Final answer:
The National Electrical Code does not allow rigid PVC conduit to contain conductors.
Step-by-step explanation:
The correct answer is c. Contain conductors. The National Electrical Code (NEC) prohibits rigid PVC conduit from containing conductors because it is not suitable for direct contact with electrical conductors. Instead, the rigid PVC conduit is used to protect and route electrical wiring within walls and ceilings, providing a secure and durable pathway for the wires.
For example, in residential and commercial buildings, rigid PVC conduit is commonly used to protect electrical wiring running through walls and ceilings. It is rigid enough to maintain the shape of the conduit and is fire-resistant, making it a safe choice for indoor electrical installations.
In contrast, the NEC allows flexible PVC conduit to contain conductors, as it is designed to be more pliable and can bend and flex to accommodate wiring installations that require movement or flexibility.
