What does the acronym "GRC" refer to in types of conduits?

The acronym "GRC" refers to "Galvanized Rigid Conduit." This type of conduit is a durable and widely used electrical raceway system made of steel that is coated with zinc to resist corrosion. The galvanization provides an extra layer of protection against moisture and environmental factors, making it suitable for both indoor and outdoor applications. Galvanized rigid conduit is known for its strength, reliability, and ability to protect electrical wiring from physical damage and electromagnetic interference.

Understanding the construction and application of galvanized rigid conduit is essential for ensuring compliance with safety standards in electrical installations. It is commonly utilized in industrial settings, commercial buildings, and other environments where robust conduit solutions are necessary.
