Learn Grounding Myths in this clip that is part 6 of a 7-part series called Electrical Fundamentals – Protection against electric shoc

I’ve wondered about some of these issues for over 40 years. Finally, I found these very simple (funny) explanations. Thanks!

Most modern day electrician have a poor understanding of electricity or at least how to explain it to the customer. So they offer parables and dumb down the understanding to the general public.

WOW !!! I am really surprised… You just change my mind about grounding. THANK YOU SO MUCH.

During my time in the telecom industry I was told all of these myths and more. Those “instructing” us were adamant about the “practices”. NONE of them had any idea what they were talking about but were passing this misinformation along over many years in a sort of “good faith”—all the while being blind and leading more of the blind down the same path. I imagine what faulty information was propagated by uneducated persons—who tend to “make something up” which seems to be right. In turn this misinformation is passed along, twisted even further and 50 years later bears no resemblance to fact. No wonder our mechanical trades so full of misinformation.

This applies to all trades—especially electricity—and welding—which is loaded with BS, myths, misconceptions, guesses and worse. When I learned to weld it was very difficult to find anyone who actually knew the physics of welding in even the slightest way.

This is the first sensible explanation I’ve ever seen concerning ground. I have heard all these myths before–and they are all wrong!!

Best explanation of grounding ever!

Great information.

The electrical grid transmits power over wires to our houses, and our Bryan Cockfield has covered it very well in his Electrical Grid Demystified series, but what part does the earth ground play? It’s commonly known to be used for safety, but did you know that in some cases it’s also used for power transmission?
