Thank you! So glad I came across your channel! Your explanations are very clear and straightforward.

Zack, the way you explain things is clear, concise, and easy to understand. Thank you for sharing your knowledge with us.

Very informative well explain, it means a dangerous thing once the neutral conductor is removed in a wye transformer config 4 wire distribution system. Some loads will be like a firecrackers since they will be operating at higher voltages beyond their ratings, while other loads from other phases will experience low voltage and will experience heating causing damage eventually if not addressed immediately by the utility company. It is a floating neutral. It is like a boat that is not achored when the owner left it, and to his/her surprised the boat is gone taken away by the wave.

Thank you Senior Pablo!

I once got shocked doing a plumbing repair that had a ground cable going to it from Earth. I was standing in water and soldering the two pipes together. What a pleasant experience when I grabbed both pipes simultaneously.

I love this channel, the whole drawing thing is a genius idea and works great for any kind of explaining

Excellent! Like how you formatted the video! Easy to understand. Larry

So what I wanted to know during this whole great video(and it is good) was what the voltage is going to be at the broken neutral to ground or in your drawing at the purple x . This is so important and I cannot beleive you skipped this part about "broken neutrals". No offense , but such a good video should include the shock hazzard associated there. In your circuit the V-drop for both resistors is 115v for the higher Z and 92v for the lower Z so what is the voltage at X (broken neutral to ground) Jim.

I please with your content. Thank you very much. Please keep doing this, Soon you will popular on this platform

If the ground is hooked up to the neutral point, does that mean that current goes to ground when it's energized

I was in a factory when they lost Neutral connection, I had a laptop charger plugged in the Charger literally blew up, Lap top, survived frightened the living day lights out of me. This was in the UK where our single phase voltage is nominal 220v.

Excellent explanation

Thanks alot for your tutorials and it's very useful for me and I've got 309A license

so the neutral is basically like a wastegate for unbalanced voltage?

very informative video, congratulation

Hi Zac, Thanks for this great video and informative explanation. Would you please advise if neutral wire breaks on three phase power supply, within a DB with RCD is installed in, would that RCD trip off and cut the power off in case of loss of neutral wire. Thank you.

In your example you are not considering the L3. So, the two loads are not in series, as part of the current is flowing to the 3rd phase.

I wish I’d have had a chance to watch your videos back when I was struggling in technical college, my grades would have been much improved. Great explanation, really clear and brilliantly presented. Thank you!

Indicated open neutral. The less LOAD (8A of current) will continue to function. HOWEVER do not touch the open neutral (line side) as indicated. Kirchhoff’s voltage rule for series circuits. Believe this is correct, comment please.

You said it becomes a series circuit but what about the third load that isn't visible on the screen?

Will it become a phase to phase short circuit condition when neutral breaks ?

Awesome video

What about when the neutral isn’t broken but becomes a higher impedance. In Australia we have the earth tied to neutral so if the neutral break current will flow back to the source via earth. Earth stakes can be very high impedance.

Super sir

thanks for the education, do you have any recommendations for an auto transformer to run my 2hp well pump with 4000 watt inverter? i have 800 watts of solar panels and will have 8 186 ah 6 volt golf cart batteries

So wait if i have only ground and live without neutral. Device will not work, but can be damaged? And there is not some device in electrical system what can stop damage?

He writes faster backwards faster than I can forward. Impressive.

Surely if the is a third phase that becomes a parallel path

Can you explain it with the 3 phases and 3 unbalanced impedances?, because of the current have 2 paths on the joint, so how i calculate the current on the differents loads when the total load is unbalanced i cant use root3, So i can calculate each (Z) voltage for a given unbalanced load with no neutral

You are ignoreing the main earth
