title: Raceways and Conduit
…2 unchanged lines
description: >
When to use: Conduit, tubing, and raceway systems that enclose and protect electrical power, lighting, and signaling conductors in commercial, institutional, and industrial buildings — including rigid metal conduit, intermediate metal conduit, electrical metallic tubing, flexible conduits, rigid PVC conduit, surface raceways, metal and nonmetallic wireways, and conduit fittings, boxes, and supports. Covers indoor and outdoor, exposed and concealed, wet and dry, and direct-burial raceway routing for branch circuits and feeders rated 1000V and below.
− Not intended for: Underground concrete-encased duct banks and manhole/handhole structures (see [[sync/underground-ductbank]]), busway and busduct systems (see [[sync/busway]] and, above 600 V, [[sync/medium-voltage-bus-duct]]), cable tray systems used as the primary support method for cable wiring (see [[sync/cable-tray]]), the conductors and cables installed within raceways (see [[sync/conductors-and-cables]]), raceways for fire alarm and limited-energy systems where governed by separate project standards, and hazardous (classified) locations (see [[sync/electrical-hazardous-locations]]).
