Hi, I do mostly residential and have never wired a car lift before. I read the directions for the electrical and it states that I could use a twist lock for my disconnect. I would like to know from someone who has wired these what is the usual wiring method you use and also what code articles apply to this type of installation. The client would also like receptacles installed on the side of the lift is this code compliant? Thanks for any or all info on this subject.
 
I've put in a good many 2-post lifts over the last few years. I put a sidearm disconnect on the wall, normally. I feed the lift with EMT if I'm coming from overhead. Sometimes solid EMT the whole way, and sometimes the last few feet in Greenfield. I'm not a big fan of rubber cord for something that's gonna be pretty permanent, even if all the lift's limit switches and such are factory wired with rubber cord.

I don't see any special issues with receptacles on the lift posts, but there's not much real estate on those posts. Best of luck finding a place. Just keep in mind the hazardous zones in repair garages, and don't mount a receptacle that low. They normally like them around 48" in a repair garage for convenience sake anyhow.
 
They just built a new service faucility for a dealership here and put in about 20 lifts. The did drop SO cord from the ceiling, and I know I questioned it and they had a reason for doing it, but for the life of me I can't remember what the reason was. They mounted the disconnects on the lifts and I thought they were to high until he pulled 404.8(A)(1) Ex. 2 out of his hat. No outlets on the lifts, since each lift had a work bench next to it. The problem with the outlets, along with the ones Marc stated might be that the lifts are 3 phase and you will have to bring power from two different sources.
