Have a 1800's home which HO installed sheetrock over plaster walls prior to electrical upgrades. Original wiring is bx umbrella circuits, with pull chain fixtures in all rooms. Our company ran nm to new swithes/new home runs/ interconnect smokes. Called for inspection prior to device install. Inspector wants all areas with new wiring to be exposed for inspection: Electrical permit specified old work on existing stucture with no service change, but inspector states that our wiring is new and must be exposed for inspection as such. My question is what is the the clasification between old and new install.
