? Guess again.
@@dertgildyou obviously don't know what you're talking about
I would really be scared to work with someone this complacent.
What does complacent mean ??
@@mclovin240o9 google it? You have the entire internet right there
Huh?
@@mclovin240o9I think you can Google the word...,🙄
I'd be afraid to know someone this complacent, because his carelessness will kill someone some day, and I don't want to be anywhere near him!
Also a great way to find out if you have any holes in your gloves 👌
Only if you are touching something else. If you have rubber sole boots on you can bare hand touch all that without getting shocked.
@@johnh8546I’ve seen someone barehand a power line cable wearing flip flops standing on a wooden stool I swear to god, yes it was live and it was sparking as he was trying to connect it to the other power line cable lmfao
😂
@johnh8546 yes except the issue is that's all fine until your elbow or gut touches the panel.
😂
Those gloves are a _secondary_ safety tool. If you use them as the primary safety mechanism, and they fail one day, you're in a world of hurt.
Complacency kills.
You usually put those over the eletric rated gloves but still he is braver than me to just be touching all over that
Geniuses the meter is not installed in this video this is a new residential install
@@scotts1668 Sure looks like the meter is there, and it even looks like the main is on. Don't get me wrong, I've done plenty of sketchy stuff in my day (drilling/tapping lugs onto live bus bar standing on wooden boards, with electrical tape wrapped tools; this was long before arc-flash and insulated tools). Guys that work around it enough do get complacent...
@Jester The Jynxster lmao how did I miss that meter?? Good call sir I did notice the main was on but I just assumed from the one breaker installed it was a new construction and not live yet.
The title says live panel. So either way he's advocating for such complacency around live panels.
The first thing I was taught in electrical school was "If you don't have to work on it live than don't.
I was told master electrician get killed more often appreciates for this reason... I'm a master now and STILL have the apprentice mindset when it comes to live
Exactly! It's not just the electrocution risk, but also the risk of shorting things, especially in breaker panels. Shorting something out can burn or even blind you due to the arcing and sparks. It also can mess up your tools!
Then ur not a real electrician, fire fighter work on real fire .

Most electrical deaths happen on 120/240 so "it won't kill you" is really showing how little you respect the Electrical you work on. I have been hit by everything up to and including 480 and i can tell you i lived to learn my lesson but i definitely found a new found respect for the dangers of what i do. (Note: Am an electrician)
Dude is liking the comment but is going to get newbies killed. Hey you got some likes at least humanity thanks you👍🏻
Exactly!
Most electoral deaths? Happen with dc power. Soo shut up 120 won't kill you . Nor will 240 . Trust me I've jolted my self soo much
As an electrician you are more likely to die from a fall then from getting shocked.
@@EskimoBENNY 💯 more chance of falling of the steps lol
“Yeah I know there is a breaker to kill the power on the bus right in front of my face but that’s overrated.”
Looks like it’s a 200 amp breaker, I don’t think it’s overrated at all!😂
What idiots are thinking: let me grab my winter gloves so I can touch the buss bar too 😆
I just did it and it’s safe af! Only felt a little tickle through my chest for a few minutes now I’m all jittery 😂
@@murkyturkey5238does it work better than caffeine?
Exactly
He's wearing freaking mechanics gloves. Dont
Yeah I googled the gloves based on the text on the finger and was like - these are just yard gloves...
Dude, I have worked on a whole lot of electric over the years, and never once did I purposely touch something with or without gloves. You’re nuts my man lol.
I do hvac and I always just treat every wire that isn’t 24v like it’s hot bc you neverrrrr know
Test for voltage first folk
Even 24 can get you!
@@davidfriction7170 24v is a little shock but that 240v zapped me so hard I felt like pooping
Wet, 24v will knock you off a ladder.
@Dante Mariscal I had a single leg of 480 get me on a RTU last summer. Felt like Tyson punched my hand.
