At some point, most of us electricians have received a shock from touching a hot conductor and something that is grounded. Some of us have also been shocked by touching 2 different hot conductors! But what about a neutral conductor? Is it possible to get shocked by the neutral? In the latest episode of Electrician U, Dustin talks about this phenomenon and clears a few things up.

As we have discussed in previous episode of Electrician U, in order for electricity to work as we intend it to, it must travel in loops. In a 120v circuit, for example, current leaves on the hot conductor, travels THRU the load, and returns on the neutral conductor. In this way, the loop is closed and current can flow. Break either the hot or the neutral, and current will no longer flow and whatever load you have in the circuit will not operate. The same process is true for a multi hot (240v with 2 hots for example) circuit. Current will travel out on one hot, THRU the load, and back on the other hot completing the circuit and allowing the current to flow.
To receive a shock, you must be touching something that is energized AND something else that allows the loop to be completed and current to flow. So, the hot wire and the ground wire or the hot wire and a neutral or the hot wire and another hot wire. Any of those scenarios will allow current to flow and you will receive a nasty shock! So, with neutrals, the same rules apply. You must be touching the neutral conductor AND something else for it to SHOCK you! Imagine if you were touching the side of the lamp screw shell with one hand and something grounded with the other, you will receive a shock (in addition to having the lamp come ON!). But if you were to touch the side of that lamp screw shell and NOTHING ELSE, then the loop will NOT be closed and current CANNOT flow.
You could potentially receive a shock from a neutral conductor if it is not bonded to ground at the service point. But again, to get shocked by the neutral conductor, you would have to be touching it AND something else so current can flow. It is possible to get shocked by touching two neutrals. If you were to touch the neutral coming from the side of a screw shell from a light bulb and the neutral GOING TO the panel, you will most definitely (if the circuit is energized) receive a shock. But this is only because you are completing the loop! At the point of the screw shell, the neutral conductor touching it is essentially the same wire as the hot as things will be travelling thru the filament of the light bulb. So, again, you are just completing the loop and allowing current to flow.
As a good rule of thumb, when working on something that is energized, don’t touch 2 things at once! Some older electricians keep one hand in a pocket, so it forces them to not touch anything with it. Check your boots and make sure they are solid and make sure you are not standing or kneeling in water. Best option is to turn the circuit off, but if necessary to work with something energized (yes there are reasons why we NEED to have it on), take the necessary steps to protect yourself.

Been there done that - with the breaker off! Shared Neutral (i obviously wasn't aware of it) across at least three different circuits in a 1950's house that saw various "handyman" and homeowner modifications through the decades. Bonus points for three-prong receptacles with no ground. I was moving a kitchen light fixture that shared a circuit with one or two receptacles in the same room, and verified all were dead. Went to wire nut the new fixture to the existing neutral, and completed the circuit for what I later found was the back bedrooms. The bedrooms' hots had their own breaker, but some psycopath didn't feel like running a separate neutral 50'.

I was an apprentice on a job with the DCR where I was shocked up the leg when I knelt down on the grass and reached in to splice in a light pole. The city engineer told the shop to tell the electrician it was off and to have me splice it in. After I got shocked and ended up on the ground the wireman came over to do exactly what he told me to do and got shocked as well. After he overcame the initial shock as well he got me up and had us call the shop who said it must of been backfed somewhere if the circuit was indeed verified off by the city engineer who insisted we did not need a key to the panel at a public facility. My legs never worked properly again. I've tried so hard to move on with my life but I live with the affects of the risk of this job and my life was forever altered. Always verify no matter who it makes look bad it's your life and someone else. Good topic to cover. I get a lot of flack when the inexperienced insist you can't ever get shocked from a neutral. Caught up in a circuit was another way to communicate that potential better or something like that. The wireman said a few things to me one of which was this would make a great story about electrical work someday. I heard he had a heart attack on a ladder just a few years later. Some of the people I worked with didn't survive or had such awful injuries.

