This video presentation was a good back up course for the “how to conduct electrical inspection” course. However it would have been good if they included an inspection of a fuse box type service panel as I’m sure they are encountered often with many violations and hazards?
Our InspectorOutlet provides a lot of our inspection checklists as free downloads. You can also get PDF textbooks, printed textbooks, and a ton of inspection tools.
I cannot find a supplemental grounding electrode at my home. There is a bond at the copper water pipe but cannot see anything else. My house was built in 1954 in Canada. It is a block foundation with a finished basement and the side where the service entrance is located is my concrete driveway. Was it always required to have the grounding electrode? What level of concern would this be when writing up a report?
In your video you state that transformers are not allowed inside panels
Article 408.38 of the NEC states that panel boards shall be mounted inside cabinets. Article 312, cabinets & cut-out boxes. Cabinets have a yellow and red tag which states the cabinet is UL listed. Article 312.11(A) states that ample space between metal parts of devices and apparatus mounted with in them, some restrictions apply. Are not transformers, relays etc, consider an apparatus or device which then according to this article would allow them to be installed in a load center?
Thanks

Good question. I believe the best practice is to not mount it within the panel, and that is what we teach our members. I believe if a doorbell transformer were to be used in the breaker panel, it would have to be listed for such use and also listed on the panel label by the manufacturer.