I would add a HUGE caveat saying "you probably won't die" if you say stuff like "it's not going to kill you" you're putting way too much confidence in people in the internet.
Yeah. Air on the side of careless…? Good one. And I don’t get why they are working on a live panel anyway. Just turn off the main breaker at the top. No? Works in my house. I guess he just wants to prove what a badass he is.
Second this. Poorly worded by him, probably should add a correction on screen and reupload. It’s worth it to decrease the chance of misleading people about dangers
@@caseykittelmaybe he had to keep that 2 pole load on? I've worked in many many many live panels due to loads needing to be kept on.
Yep, depends on how the electricity finds it’s way to ground. If it runs up one arm through your chest and out the other arm it can definitely kill you.
@@caseykittel error*.... Ffs
Unless it's a life safety system,there's no reason to work live
Darwin Award candidate.
I find it funny when people say this about working live, which who probably never serviced electrical. Easier said then done, obviously new construction its not live. Ive been a service electrician for 21 years and have to work live alot. You gotta understand when your doing big corporate business buildings ya cant always shut down power, networking lines, computers, lines they need to operate etc... cant be shut down to do they work, they would have to close the store down. Not always an option.
@@TimboStang71 I’ve worked on many critical systems and you know what you do? You organise temporary power and everyone goes home safe. In Australia there is almost 0 necessity to work on anything live if your not working on the network. Unfortunately people in the states seem to not really care about working with the power off and seem to care more about how they’re going to inconvenience a business vs working safe.
@TimboStang71 OSHA doesn't make an exception for a company losing money. You have to work out a time with the company to shut down power.
If it’s a system that can’t be depowered then it should have a distribution board that can be worked on whilst live without shock risk. Such things exist, perhaps not in the USA, but obviously there is a price premium. That’s why the likes of OSHA impose big fines, to try to influence paying up front for safety rather than be fined later.
They aren’t “opposite phases”. It’s a single split phase. Single phase off of the primary into a winding, then on the secondary, it’s center tapped for your neutral and each end of the winding are your “hots”.
This is true but it is kinda pedantic. He also said single phase 120 but it's single phase 240. And after he fingered that Bus bar he said it won't kill you but 100-200v is what people die from most often. Basically nothing in this video is right lol
I'm not an electritioan, but I thought those are called legs.
@Michael Merryman no, voltage isn't what kills. It's amps that kill. Human body can withstand a lot of voltage.
@@saywhat6632 I've been an electrician for almost 20yrs. And it's a combination of voltage and amperage. Although amperage across the heart is what kills you the voltage still needs to be above ~40v. But my point was that most people who die from electrocution, do so from 100-200v. That's a fact jack. It only takes .08 milliamps across your heart to die so the amperage from any electrical system is enough to kill you, so fingering a panel while power is on isn't a great idea and him telling people "it's OK it's only 120v youll just get shocked" is stupid, wrong and dangerous. Amperage Essentially is what kills you but there isn't a way to limit amperage to the point it's safe, it's more important to pay attention to where you are in relation to live power. It's best to work with one hand when possible to avoid grounding the other and touching live power at the same time sending voltage across your heart. Wearing boots that are insulated again to avoid power from running through your body. You can endure alot of voltage and amperage without significant problems if it travels say between the tip of the finger and your knuckle which is why we try to work with one hand when possible but that still doesn't mean bad things can't happen. Pay attention to what ur touching and never fingerbang a live Bus bar and you'll be good.
It's a single phase at the distribution point, but at the panel, it's two phases at a 180 deg phase shift.
The Hole in His Glove: 🤡
He told you already that hole will only get his attention lol clam down fool
OSHA WATCHING HELLA CLOSE IN ON THIS ONE 😂
Won't kill ya but it will get your attention is such an understatement.
And totally WRONG!!!
