((D) Removal. Temporary wiring shall be removed immediately upon completion of construction or purpose for which the wiring was installed.
IMO You are the AHJ and what your asking him to do is covered under the NEC as Dennis stated and I looked it up for myself. He needs to take the temp wiring out case closed. Now is he asking for a code refc. do your not carry a code book in your truck? Just asking not trying to be a smart alecI am inspecting a job where the general wants to leave the romex wiring for the temporary lighting in the ceiling overhead and just kill it. I told him to make sure all of it is removed, but could not give him a code reference. Any ideas?
