Got into the main electrical room today and my first visit I see things of note.
This is a large manufacturing plant! The plant is generally all run with aluminum cable tray. It seems everything is in a cable tray, here the first puzzling question!
Why are all the gear, mcc, other distribution panels in this main Electrical room all stubbed up to above ten feet in galvanized pipe, like a smoke stack! They had either plastic bushing on the pipe end and the cable is TC running up to a tray. Or in the case of a few pieces of equipment it was galvanized and it changed over to EMT. The odd thing is that other house services on block walls below ten foot were only EMT, being either light switches or receptacles or even the pull station.
I don?t understand the fixing of the different styles of running conduits, if it?s an electrical room to some classification than why not everything up to ten feet be required to be galvanized?
Thoughts? Thanks in advance!