“Laughs in arc flash”
120 and 240 arnt likely to arc flash I mean anything is possible its just very unlikely to happen being electrocuted by those voltages however is much more likely so still be safe either way. I personally work right now around 1500 volt dc battery banks, 480 volt hvac units and disconects and 35000 volt lines that connect into a substation it's technically the load side of things so we are contracted out by the utility to work on this stuff and it's safer than some of the resi jobs I've done because of the danger that screwing up with these voltages presents. No matter what you are working on be safe take precautions loto and pay attention to your surroundings.
It's not going to kill you but it'll get your attention is the most electrician answer I've ever heard
They aren't actually opposite phases. They are coming off a split phase transformer, center tapped to ground.
That's what opposite phase is, though? The two waveforms are opposite polarity, which is equivalent to a 180° phase difference.
@@Dwonis In this configuration you get power from a center tapped secondary winding to neutral. It is a single phase but because your center tapped, your force each leg to be 180deg apart. In a traditional multiphase system, power is across multiple unique windings and is 120degrees apart (A, B, C).
That’s correct it’s poly phase
Yeah it’s a weird situation where it’s really single phase but also kinda two phase lol
Split phase is opposite phases, 2 phase power has one phase 90 degrees out of phase, and the use of capacitors has made 2 phase power mostly obsolete.
This behavior will kill you someday. Never become comfortable touching something that can kill you. One day you will be thinking about something else and will reach out and touch that without gloves and that will be all she wrote..
Yet linemen do it daily but damn hose facts
Don’t get in the habit of trusting your gloves this way. He also said it won’t kill you, but the severity of a shock has little to do with the voltage. Path of current, amount of current, and time spent in contact with the circuit. All it takes is .007 amps across the heart to stop it. Electricity doesn’t just take the path of least resistance in the body. It takes all paths with with the current being indirectly proportional to the resistance in that path.
"Its not gonna kill you"
Yeah, I'm not sure about that.
"It's not going to kill ya" was the last thing we heard him say as he proceeded to seize and collapse to the floor.
🪦
The service is right there next to the panel. Turn that shit off, and don't ever touch a hot bus bar. This guy is going to get someone killed.
When a drywaller decides to do electrical.
If everyone had the confidence of residential electricians, there'd be a lot less people walking around with ten fingers.
🤪
Just wait till this guy gets hit by a 480 volt shock or arc flash and let's see how cocky he gets after that. Or even better I wanna see him working in the rain with wet hands on a live 240 volt service. Goes from miliamps of current hitting you to hundreds of miliamps of current hitting you possible amps depending on the situation. This video is seriously wrong from every angle.
It would most defiantly be able kill you. Depends on the difference in potentials ,thus how much current could flow through you
I always say it *probably* won't kill you. I don't feel too safe or confident with a "probably"
Any voltage could kill you depending on the amps. You have to be in a very dumb situation to be killed by 120 in residential. Like a tight space and you’re hung up to ground somewhere
@@frankw3606 Oh really? Could 5 volts kill you? How about 0.1 volts? It isn't that simple. It does depend on the current thru you which depends on your body's resistance. So it isn't just the current, i.e. amps.
@@tangowally yes it’s the current flowing through your body that will kill you, but it’s the voltage which will drive it through you. If you imagine voltage as the pressure 12volts isn’t enough for the current to flow. Hold on to a car batter at 12v that has a 400ah Capacity and I bet you’ll be just fine
Correct it could kill... But most likely won't. Still not worth touching it unless you have too.... Even with gloves. Trust me, shocks hurt, I know from personal experience.
If you touch a hot with one hand and a neutral with another, it can result in an ER visit or death.
Oh man. Probably death. You’ve got 100-200 amps running through you. You’re putting a lot of faith in that main breaker. Or u just don’t have any insulation on your feet and it’s a wet day. Touching the hot alone could kill you.
As an electrical engineer, I still had anxiety watching this.
If you make a habit of touching everything even though you're wearing a gloves, it's only a matter of time before an absent mind teaches you a lesson.
Kinda like running stop signs and speeding.
