As an electrician of 36 years I enjoy your videos very much as it reminds me of why we do what we do everyday without thought. It helps to refresh my memory thank you!

I have been doing this for 20+ years and "just knew" what do do and why. This explained it so much better than anyone has in my 20 year service.

Excellent! The details and explanations of US Home wiring in a concise 16 minute video are quite an achievement. The illustrations, animations and well paced narration essentially make this equivalent to a thick textbook and many hours of lectures in a classroom setting. Additional kudos for the on screen reference foot notes to to the Electric Code and the bonus GFCI explanation at the end! Thank you for these great videos.

This is absolutely the best presentation I have ever seen concerning this subject. I have been in the power business for over 40 years and my personal observation is that most people in this business, including myself, are hard pressed to really explain this adequately or have a true understanding of the "why" of this very important subject. Really great job. Thanks

We do not bond sub panels because a ground cannot be a current carrying conductor. If you were to lose the neutral in a sub panel, and it was bonded, everything would work through the ground. And as I just mentioned the ground can not be a current carrying conductor. Thank you.

Always wanted to understand why you don't bond ground and neutral in a sub panel. Thanks for the great content!

After years of asking why you don't bond neutral and ground anywhere outside the main panel and getting the response "because you just don't", I finally understand why. It's all about getting the breaker to trip when it needs to. I can also see why other countries requires GFCI breakers, as you're SOL if you lose service neutral in the majority of US homes. Thanks for making this extremely easy to understand!

I know it takes a great deal of effort and attention to detail to explain something in a simple way. The more you try to explain something simply, the more illustrations and flow you need to construct, in order to get across the information without leaving your audience feel like they've already lost you. You have done exactly that - put all your knowledge together without a ton of effort to transfer that to your audience in a short manner. In the field of electrical engineering, not a lot of channels or content creators do that, like we see in the field of computers and IT/programming. You are one of those few content creators who is also hands-on and detailed, and we see your level of effort and really, really appreciate you!

You have the best explanations on the platform. Please keep doing what you do!

This is the best explanation I have ever seen on the installation of sub panels and grounding and I have done electrical work for over 50 years.

Thank you for this, very informative. 22 ish years ago when I was a wee young apprentice plumber, I was cutting in an ice maker tee off the main and got whacked off my ladder. I found out latter that they 'lost the neutral'. I was so unsure about what actually happened, that for many years after, I would use jumper cables to jump any main cuts. To this day I keep an ncv wiggy in my tool bag for the occasional 'shocking shower valve'. Thank you again for this great presentation.

As an American, thank you very much, clearly British Engineering Mindset engineer, for explaining North American residential electricity. I appreciate it continuously as your accent's clear timbre narrates.

11:48 this is a ground fault and short circuit. Another possible ground fault is neutral to ground, which is not a short circuit and won't generally trip the overcurrent device. Just another reason why GFCI is important!

The Engineering Mindset drinking game: "Bus bar."

This has been explained to me 3-4 times and this is the first time I’ve understood it. Thank you!

Excellent video. Properly explained and I appreciate the correct terminology. I’m an electrician in Canada and we do it the same. The only difference where I am is a grounding electrode is not required for a sub panel if your bonding conductor is sized correctly. Of coarse you always have to check with your local municipality for amendments and technical interpretations to the national code. Every area is different due to things like climate and weather.

Transformers almost always connect to 2 of the 3 phases of primary, other than that this is one of the best and most accurately explained videos I've seen.

Nicely done. Many people don’t understand the ground/ neutral scenerios and you explained it very well.

This is I will say the best video I've seen explaining sub panel wiring and faults that could occur if miswired. Good job!
