Code is one thing. At the end of the code it states "Or as local authority dictates" Which translates to what ever the local inspector (aka, self proclaimed god) believes to be the correct interpretation of the code.
A few years ago at the Ford World Head Quarters building in Dearborn Michigan, "The Glass House", an older building, there were multiple hard lines going through the elevator equipment room for years. No equipment in the room, just passing through. The inspector came in and said "move them out". For one reason or another that got delayed. He came back, said "Remove them immediately or I will be back with an ax." They got moved immediately........ So moral of the story, you run the risk of liability. So just don't do it. I know we all want the shortest run but those are the rules. Run it outside the room to another area or you may pay. Heck, it might be you in the elevator leaving when you test the repeater on the way down, one last time and you drop like lead 39 floors to go SPLAT. Now that would be ironic... 73 Shanon