@@daveyt4802 I meeeean sure??? in the sense that they're both kinda dangerous in a sense. But the point wasn't that he's doing something dangerous, the point was that he's doing something which is only dangerous if you don't have proper PPE on, but if your normal mode of operation is to do this, then someday, you're going to forget you don't have PPE on, and then it's going to be dangerous. Speeding is always dangerous, regardless of any other context. I guess I could see an argument that running a stop sign is only dangerous if there are other cars around. So sure, I suppose I see that analogy.
He probably also have special safety boot's on too. So it cant pass thru body.
@@DoNE021 only if he never needs both hands to, say, hold a wire in a breaker while tightening the screw
Isn't it technically not 2 separate phases? It's one phase split in half between the two bussings, hence "split phase"
Correct. This is one of the most common misconceptions.
That is correct 👍
Depends on how you look at it. If you are at the panel with and oscilloscope, it's definitely two phases. If you ask the power company the residential transformer is only hooked up to one phase of the transmission line.
@@WorBlux distribution line not transmission line and depending on line V it can be hooked up to two phases and still be 1ph
Being ARROGANT and touching it with gloves is childish & foolish.
The gloves are a safety device, not for daredevil antics....children will mimick what they see...
Fortunately it's cold weather as indicated by his jacket/coat. Sweat soaked gloves in hot weather are good conductors.
Insight!
This man reckless. People die on 120 240 all the time. It's no joke.
You can touch it as long as your not touching anything else or ground …. Highly not recommend but yea 😅
....and whyyy is it on? 🤔
Only one 240V circuit there. Needed it for...Defibrillator?
I'm a retired building operations engineer...in 16 years in the trade I saw 2 people killed and several others severely injured. In a couple of instances, somebody got stupid. But in several others, they were doing everything right ,and still, bad things happened. You have to be careful, attentive and prepared. Always.
My phone vibrated when he was touching the live panel and I actually died a little inside
Gloves?!? Those don’t look insulated
Leather doesn't conduct electricity unless wet 😉
Jesus at least say you had rubbers on underneath the leather... otherwise you gonna get darwined
@@sulfuricanaljuice3994 He's obviously not the sharpest pencil in the drawer - AND NOW the entire internet knows his IQ level! LMFAO
An electrician that calls a split phase system "phase A and phase B" 🤣
I thought that’s literally what it’s called. What do you call it. Sorry I’m a commercial electrician do I don’t deal with this stuff lol
Ohhhh maybe because you mean it’s a single phase system that’s center tapped to crest two “phases”
@@jakebackpack8292 no, it creates 2 “poles” or “legs” of the single phase.
@@jakebackpack8292 you are used to 3 phase labels where it's ACTUALLY different phases, but this is just different legs of the same phase from the center tapped transformer
And the funny part is that he calls it single phase right after.. like shouldn’t that tell him something? lol
I got Knocked out cold when I was 15 . I shut the mower off by pushing the little metal flap onto the spark plug. Came to with Grandma screamin. Scary
It's even more fun on the 3 phase panel when you got 3 different phases in a row and repeat over and over especially when it's got a. Delta high leg on the b phase.
It doesn't have to be very high voltage to kill guys. You may just be the unlucky one that the shock disturbs the heart rhythm and pop you are gone. Be careful
Old school electricians used to touch 120v all the time
@@Robmancan1987and we wonder why electrocution was more common before better saftey standards were put in place. I still know cowboys to this day who are luck to be alive and plenty that didn't make it. Don't be stupid.
The lower the voltage, the higher the amperage. You are more likely to die with a lower voltage. Amps are the killer. Don’t forget the PIE Chart. Electricians know what I’m talking about.
Amps kill, 50 milliamps can stop your heart
Split phase is not 2 phases.
Yes. It is single phase. But one side is called "A phase" and the other is "B phase. If you add the third phase " C phase" you have 3 phase.
