Rigid Steel Conduit (RSC) is a type of steel conduit characterized by its thick walls, providing exceptional strength and protection. It is commonly used in heavy-duty electrical installations where there is a significant risk of physical damage or exposure to harsh environmental conditions.
Key Characteristics:
- Material: RSC is made from galvanized steel, which includes a zinc coating on both the interior and exterior surfaces to resist corrosion. Additional nonmetallic or supplementary coatings may be applied for extra protection.
- Sizes: Available in trade sizes ranging from 1/2 inch to 6 inches.
- Lengths: Typically supplied in standard lengths of 10 or 20 feet.
- Threading: RSC conduit is threaded at both ends. One end is equipped with a coupling, while the other end has a thread protector.
Applications and Standards:
- Durability: RSC is designed for environments requiring significant mechanical protection. It is ideal for areas exposed to moisture, chemicals, or other harsh conditions where electrical wiring needs robust shielding.
- Compliance: RSC adheres to Article 344 of the National Electrical Code (NEC), as well as UL 6 and ANSI C80.1 standards, ensuring it meets rigorous safety and performance criteria.
RSC conduit is a preferred option for industrial, commercial, and outdoor applications where the protection and longevity of electrical wiring are paramount.
