Elevator EGC

[AC\DC]

It was a compliant install in the 60s when it was put in. I’m just wondering I’ll wait to see what my Electrical Inspector says cause the elevator inspectors really shouldn’t have any saying my disconnect he should just have from the disconnect on.

That fitting does look like someone cut a coupling in half, installed an indenter type fitting for the EMT. I have no idea what is holding it to the enclosure. Looks like they tried to braze it together.

I found the fitting it’s an old Reiko 1970s fitting. It’s an EMT fitting that goes into a coupling and they threaded the coupling on the TA and then they used a chase nipple to thread into the coupling.

We pull a insulated EGC here I don't have my code book handy but I what thought is there is some general wording in 620 that basically applies to all 'conductors' having to have certain types of insulation like THHN? Since an EGC is a conductor we use an insulated EGC. There are a few other gotchas when doing elevator / escalator work like the termination of the fine stranded cables etc.

ya but emt can serve as a egc and is better than a wire for clearing a fault


You can either have a loose lug and then your EGC is not effective or a loose set screw and your EGC is not effective either way. It’s all up to craftsmanship so this whole conduit or wire Debt people have is pointless.

I just wanna have it streamline, get passed no one dies and I get paid

Just talked to another inspector he’s not in that jurisdiction but he said Mike if it was a kosher at one time the head Electrical Inspector says it’s existing there’s no need to address it so I should be good

An EGC is a conductor and when 620 applies it has rules for all conductors , I am on different code cycle than you (2017) but I doubt its changed much;

620.11 (D) Insulation. All conductors shall have an insulation voltage
rating ...

Thats just been my understanding, I have always pulled a green wire for elevator work.

Well, Electrical Inspector passed it. He says the chief Electrical Inspector says as long as it passed, doesn’t matter how old it was at the time of install it’s compliant still as long as we don’t change it and since I didn’t change the piping system, it’s good. also, he said the elevator inspector is Justin in charge from his controller on, he can’t dictate what we do in front of that

On another note unrelated to that since I got more informed, I don’t swim in public pools because the amount of stupidity I see and that danger, and now after dealing with an elevator and an elevator electrician mechanic I almost don’t wanna ride in an elevators anymore.
