A little off topic but do many of you guys come across elevators in residential? Getting ready to quote on a job with one.

Maybe 1 every 2 or 3 years. Resi elevators don't normally have a pit. The pump or motor sits on the floor of a closet near the elevator, or in the attic. There isn't much to a resi elevator. The last one I did just plugged in. I should say that I don't install them... the elevator people did that. I just put the receptacle there for them.

These things are getting cheaper and cheaper all the time, so I suspect that they will get more popular as the population ages, particularly in a remodel application. I know I've seen some in the 8-10K range. People spend more than that often times on their stone counter tops.
 
The last elevator I did (residential) I provided a 240v 30 amp circuit to a disconect, and the elevator guys took care of the rest.

I did wire the equipment room with light and GFCI receptacle, and provide a telephone line.

Yup - Almost the same requirements for my last install except the elevator guys asked me to install a 3 phase 30A disco so they could run one one extra conductor (battery power?) thru the disco for their hydraulics - They also required a second disconnect in the equip. room for the elevator lighting. The equipment room and the pit (yes this resi install has a pit) needed GFI power. The pit required a protected light with switch.

I dont know how an elevator could be installed without a pit... Unless you dont mind stepping up into it at the basement level. (Kinda defeats the purpose) ;)
 
The elevators I've done all required 3phase disconnect, 30a 240v supply, 15a/120 volt circuit for the elevator light and a telephone line, Elevator company did the rest.

Two posts that lift a plate up and down.

I see them with depressions not pits - about 6 -8" so you can avoid stepping up in the basement.

I've only been involved with 2 or 3 residential elevators, so they could be the exception, not the rule.

Well, yeah. Even the one I talked about that had two posts that lifted up and down a plate had a little indent in the floor maybe 3" deep for some understructure of the plate to go down into.

These residential elevators, in my experience, are just hopped up dumbwaiters, and not so much like the Otis you're used to seeing in commercial buildings. I suppose there are folks who have genuine real elevators in their houses, but I think those are special cases.
 
I don't know ! :)

I don't know ! :)

Is EMT allowed in elevator pit

Were getting ready to do the install of conduit/service to the elevator.
Our specifications call for anything under 48" AFF is to be in rigid. First floor only, this is a pit elevator.

In talking with the elevator guys I conveyed that aspect of our work, and I think it caught them off guard, and caused a raised eye bowel.

They assured me they'd check, where a long week off from the a work!Other elevators on campus have been done in EMT they assured me, I assured them that the Low Voltage guys had also run Emt under 48".

I conveyed the conversation to my boss, this was before Christmas week, I guess I should rehash that conversation.

Here in western Montana i ran into a lot of residential elevators. It's because most of the houses that are built here are a minimum of 4,000 square foot houses and not cheaper than $1,000,000.These houses aren't cheap and have nice elevators in them. They aren't receptacle plug in type. They have concrete base under them and they stay there permanently.

FWIW

I think we were thinking of two different things. I thought the recessed pits only function would be for the level "step in" transition at the basement and nothing to do with the lifting apparatus. I'm showing my lack of experience with the larger "Otis" brands etc. -

This residential unit has a 14" deep poured concrete pit (new construction) and uses a hydraulic ram mounted on the right side of the elevator shaft. Two continuous rails mounted either side of the ram (mounted on the same wall), guide the car.

I stopped into said job yesterday to double check the elevator guys conduit runs. They did use regular ol' EMT below the 48" mark to feed up to about 14' where they exited the conduit with the car power cord. It was supported with a Kellems grip where it exited the pipe. The cable was then fashioned into a standard hanging "J" loop that connected it to the side of the car.
