Conduit can be ___ and provides a pathway for the limited energy wires to run through walls and ceilings and from floor to floor.

• A. metallic
• B. nonmetallic
• C. metallic or nonmetallic
• D. both metallic and nonmetallic

Answer: (C)

Conduit serves as a protective raceway for conductors and can be made from either metal or nonmetallic materials. It provides a path for limited-energy wiring to run through walls and ceilings and between floors, while offering mechanical protection and, in some cases, grounding or corrosion resistance. Metals like steel or aluminum offer rugged protection and, in many systems, a grounding path. Nonmetallic options such as PVC provide corrosion resistance and easier installation in wet or harsh environments. Because either type can be used depending on the situation, the best completion is that conduit can be metallic or nonmetallic.
