I was due to replace it with 350mcm (Not my choice...) in the existing conduit, but all hell broke loose when I told them I had to shut down the house side of the main, that contains 2 other elevators, 4 house lighting, and some massive air handlers on the roof. Other-wise, I'd have to get inside the 1600A busses to pull it in. That and one tenant will have to vacate for 2 days during the pull. (1 day out, the next in. If it comes out at all!) So right now its on hold.
But I am there tomorrow to trouble shoot poss harmonic +/or neutral problem in one of the tenant areas that I didn't do...... Go figure! So might get some PQM then.... Apparently the lower floor has turned into a discotech. Lights and computers flickering on occasion. Maybe this service call will lead me into the main. I'm dying to open it up.
Maybe I'll take the camera, I have some pipe work you guys and gals might find interesting.
