How many electrical conduit types do you know?

An electrical conduit is a tube in which electrical wires are housed for a variety of building or structural applications. And there are different types of electrical conduit to protect wires as well as any individuals who may come into close proximity to the wires.


Electrical Metallic Tubing

Electrical metallic tubing (EMT) is made from coated steel or aluminum and is a more economical and thinner-walled option than other conduit. This conduit type doesn't offer the same protection as rigid metal conduit but is lighter and can be paired with conduit fittings, eliminating the need for threading. EMT can also be bent to shape using a special tool to fit around obstructions or follow the shape of the installation.


Intermediate Metal Conduit

Intermediate metal conduit (IMC) is a type of a rigid conduit rated for outdoor exposure and is intended for protecting insulated electrical cables and conductors. It offers much of the same protection of rigid metal conduit but is a more economical option for projects where cost is an issue.


Rigid Metal Conduit

Rigid metal conduit (RMC) has a thick wall and is constructed of either aluminum or galvanized steel. This variety is one of the most heavy-duty types of conduit used in many industrial applications. Rigid metal is one of the more costly options but offers additional strength.


Galvanized Rigid Conduit

Galvanized rigid conduit (GRC) has the thickest walls of all electrical conduit and is the heaviest. GRC is regarded by electricians for its superior corrosion resistance, and it protects wiring from electromagnetic interference (EMI). GRC can be used in outdoor or indoor applications and can be exposed, concealed and buried.