The bottom line is that, if the neutral has potential on it in comparison to something else you're in contact with, then sure - you can get a shock (if the potential is sufficient). Generally, of course, the neutral is grounded, so coming in contact with it alone isn't an issue. I'm a little cautious with the word "touching" as someone may think that is physically touching with the hand, as described in the video. You can get a shock by touching a hot lead and nothing else if your footwear isn't sufficiently insulated. I think that there are a lot of amateur do-it-yourselfers (e.g. non-electricians working on their own homes) that watch this channel and they aren't likely wearing footwear designed for electricians. If they touch a hot, they're going to feel it as their feet are the other "touch" point to ground, completing the circuit.

@@acat6000 If you touch a hot wire and nothing else, you can't get shocked. If we're living in a pretend world where you can touch just the wire even lightning can't shock you. In fact, if you are touching a hot wire and something else that has the same phase and potential as the hot wire (like when a lineman grounds a helicopter to a live 2 million volt line so the frame has equal potential to the line) you cannot get shocked. You get shocked when the voltage can cross from one potential to another that has a potential difference, making the video misleading. The principle holds true under a narrow set of circumstances with a large number of special conditions, but it does not hold true for everyday people who will never be in a scenario where it is applicable.

Awesome presentation as usual, but I wish you would have taken a moment to warn the newer guys about shared neutrals. Even if the circuit you’re working on is off, it doesn’t mean that same neutral wire isn’t being used for a separate circuit elsewhere that is still active. This is common practice in my area, especially in older buildings.

Three way switch where they originally wired a common neutral instead of the independent neutral to the light and each switch through the travelers. The neutral from two three way switches independent and they combined the neutrals. Depending on the switch settings there was voltage in reference to ground on the neutral. I learned the hand in the pocket from my dad an electrical engineer. When followed never got shocked. Some times you just got to use two hands.

Braced against a sheet metal stud in a tract house I felt a jolt thru my shirt on my back. Checked my drop cord, Hole Hawg cord and switch.Nothing wrong with any of them. Finally determined that there was an open neutral at the temp pole that Del Webb had installed for the houses we were working on. Apparently the power was depending on the equipment ground to complete the circuit to the temporary panel.There were other subs working off this pole but nobody else had noticed a problem....yet.... I went to the super and warned him of an unsafe condition and was promptly ignored. I mean here was a plumber trying to tell him that he had an electrical problem so what the hell could I know. Right? I knew someone could be hurt so I went out and "disabled" the panel. When all the subs started screaming that their power was off and the panel was "damaged" they were out there in nothing short of light speed to fix it.....a whining plumber getting shocked was one thing but slowing down of production was an entirely different thing.... Money always speaks louder than one lonely plumber......🤣🤣🤣

Thanks for another great video! I do have one question on the open neutral. I'm just trying to understand how much of a shock a person will get if they complete the circuit for the open neutral described in the video. In that case, the person and light bulb will be be in series in the circuit, so I assume the voltage drop across the person will be less than 120 volts and hence the shock won't be as bad as it would be otherwise?
@dingo137
@dingo137 4 месяца назад
It might be a little bit lower, but probably not by that much. A 60 watt bulb on 120V will have a resistance of 240 ohms. Your body's resistance will be much higher than that (and if it's not, you're really screwed as you'll get a huge current going through you). So most of the 120V will be across you.

I have been shocked on a Neutral more than once. Multiple voltages This is about the Late 1980's with 480-volt 3-phase lighting. I am sitting on metal bleachers inside the building for a "SAFETY MEETING" and I reached up and grabbed the ceiling grid and slumped off of it during being shocked. The person giving the safety looked like he thought I was falling asleep, because as soon as I was off the grid, I regained sight. I showed them the one gray wire hanging out of the ceiling and touching the bleachers. He had some guy kill the lights and he showed me on his meter that there was no voltage from the wire to the bleachers. CYA! (Cover Your ASS!) I know what happened, and I don't believe I took the full load, although I may have been a parallel to ground. Other than that stupidity, always know where your skin is and what it is touching, and how well you are insulated I.E. Boots, Gloves ETC. BTW, YES is the answer to the video name.

You cannot get shocked from neutral. Hence the definition neutral. Without watching the video I am sure you are going to describe a way where neutral has been compromised where someone can get shocked. By definition again, then that case would no longer be neutral. Ask your question again describing your case with more details on the scenario where neutral can be compromised. The way you posed your question, it is an emphatic no and it would be extremely ignorant to say otherwise.