@Daniel Houghtelling No, it's a single winding of a transformer neutral point is in the middle of that winding, not 2 windings (phases)
I remember when I worked on a live panel. I didnt know it was live though. 480vac three phase. 4-4soow cord supplied disconnect. I got complacent and believed the person who said they had cut main power. I removed the 4-4 from the main lugs no gloves and somehow didnt get bit. Pulled the cord to remove it from the panel out of the cord grip. All 3 phases came together. Wicked arc flash. Lucky to be alive
As an European i see no any danger in 110 volts.
Keep getting zapped lol
Not an electrician, but iv taken classes. I treat All electricity like it could kill me unless it’s under 24v…even if I have gear on…
to me, working with electricity should be like working with a firearm. ALWAYS treat it like it’s loaded and respect it.
Stop giving out bad information. This can shock and kill someone. Learn about NFPA 70E standards..
Get your attention it will. Only time I've ever been knocked unconscious and that feeling never leaves.
Got bit by 480 on the hot rail. Became a janitor the next day.
Always have the main switch off when doing that. Then the two places he’s talking about will have no voltage as long as the switch is good.
People like that need to be taught a better lesson. Just because the gloves protect you, doesn't mean touch everything you shouldn't, just because you can
Been bit by 277 doing HVAC. Had a beautiful arch mark on my forearm and made a complete circuit across my chest left arm was on the suction line and I accident grazed a fan relay while I was on the top of a 6 foot ladder. First time with 277 left me afraid of wires for a while. Been bit countless other times but electricity kills and is no joke. Check twice, use NCV on a meter and check each leg to ground. Seen a broken disconnect only disengage 2 out of 3 legs as well
Yeah, you can taste it. Then it will make you sit down, wont it? That's a mistake you only make once. I learned after just once.
It’s single phase. This is phase A and this is phase B. This makes perfect sense 😂
Plenty of people have been killed by 120v, especially working in live panels on a rainy day.
This a thousand times this. So many guys I know who working near wet equipment or had drenched hands from sweat or rain people forget that resistance is a very important variable.
Here comes the receptacle changers with their expertise 😂
"Yeah we call up the power company and have them shut off the feeder for the whole neighborhood before we click the reset button on a GFI, its standard procedure. Electricity is no joke, but we sure are"
Even if you're wearing gloves, you should not be physically touching it.
Jurassic park comes to mind... "why touch, why does she always have to touch"
There aren't 2 phases. It's all single phase. 1 bus comes from one side of the transformer, the other bus comes from the other side of the transformer. If you use half of the transformer you get 120v. If you use the full transformer you get 240v. Both single phase.
They are two phases... In wave descriptions, phase is simply the timing difference between the peaks of the wave forms with the same frequency. The highest voltage potential on each leg is offset by 180 degrees or 1/2 a wave period (1/120th a second in the U.S)
And if you add two sine wave of the same frequency and amplitude, you end up with another sine wave of the same frequency with the amplitude determined by the phase difference * the original amplitude.
sqrt(((1- cos(180deg))^2) + (sin(180deg)^2)) = 2. 2x120=240.
In some buildings a panel like this might be fed by phases 120 degrees apart -- But once you are standing at the panel, it makes little difference.
sqrt((1 - cos(120 degrees))^2 + sin(120 degrees)^2 = 1.73X120 = 208
The reason electricians like to call them poles is so they don't confuse them with rules and procedures for three-phase systems.
Why is he working live?
Feeding a sub panel that powers the house a family is living in. Wanted to let them keep using power while making up the panel for their new addition. See full video in pinned comment for more detail
@@wireyouyeah, no… f that family. They’re going dark as well or I’m not working on it.
You can touch one phase at a time if you’re ungrounded. Touch both phases at the same time with separate hands for a funny tickle.
He forgot to tell you if you have a tiny hole in your glove it can shock you!!
Only trained and Qualified electricians should open the panel.
💯
Literally touching a hot buss with Home Depot work gloves not even insulated gloves😂 this is exactly how people get killed thinking their smarter than electricity
Man ... He sure trusts those gloves
Comin hot is one of my favorite things to say daily, great video guys.
