What color is plastic conduit rated for electrical use?

Plastic conduit that is rated for electrical use is typically gray in color. This color is standardized because it denotes that the conduit is suitable for electrical installations and indicates the type of materials used in its manufacturing. The gray color helps differentiate it from other types of conduit, such as white, which is usually associated with non-electrical or specific plumbing applications, and black, which is generally used for high-density applications like underground installations.

In addition to its color, the properties of gray plastic conduit—such as its resistance to moisture and corrosion—are important for maintaining safety and durability in electrical work. These conduits are often used for rigid applications and can protect electrical wiring in various environments, making it essential for installers to recognize and utilize the correct conduit for safety and compliance with electrical codes.