Yup. Absolutely been shocked by the neutral on a multiwire branch circuit. The circuit I was working on was off but neutral was apparently shared with another circuit that was not. I separated the neutrals and while twisting them back together, I got shocked through making contact on my sidecutters. Decent load on it too! Do not underestimate the neutral. If you're in a building that was wired when sharing neutrals was still up to code, you have to use your clamp meter to test for amperage & see if there is a load still passing through the neutral.

Human body is 300 ohms. 100 feet of 14 awg wire is 1/4 ohms. There is a calculation that will tell you what percentage would follow each path. Obviously 1/4 ohm is way smaller than 300 ohms so the wire will carry most of the load.

@professorg8383 Год назад
There are a variety of factors that go into how "badly" you get shocked. The number 1 factor is the voltage or potential. Everything else tends to be limiting factors to how well that potential allows current to flow. So the pathways the current takes can make a significant difference, You don't want current flowing through your heart or your brain. So trying to keep the pathways away from those two areas is in your best benefit. You can pass some fairly high currents in milliamps that hurt a lot and may even cause some burns or even some internal damage without being killed. But lesser currents that pass through the heart or the brain can lead to death. Ultimately, the resistance of the pathway, is the primary limiting factor. We have both internal and external resistance, (through the skin contact areas). There has been a lot of research through the years and one thing it tells us is that different individuals have different internal resistances. But in a given individual their resistance can vary through the day. Research suggests a few groupings across a sampling of individuals. The biggest grouping being around 80% who have very similar resistance and then two groups of about 5-10% that have considerably higher or lower resistance. So most people will have very similar levels of internal resistance, but there will also be some "exceptional" individuals on both ends of the spectrum. With this in mind, they developed current ranges and typical perception and effects of these current levels. Some things like perceivable levels in the few milliamp range. tingling, minor pain, extreme pain, muscle contraction. "let go" threshold, mild burns, etc, all the way up to typical lethal levels. Another key factor before we get to the internal resistance, which is quite low, we have skin/contact resistance. These end up being the pathway entry and exist points. This is generally higher resistance than internal resistance, but can vary widely. Dry, callused skin has fairly high resistance, soft, supple skin has lower resistance. Moisture can lower resistance dramatically. Larger contact areas make lower resistance. Pressure or compression, also makes for lower resistance. "leaning contact" is usually a larger area with some pressure. Leaning contact with moist damp skin and solid grips, will deliver some "strong" shocks. Women and children tend to be a bit more susceptible to higher current shocks. Body mass can play a role too. When grabbing something and getting currents above the so called "let go threshold", muscle contractions can tend to keep you in contact, being hard to pull free. This is generally thought to be around 30 milliamps. But depending on which muscles get activated, these can also act to push you away. Any jointed body parts have opposing muscles. So you can be drawn in or pushed back depending on which muscles get activated. Sometimes that can contribute to other injuries. So in the end, it generally gets down to the math, but the variables can differ greatly. Higher voltage will cause stronger shocks. The time length of a shock is usually pretty quick, but longer length shocks can be worse. When you get above around 300 volts or have sustained shock currents, flesh can began to breakdown. That will obviously be worse and can cause permanent damage. If you are on the low resistance side of the spectrum, you'll likely get worse shocks and may perceive small shocks that other don't. If you are on the high resistance end of the spectrum, you are a bit better off, but the variable factors can still make you vulnerable. You can get some strong shocks or be killed by 120 volts, but the potential is worse at 240 volts. If you are going to work with electricity, odds are that you will get shocked from time to time. The key is paying attention and using safe practices. Avoid working stuff live and don't do it because of laziness to shut something off. Depending on the type work you do, there may be times when there is little choice. It's just good practice to work things like they are live. even when you know they aren't.

I got shocked when I was unbundling some neutral wires, even though I had already checked that there were no live wires in the electrical box I was working in. Took me a bit of time to figure out why I got shocked. Turned out it was a neutral wire that was part of a multi-branch circuit and my panel didn't have a double breaker used for it. I appreciated your video on multi-branch circuits. I now treat neutrals with more respect.

