===Conduit and cable protection===
The NEC requires that conductors of a circuit must be inside a raceway, cable, trench, cord, or cable tray. Additional protection such as NM cable inside raceway is needed if the installation method is subjected to physical damage as determined by the authority having jurisdiction.

The NEC sets three general requirements that PVC conduit must meet to ensure safe electrical installations. These requirements include:<ref>{{Cite web |last=Ledes |first=tube |title=Understanding the NEC PVC Conduit Requirements |url=https://www.ledestube.com/understanding-the-nec-pvc-conduit-requirements/ |url-status=live |website=Ledes}}</ref>

'''1.Compliance with UL Standards:''' PVC conduit used in electrical installations must comply with the UL (Underwriters Laboratories) standards specifically designed for PVC conduit. This ensures that the conduit meets the necessary safety and performance criteria.

'''2.Environmental Suitability:''' PVC conduit must be suitable for the environment in which it will be installed. Different types of PVC conduit are available for indoor, outdoor, wet, or corrosive environments. Choosing the appropriate type ensures the longevity and reliability of the conduit system.

'''3.Marking and Identification:''' PVC conduit must bear proper markings for identification, including the manufacturer’s name or trademark, conduit size, and applicable electrical standard. These markings help in identifying the conduit and verifying its compliance with the required standards.
