Stripping the outer non-metallic sheathed jacket off Romex cable to run the individual insulated internal wires inside electrical conduit is strictly prohibited by the National Electrical Code (NEC) and poses a severe safety hazard. Romex inner conductors lack the individual UL-listed THHN/THWN outer nylon coating and moisture-resistant ratings required for standalone conduit installations. Stripping the protective jacket exposes the wires to abrasion, damages insulation integrity, and invalidates code compliance, risking electrical shorts.
