Elevator Shunt Trip breaker locations

[Hoosier_Sparky]

Question: What determines where the shunt trip breaker is to be located?

Background: We have an elevator company that shall remain un-named requiring us to move the shunt trip breaker (physical location of said breaker) from the gear room of a fire department to the elevator equipment room in the same building. This is a new build, new structure, not a renovation of any kind. The engineered drawings call for the shunt trip to be installed in the gear room. the installation is typical Heat detector = notification to elevator controller = trip. Looking through every forum I can think of, i can't find a clear "in this instance shunt trip breaker moves to elevator equipment room" kind of answer. As a matter of fact, there are more and more municipalities and AHJ's that want the shunt trip out of that room because water running into the breaker "could" cause voltage to transfer past the open/tripped breaker possibly making the elevator function erratically.

Any guidance or reference please?????

I've never heard of this being a requirement. The one time I had to go out on a test for the shunt trip breaker, the breaker was, in fact, mounted in the service room. Tell the Nameless Ones to provide you with the relevant code reference or go...well, you know.

Since this is an engineered design, I'd bring it up to the engineer and let them know the additional charge of an extra if I had to move it to some place other than where I had quoted it to go.

If I have already installed it, I'd bring up what the elevator guys were asking to the engineer and let them know I would charge an extra if I had to move it.

Either way, it's not your problem to deal with.

In Florida, the elevator inspectors are the worst for making up rules on the fly. They have more clout than AHCA and that is a lot. You just end up doing what they demand and moving on. On my current job they required a smoke detector in the top of the elevator shaft when there was no sprinkler. NFPA 72 states it SHALL not have one. It has one.
