Emt for ground

Sure was it such an outlandish question? We hear about "I want it done my way" rules here all of the time without any basis. I would disagree with the bold. Just my 2 cents.

Thanks for providing the info.

I also strongly disagree with the bold. Additionally, wonder if they had any basis or statistics on EMT being insufficient ground fault current path? Doubt it.

I have no problem with them requiring something above and beyond the NEC but the bold part is simply not true.

I agree, but it is also simply not true that adding a wire EGC makes a safer install

Not an outlandish question at all. I was being silly more than anything.

On that same job I mentioned, the inspector made me pull EGCs on even the rigid pipes. because they were connected to the EMT and boxes.

This is the “story” I was told.

There was an electrocution of a kid, in the 70’s I think, in Phoenix. EMT was used as the grounding method. The pipe had become separated and was energized so when the kid grabbed on to the pipe it killed them. After that, it was amended out of the code.

I heard another story that after that, another kid was killed. Turned out it was a poor wire nut connection on a wire EGC, ground wire became separated.