I was digging up a steam line with excavator and a pipefitter jumped down into trench and cut pipe away from Building. When he touched both cut half's climbing out of wet trench he was electrocuted . 911 call. I saw him drop into trench and we tried to pull him out. He survived CPR used by a guy who was from Us Navy Medic. Turns out the steam water condensate pipe were bonded to ground neutral and when he cut pipe potential existed between both halves. His wet hands touching both sides almost killed him. In IBEW we were taught to test with back of left hand only .

Nailed it. I enjoyed the part about grid ceilings. I've been shocked the same way. Another reason I wear long sleeve shirts. Local story, lunchtime, foreman sticks around working lighting in a grid ceiling 277 hot. Something happened, lunch ended and workers reported a person's chest missing. Cooked. So unfortunate. They cooked in the ceiling because it wasn't what they were touching with their hands, it was the other thing their body was touching. Probably not related to the neutral. Great video. Been watching and all great content. I really appreciate that your content is CEU compliant. Amazing

@kenzo4Ever

No. In this case It is just a wire being the continuity of the hot wire (it's a hot wire then), standing there waiing to complete the circuit. If you touch that wire the circuit is then completed flowing through you to the ground (Completing the circuit) and you will be schocked Now If you carefully connect that wire to the common neutral bar of the house then it's ok, the current will flow now to your main house breaker then continue outside till the main transformer of the building area. There it's connected back to the transformer and also grounded and this is what is called neutral, it's all this path back "connection" to the main tranaformer and grounded there as well (for safety reasons) A broken neutral wire is just a wire, not a neutral. So be very carefull with this and with any wire 😅

My dad was dealing with a 1970’s bathroom with a 3 way switch. He turned off the breaker and then cut 2 wires at once and there was a flash and those wire cutters now have a big chunk out of them. The way the 3 way switch worked was they used another wire from a different circuit. That bathroom no longer has a 3 way switch.

An area with poor grounding can cause you to get “shocked” off the system neutral. Very common in rocky areas, guys will get poked off the system neutral or service drops

It's incorrect to say you must be touching two things .. If the neutral wire breaks from the earth connection that neutral becomes a live wire .. it's only a neutral when it is connected to the earth. So if it breaks from the earth it is no longer a neutral. .. it's a live wire so touching with one hand will be enough to get a shock .. the nearer the break is to the load the worst the shock.

Yes but I think what we mean is... can a neutral shock a person as opposed to a live positive; I wondered about that too...since the current goes back to the panel on the neutral I suppose it could shock a person but you would still have to be grounded? is that what youre saying? AND IS IT CORRECT TO SAY THAT THE SHOCK WOULDNT BE AS BAD AS A FEED WIRE BECAUSE THE CURRENT IS ALREADY SPENT PASSING THROUGH THE LOAD? does that make any sense?

So if I touch the black "Hot" wire as you did at 1:07 in the video and I'm standing barefoot on the ground or in a puddle of water I won't be shocked? Wouldn't the current try to pass through me to ground and back to the transformer?

When was a child, I grew up in a house that was originally built in the 1950's. It had a finished basement with two prong outlets. There was a lamp that we would turn on by pushing a switch on the lamp. I remember getting shocked by that lamp at random times and I didn't know why. Since I was a kid, I didn't understand what was going on. What was happening is that sometimes I was touching the metal lamp socket shell or cap while pushing the switch of the lamp. Sometimes I would do this with bare feet or with socks on. So I was completing the circuit with my feet even though the floor was tiled. I'm making this point because when we use the word "touch", people assume that means with your hands, they never consider that their feet can complete the circuit.

Bull**** You can ABSOLUTELY get shocked by touching JUST THE NEUTRAL. Last year I nearly fell off of a 20 foot scaffold after shocking myself on a 277 fire exit sign. I had to work on it live, so I was extremely careful. I capped the ground, capped the black and only had the neutral left bare. I used my linemen to twist the wire around (the other wires) to pull it out of the receptacle. Sure enough, I was preparing to cap the neutral, but the wire was all messed up, so I went to straighten it with my thumb and forefinger and BAMN. Got blasted HARD. My feet were on my wooden plank with my insulated boots, and both hands were above my head. One hand on my linemans holding the wire, ,(neutral wire) the other hand touched the neutral end.