Just got shocked by 120v and had to spend a week in the hospital, be careful out there
How you doing as of now? Did you complete a circuit or something? Im curious as to what happened and how you ended up in the hospital for a week. Not doubting, genuinely curious. Hope youre doing alright.
@@goosenotmaverick1156well any time you get shocked you are completing a cuircut with your body in some way. If I had to wager it hit his heart and that's why he was in the hospital could have even caused permanent damage to it but that's just a guess.
@@jsb7546 oh I know what generally happens, I'm an electrician, we are well aware of the unfortunate possibilities of getting shocked, or worse, electrocuted. It can cause all sorts of issues even if youre not killed. It can leave lifelong effects on your heart rhythm and all sorts of bad juju. I'm just hoping the OP is recovering well. And I meant complete a circuit in the sense of carrying a significant load across your body, not just routing minimal potential to ground. Sorry if I was not clear, I generalize a little to carelessly sometimes, so my apologies there.
As long as you're not grounded you can touch a live wire all day long and not get shocked.
Until someone walks up and taps you on the shoulder. Also, if that door is not propped open, you're at risk.
Not exactly true. You heard of static discharge? Why does a helicopter lineman have to use a grounding rod to bring themselves up to potential before touching the line? The same thing applies when getting off the line - a transient discharge could still be lethal, even though it's not going to "ground".
Doing electrical work is like playing hide and seek with death you want to find death before it finds you.
You 100 percent can touch a hot bare handed. Just don't touch the neutral or the ground. I'm not saying you should or to try it but you can.
Yeah, I kind of think you’re missing the point of the persons feet being in something that would create a ground like standing in water or a wet surface or barefoot… you’re 100% comment falls short of explaining that part
You can only touch a hot if you’re perfectly insulated. Which most people absolutely will not be. Touching the hot alone will shock you 99% of the time.
@itomalty1 If you’re a bird you can.
Let’s say it’s 100 amp service. That 120 volt can definitely kill you. 120 from the buss bar is different than 120 from a 15 amp circuit
How is it different?
in this situation it's irrelevant
the body is not conductive enough to even trip a 15 amp breaker
so touching the main bus or after the breaker is the same
difference will be if you drop a screw driver...that will be different
@@maxmerton It isn't
I don't car if you grab it off the transformer, it's still the same potential
@@kstorm889 potential is different than amperage…. Amps is what kills you not the potential. Static electricity is like 20k volts, it doesn’t kill you because there isn’t really current.
When you have a buss bar next to another buss bar you’ll be liable to touch both making a path for 240 volts at say 100 amps meaning 24000 kw of energy…. You’d light up like a bug zapper if you were stuck to that many kw of energy
Anyone else pucker watching him fondle the energized bus bars?
Stuck my finger in an empty breaker slot when I was like 7 I’ll never forget that big Darwin Award for that one
Looks like a demonstration/explanation I gave to a Hispanic painter once when he stopped to watch me land a panel. The look of terror in his eyes when I touched the bus made me laugh so hard. Know what you're doing and how this shit works and you'll never worry.
😂💯

Gloves can have holes in them dude
You need to find a new profession.
Walking on carpet with socks on will get you a shock… this is a little different lol
Watching him poker his fingers in there with the gloves, every time he touches something I get flashbacks. Nope. I learned a long time ago I'm not an electrician. Now I'm all tingly again.
Theoretically....you can certainly still touch the bus bars separately ungrounded and you'll be ok.
I think we should be able to take out life insurance on strangers 🤣
💀
With your left hand? No. That's your heart side.
You see the breaker that’s all the way on the top, that’s your main disconnect. Open it and the bus won’t be hot lol
You will be fine as long as you yell “ Shazam “ 😂😂😂
I've been shocked 100s of times. Generally there is negligible load on a circuit you're working on, but if it's at anything like 1 amp and up because of a current draw on the branch, and you make a better potential to ground your gonna be closer to death, than on an unloaded branch circuit.
