Grounding and Bonding

This is a brief walk through of a simple grounding and bonding system, and what happens with the flow of current in normal operation, and in a ground fault condition. There are no Code Rule references, however please be advised terminologies follow the 2015 Canadian Electrical Code.
Please be advised that in the last scenario, where there is only the path through ground, depending upon your location, there may not be sufficiently low impedance to trip the main overcurrent. Always ensure proper continuity of all grounding and bonding systems with the help of a licensed electrician.

Feel like buying Chris a coffee? Think of it as SchulerRuler fueler!

Great! Thank you! Today I tried to explain the reasoning for grounding and bonding to an employee, and your illustration is WAY more efficient than anything I could come up with.

Thank you so so so much!!! You are an awesome instructor. I’ve been researching and talking to knowledgeable people about this particular subject without any understanding. You definitely have made it easy to understand. Thanks again.

Wow what a great explanation of the different ways that the N.E.C. establishes rules and regulations to protect the typical person. Keep up the good work. Remember to take out a permit from you local agency if you do any type of electrical work or upgrades in your home and only use qualified electricians to make the changes otherwise if there is a fire and it is traced to defective electrical work your home insurance may not cover the damages.

Excellent video. I'd like to add that scenario #2 also takes place simultaneously in scenario #1 but imagine it's not shown for clarity. Once current hits the ground bar, it's going to flow in the neutral and ground return path and ultimately end up at the source. These paths run parallel from the bus bar to the meter and more current will flow in neutral path since it's likely made of copper vs the aluminum or steel raceway

This video really helped me understand how it all worked, this is good to know because if you mess up anything it will still be able to trip the breaker.

FINALLY! AFTER 3 YEARS OF ELNC ENGINEERING AND 100 VIDEOS ON THE SUBJECT!!! SOMEONE WHO UNDERSTANDS LANGUAGE AND KNOWS WHAT'S GOING ON WITH GROUNDING!!!

[maxwellkellogg]

Great video! I got my degree in Computer engineering, and feel very comfortable with electrical theory. But these kind of explanations, involving EMT, and power coming in from your power pole outside, are not often taught in school. They are the great to bring Electrical systems into reality.

Thanks!

[jrutube]

Very well done explanation that simplifies the NEC Article 250 overall concept. Thanks !

[sunshine]

Thank you for your clear animated presentation that makes thing very clear and set up different real scenarios. Great job!

[jenko]

Great video, so many people think the grounding electrode will clear a fault or remove shock potential and it won’t and your video clearly shows how you clear a fault or remove shock potential.

[ChevyCeeLo]

Very informative, you answered my question in depth. Thanks! 👍

[Ducktruckful]

what a great video! the best explanation I have every seen.all the years I have been around electric systems There has never been information this clear . thank

[chrisschmidt]

Super and easy to understand presentation. not those confusing Talkarounds right to the point
Thanks verry much

New meter sockets have a separate lug for ground now and the panel bond screw would be green.

[mohamedalsaidi]

Great video, Thanks for explaining it step by step. The animation is awesome, it made it so easy to understand.

[kylelikeskjvbible]

Your videos are amazing, its so easy to follow. You really helped me when I did Electrical Theory 1 last semester with the 3 wire Edison Video. Our books and instructors are good, but you explain a 1 hour concept in like 10 minutes which really helps when theres something we need help on.

[apackwestbound]

Thank you for making this video, it is well done and clear.

[nogarats]

Good and simple explanation. Got the guys into a good discussion about old mentality/perception thinking that the current goes thru ground and back to panel ! Like you videos, kind of like Mike ones. but it's about CEC witch is more for me :)

[kaaaah]

This was a great way to learn power panel's jigsaw puzzle particularly grounding, bonding and neutral. Hope hit 5M in your life. Generations will come and learn from this wow video.

I think one of the biggest problems understanding this is understanding that when talking about ground all grounds are not created equal. You have your grounding rod or earth ground. You have your metal body of your car or the chassis ground. You have your ground on your outlet, the fault current return ground. You have your shield on your guitar cable and when you get a buzzing sound they say they have a bad or broken ground. When you weld and you can't strike an arc you check the welding ground cable to the work piece. I think you've done a great job explaining ground in this application.
