Commercial wiring is most commonly installed in which of the following?

Commercial wiring is most commonly installed in metal raceways due to their strength, durability, and safety features. Metal raceways, such as conduit or cable management systems, provide excellent protection for the wiring inside, making them ideal for environments that may experience wear and tear, exposure to harsh conditions, or require grounding to prevent electrical hazards.

Additionally, metal raceways can help improve the overall aesthetics of commercial spaces by keeping wires organized and concealed, while also adhering to safety codes and regulations. They can mitigate risks of damage from physical impacts or environmental factors, which is a key consideration in commercial applications where equipment and foot traffic are prevalent.

Using metal raceways also allows for easier compliance with electrical codes, as they provide a robust system that can be grounded effectively, ensuring the safety of the electrical installation. These features make metal raceways the preferred choice in commercial wiring installations.
