- 5.4: Conduit, Boxes, and Wiring
- Raceways are defined as enclosed channels of metal or nonmetallic material designed expressly for holding wires or cables. Branch-circuit installation using a raceway (conduit) wiring method is seldom used in residential wiring. However, some areas of the country require that all wiring in a house be installed in a raceway wiring method. Raceways should be installed as a complete system and be securely fastened in place and supported by an approved retainer.
