Open Neutral

That was the best demonstration of an open neutral I've ever seen. Great idea using batteries to keep it safe!

Yup!

I wish this man was my teacher :(

You sir are a gentleman and a scholar

Wow that was amazing!

Thanks for the explanation

I don't understand why we use 120 VAC in North America when 240 VAC is available.

This is the REAL ElectricianU

You did not explain how a neutral works how does it send back only unbalanced current

Simple title, simple wiring, simple diagram, and simple explanation, all for a complex subject that so many people dont understand. Doesnt get much better than that!

So nice thanks sir

I already knew all this, but damn dude, that was one hell of a good explanation

Which Idiot connects his appliances in series Parallel/Series
Guess he is trying to kill people.

Didn't understand; stuck penis in electrical socket, severe burns.

Before this I had no interest in electricity, I was recommended this video after a Tom Scott video... but I was so into this.

This is so informative and in such plain English that I was able to follow along with no experience before this.

Thanks Dave!

damn sun, hope you are a teacher. real clear n' concise

Excellent!

Great demonstration. Question what happens when we have AC inductive or capacitive loads which separate/delay the voltage in relation to the current?

Gotta say, you saved my butt when I moved into a new house. Plugging my phone into an outlet in my shop caused the lights to dim, almost to the point of being dark inside, but not popping breakers, and turning on the outside light caused the lights to get brighter.

It was a helluva time trying to diagnose the issue until I randomly stumbled upon your videos.

Keep up the good work!

I first saw this video some months ago now, and liked it, but forgot all about it until yesterday, when the host of a radio show I was listening to was complaining about having computer issues. He said he burnt-out several computers in recent weeks to voltage issues, along with various light fixtures that get erratically dim, bright, or don't come on at all. That recalled this video instantly to mind! I'm thinking of calling into his next show to ask if he's still having problems, and to suggest he come and watch this very video. He may have an open or poor neutral, and it could be his service drop, so he might get lucky and the utility will fix it without him needing to spend for an electrician. He said he was going to try to fix the risk to his computer equipment by powering them instead through a UPS, but, depending on its design, it won't solve things, just possibly change where the damage hits.

If the incoming neutral breaks then the voltage on the neutral goes to the ground wire and from there it might seek alternative path out like the cable TV-connection. You also might get shocked from any grounded equipment.

Excellent!

Is there a difference when it’s 1/2 of 3 Phase 480VAC Industrial?

Absolutely awesome explanation and practical examples. Very didactic you should be a teacher. In fact you are. ;-)

Thumbs up & Subscribed 😁😁

Dum@SS

Very well explained

don't forget to like

Ok but how would u connect this circuit if u have one light and two battery in series? Wouldn’t one battery discharge faster then the other? How could you make it an even discharge

sometimes you come across explanations that just work you. its like calling customer service....if the first person cant help you, hang up and call back and eventually you get someone who goes the extra mile.

electricity confuses me. But I understand it a lot better now lol

Hello 600

That was the best lesson I’ve ever had on electrical troubleshooting.

Should be required review for any electrician in training...

In your demonstration you have the battery's connected in series on both sides of the neutral. So one side has "positive" voltage and the other "negative" , would this concept hold up with AC voltage, or with a circuit that needed a third branch?

nice!

ولا اروع🎉
شكرا جزيلا

Very very important concept.. appreciate it bro..

That's the best f'ing explanation I ever heard.

I was a Firefighter for 30+ years and saw a couple times how a missing or "dropped neutral" could burn up DC motors in refrigerators and washing machines and some times over load circuits. Usually from trees on power lines and downed wires as a result of a storm or strong wind event.

When I bought my home ( built in 1955) in 1997 No-one, not even the home inspector I paid noticed that the neutral had dropped off the utility pole. It was about a month later when I realized that all the lights in the house would flicker and dim a bit when the dishwasher changed cycles. I Called an electrician friend of mine and had the power company come out to re-connect the neutral while we were replacing the old glass fuse 100 Amp panel with a 200 Amp breaker box and brought everything up to code.

Great video! I had a neutral come off of a house I was renting many many years ago, burned up some motors and alarm clock.

This is simple electrical theory. Any electrician calling himself an being wowed this has never gone through schooling. Wait till the son of your non union contractor disconnects the neutral on a two pole breaker and fries all the brand new equipment he just bought. Trust Union electricians we have all gone through schooling.

AC LIVE 120v L1 NUTRAL GROUND LIVE 120v L2

Those Are Battery RETURED 1.5 X6 = 9V

I can appreciate the effort and the lesson here...
This brings me back to my military schooling, state lighting days, and wind turbine days...
Our lab for the state was set up using practical applications similar to yours, but also other configurations, depending on the areas across the state that we covered...
Once a person becomes familiar with a certain set of faults the troubleshooting just becomes parts changing, which is economically fine, but learning diminishes...js

Good visual representation of series, parallel, and series parallel diagrams and how current flows. Excellent job.

If I had they had teaching this good in public schools when I was growing up

It's also a BAD idea to share neutral wires under the same terminal lug in a panel. DON'T DO IT!

This is simple stuff of electrotechnics called as rule of power in sequentially circuit:

- In sequentially circuit less power consuming bulb will be more brighter bulb
(deduction - more powerfull bulb will be less bright)

There nothing common with power balance.
