Excellent refresher for us old salts!
-
Wow, this is dense material, but clear. I'd like to take an entire semester of lectures from these engineers. Thanks!
-
I'm going to have to watch this about 50 more times to really understand it LOL
-
Thank you for this video . It is the very first time that I have seen anyone explain about bonding a back up generator . I have searched many of times to no avail. I don’t see mention of it in the Generac installation manual either.

Great job Tom...!!! 👏
-
This is Beautiful! Thanks 👍
-
Excellent!
-
Very useful information thanks
-
Very well delivered material. Thanks.

This is outstanding material. I recently enjoyed a similar book, and it was truly impressive. "The Art of Meaningful Relationships in the 21st Century" by Leo Flint

great video I think very to the point instructions! Wondering if you can help me with a separately derived system question, I'm struggling with. 480v pad mount transformer 3 wires and ground ran to plant disconnect Plant disconnect to busway 3 conductors and case grounding to MCC MCC breaker 2 wire plus gnd wire feeds transformer primary 480v secondary single phase 240/120 panel. Question? is the ground wire from the MCC the only wire needed to ground this separately derived system or do you need some other electrode at transformer?

This is an awesome video
-
Great Video. Maybe you can add next time an example at fault condition why the code probihit something it would be a perfect explanation😊
-
Really good video
-
Great video.

3:03 I'm trying to qualify to be a home inspector. We typically only work with single phase electricity. Are you saying that you only see the ungrounded conductors in three phase? I'm confused
-
Wait a second. At 6:23, what is the purpose of putting a transfer switch for the neutral between the service and the generator if they are also both directly connected to the grounding system?

سلام سپاس تشکر درود و..هزاران 👍...جناب مهندس باشکوه ممنون همواره تندرست و شاد باشین

Great video, thank you so much. I think one point worth adding in regards to the EGC within a system. If my understanding is correct, it is connected to metal parts and enclosures that have potential to become energized in order to "trip" the over current protection device in the case of a fault.
-
Awesome video. So let's say I have an inverter (solar system) connected on the opposite side of the transfer switch similar to your diagram (just without a generator) . Is it recommended that I rather choose a 4 pole transfer switch instead of a 3 pole transfer switch? Secondly if my main incoming supply originally has n and earth bonded as your example above do I need to bond earth and neutral in my generator/ or inverter ?
