At 4:05, the picture on the right does not accurately represent the question purpose. Drywall is not a combustible material and therefor does not prohibit the box to be recessed up to 1/4". The image on the right shows a recessed box but no reference is provided to gauge the setback depth. The image is used in the context of combustible wall surfaces.
On the example question asked… what minimum grounding electrode conductor size for Aluminum or cc-aluminum for #2awg. You said the answer is 4… but shouldn’t it be 6? Because 2 is smaller than 1/0 Can you explain the answer?

Agreed
2/0 is not the same as 2awg...answer is 6awg.
hello guys, any link as to how to a get a well detail video for mechanical inspectors?
Do they have a video for the E2 test

Depends it’s 4 for main water bonding for most AHJ
