However, when ever I ‘question’ the thinking process of any AHJ, I am given the act article/code that says ‘he/she is always right’. The name alone, AHJ, means I have to smile and say, “it’ll get done that way.”
P.S. back to the original photo, geezzz… I bet the freaking breaker has a photo/image embedded on the breaker to show HOW to properly double tap. The one I’m holding has one on the right side of the breaker. Boobs.
The problem I have as in inspector is I can only enforct the label instructions and there is nothing that says both wires on a QO have to be the same size or even the same material. The old ones just say “1-2 wires #8-#14 CU/AL”. I don’t have a new one with the instructions molded in the side but you can’t see that when they are installed anyway.
In my opinion, I don’t worry about codes or what the local AHJ says. If I believe there is a safety concern I will report it as such. A good example, locally the requirement for automatic closers for garage/house doors was dropped from the code. I still report this as a safety hazard.
Many manufactures rely on the fact if they don’t give instructions how to do ‘mixed’ sizes, then the one conductor per terminal screw applies. This is why I see many times in Square-D products, torque settings for pairs of the same size wires.
I didn’t mean to imply anything about the instructor, he was very knowledgeable and provided a lot of info. He wasn’t aware of the Sq D breakers. I did, as I encountered this on an inspection and talked to one of my electricians about it.
Ahh…no problem as I was saying not to discredit the instructor but to imply things are always changing and staying current with changes is always a weakness for those who are not in the actual field on a regular basis.
