NEC and Abandoned Conduit/Wire
Does NEC have any requirement for removing abandoned conduit, which does or does not have any wire in the conduit?
I'm ask because I'm expecting a debate to come up with an installation. The requirement is to replace an existing fire alarm system with a new system while the old system remains operational.
The client doesn't want to pay to remove the old conduit, wire, junction boxes etc. All he wants is to remove the old devices, control panel, and any exposed conduit, which might otherwise look ascetically displeasing. Wires would be rolled back above the ceiling into an old junction box and cover installed, but that's about it.