Please explain to me how did i just not get hit by only touching the hot and nothin else oh i no my i was in Walmart shoes that were not non conductive so when you introduce your self as a ground you now are ground potential so there is no need for a neutral you'll be lit up like a drunk at a baby shower and please explain why you cant be hit by a loaded neutral to when the hot is off cause you do know that loaded neutrals (on a dead system ) can and will kill you please tell me how that dont work to and dont ever think you got to touch it for it to hurt or kill cause a.c voltage can ionize through the air to get to you for the least path of resistance but thats on hight voltage a.c and minimal separation is 3 foot without non conductive material clothing

Umm if one hand touches the live wire, on an open circuit, unless you are floating you don't need to have current jump out of your other hand. By standing, you are already grounded. So yes, touching the live wire on an open circuit will indeed shock, and.possibly kill you.

You can touch just a neutral and get shocked. It's just a wire it carries current. Remember you are working on a circuit that has an issue. 3 wires burned together. But its 10 feet down in the wall. You have a fresh pristine receptacle you grab the neutral and you get electrocuted and die. It's because down the line there was an issue. So never just assume it's all wired correctly. There is a reason you were called out to work on it. It's not brand new zero issue circuit. Especially on 277 volt commercial property's.

First, I find it somewhat criminal that you mention just in the last minute that you can quite easily make a full circuit by touching ground - or standing on it (from previous six minutes it would seem touching hot is perfectly safe (your drawing is also misleading in that way)). Brainstorming, when touching neutral (or "neutral") can be dangerous: (I live in a country with non polarized electrical sockets and 230VAC in them): - wrong colour of the wire (laziness or negligence) in the installation or even wrong labels - somebody somewhere turned aroud the plug that shouldn't be turned around or miswired it - interrupted or damaged neutral - can quite easily be at full hot potential, specially with higher powers - interrupted can easily mean someboy has managed to install a switch on it instead of hot - or a broken two pole switch, which turns off neutral, but not hot Let us not get in more exotic scenarios with multi phase systems and such. Generally, for me no wire in the installation is a neutral wire unless I test it to be.

I was rewiring a room one time. Though power was off initially. Then as I take a receptacle apart. I notice a 12/3 wire not the usual 12/2. Previous someone carried 2 hots from 2 breakers over on 1 cable. With seperate conductors. Then they split in a receptacle box. I had power off I though. Then I seen that. And rechecked breakers... I don't usually use noncontact "deathsticks" as they can be inaccurate but I now atleast use it as a 2nd or 3rd verification there is no power.

Just use one hand and you won’t get a shock, well in the crawl space was a copper water pipe, needless to say my ONE HAND was touching the live hot wire and that bare forearm squeezing between the copper pipes touched that and that was that. I shut the power off after that, and probably had no idea why that happened at the time. Your an excellent teacher btw. Thank you always

At 1:00 you are completely wrong. The hot wire in your example will shock you. The loop is through you, across the ground, up the ground rod to the source.

Re start the heart is number 1. If a heart is stopped by lightning or electric shock it is the rare instance that you might get the heart to restart without the paddles. Keep doing cpr until the ambulance arrives. Step 2 is look for burns and treat them. If there are burn marks really far apart, like a hand and a knee, their might be internal burns so call 911. If it is from your hand to your elbow still see a doctor but the damage is contained in that forearm.

You can be shocked by the neutral. You body creats the path to earth neutral and earth's are tapped together at the transformer. If you were to say take a lighting circuit. Turn every lamp on. And disconnect the neutral at the panel and you touch the neutral without touching the panel just standing on ground you can get some voltage and low current flow.

Alternating current can " capacitively couple" through an insulator. That is one of the functional characteristic of a capacitor. That's also why some LED lights will slightly glow in the dark -- the switch does a small amount of capacitive coupling. That said, the coupling can be negligibly small for practical purposes. Switches and circuit breakers are designed to have negligible capacitance.

Will you be shocked by a neutral if you touch two points in series on an un broken neutral? Your example seems to only show if those neutral wires were not connected. I suppose this is the same question if it was a phase a to a or b to b. There is no difference in potential so I am having difficulty understanding if current on can shock without a voltage difference between two points.