Just to clarify, touching one will NOT kill or shock you, UNLESS you are grounded or complete the return to source (i.e. primary earth ground p.e./p.g. on prints or the second side of the source in this case both buss bars at one time) I won't get into the weeds on what shoes are more at risk for connecting you to earth ground. Touching both sides of the buss bar at one time was pretty dumb. Those are regular "work gloves" and not even the old "00" glove liners and leather glove protectors. If he ever works and gets really sweaty, he has a lesson coming screwing around touching two buss bars in work gloves. If his work gloves have steel filings or shavings, he could be the next Darwin award winner. All those ground wires rattling bumping against him, once again, are the potential learning one day. Same thing about the water myth. Water is actually an EXCELLENT insulator until it becomes electrolytic water ( water with electrolytes suspended in it). Deionized water or distilled water is an insulator. 120vac probably has killed more people than any voltage. 1. It is more common. 2. All conditions are not the same. The very reason why GFCI circuits are in wet locations. People used to die, with frequency, in pre-code bathrooms and flooded basements. Think the old movies a radio falling into a bathroom. It caused an industry change. 3. Everyone does not have the same health factors. 30mA is all it takes to cause a-fib. Once again, the cause of the whole industry of institutional defibrillators. He needs to learn electricity before putting this crap out there. Lastly, I literally had a contemporary killed on a 277 neutral on a shared service (bad installation). Bad information. I would not trust this guy! 😡
As an European, Im really surpriced that you have open live vires and rails openly accessable.
You freeze for a few seconds on 240v
You turn into a statue.
I did HVAC for 4 years and they never went over something like this. Always cool to learn something new
To clarify, US residential electrical tranformers step down line voltage, usually only grabbing one phase (of three), to 240v. It is a split phase, meaning the neutral is bonded at the middle of the wound coil, and the half phases are the ends.
So rather than 0-120, 0-120, or 0-240, it is 120-0-120, and technically one side is negative in scale but it doesn't matter for consumers, and 0 represents ground, or neutral, which are bonded at the service.
Yeah it was historically done because 240V - i.e. the rest of the world - would be more expensive. But then we don't user Aluminum cables here as well.
@@darknase The 120V standard was in the U.S. as a safety thing, an the fact when the standard was introduced electricity was mainly used for lighting, and 120V is plenty for that. Split phase came in when they realized 120 wasn't enough to drive power hungry appliances, and it was the cheapest way to run multi-voltage systems to the home.
The bus bar won’t shock u if your not grounded I touch it before with my fingers
Only get shocked if you're grounded or touching both phases. You can touch the buss without getting zapped
I'll never forget in trade school when they said as little as 30 Volts can stop the Human Heart...While I'm working with guys cutting dead shorts to trip the panel out with old Live knob & tube. SPARK SHOWS 💥⚡️💥
Professionals turn it off before working on it. They certainly don't go touching energized parts, even while wearing electrically insulated gloves.
A neutral bar definitely can and will shock you. It can’t there because he doesn’t have any current coming back on it but the worst I’ve been hit is on a neutral bar.
The whole time I’m looking at you I have anxiety😂
"Two separate phases, this is single phase"....says it all.
"It'll definitely get your attention" yeah, i hope live current from a breaker would get your attention 🤣
The biggest lie is “that isn’t gonna kill ya.” It absolutely can. 120v is one of the voltages that takes the most lives every year, precisely because of this cavalier attitude.
To be honest I've always worked on electrical panel boxes with the power still on, after I turned off the Breaker to the circuit I'm working on, yes I've gotten my fair share of shocks, but its because i believed other electricians when they told me that the line is dead and no power only to get a nice shock when attempting to replace receptables or lighting fixtures. Now i take my tester and check for voltage regardless of what one says. I've came across many mislabeled or not label breaker panels.
