How do Raceways protect electrical wiring in buildings based on NEC (National Electrical Code)?
The building power distribution system distributes electrical power to the point of use and then throughout a building.
Power distribution uses a wide range of
- Circuit breakers and
- Switchgears .
The majority of electrical distribution to industrial & commercial loads is accomplished via wires and cables housed within raceways.
These raceways carry the conductors that provide power to different parts of equipment throughout a building.
Copper conductors are commonly utilized for interior power distribution. Raceways can be massive metal ducts or stiff metal conduits.
These raceways offer a compact and effective way to route cables, wires, and other components across a large building or industrial complex.
NEC Requirements for the Raceways
- Article 300: General requirements for wiring methods & materials.
- Article 310: Conductor sizing & ampacity.
- Article 344-362: Guidelines for different types of conduits & raceways.
- Article 392: Cable tray systems & installation requirements.
