This is the best and clearest explanation with the simple and effective graphic demo for the concepts o grounding and bonding I have ever seen. Subcribed.

Why doesn’t this video have 100's of thousands of views? Why has the YouTube algorithm been hiding this channel for so long? They need to appoint a special counsel to investigate, promptly!

Thank you. I can't wait for part 2 so that I can finally complete my solar circuits. I have been searching for a simple explanation on how to connect a grounding cable to an off grid 48 volt system with an all in one inverter.

I am in Australia but i learned so much from this video. I have never come across this subject so well explained. Amazing and Thanks.

[stormmountain]

This will help everybody understand and clear up the questions.. very good. Video,

[ilyashick]

it is one of the best explanation with professional examples on electrical configuration

[raygibson]

Your knowledge and explanations are greatly appreciated.

[andrewborntrager]

Great video. Patiently awaiting part 2.

[Kanuka-Forest]

Excellent video, very clear and easy to follow. Thumbs up 👍

very good explain bro can you please make live video to show in live test anyhow very good way to make us easier to know love from pakistan.

Great explanation!

But I have a question which I'm really struggling to find an answer for. What happens in case you lose the incoming service neutral due to an accident or whatever, but your incoming service live wire is still intact? Since your neutral busbar is bonded to the grounding busbar at the main panel, won't that mean that everything connected to a grounding wire - all of your appliances' chassis - would be energized? Even an RCD wouldn't trip in case someone touches the live chassis because you have the same amount of current flowing through the live, through the load, through the neutral, through the grounding wire, and through the person to the ground. Is there a way to mitigate that or at least get warned if something like this ever happens? Of course, this is in case you don't have a grounding rod bonded to your grounding busbar. But even if you had, will its resistance be low enough to act as an emergency neutral?

I hope you don’t mind to answer my question. What’s the proper way to grounding a solar arrays on metal ground post? Thanks

[fokcuk]

Great series but have to rewatch it few times...
What happens if I have an unbonded stand alone inverter (earth has its own connector on the back of the metal case and neutral is not bonded to it), and somehow there is a short of live and earth. And I touch the case? Since it's not able to complete the circuit, I should not get hit?

¿Para un sistema off grid puedo tirar un cable ground desde el panel de breaker principal al panel de breaker off grid? ¿O deberia instalar un nuevo ground independiente especificamente para el sistema off grid?

Can you pls explain to your audience why to implement an RCD?
