How many types of electrical conduit are there?
7 Types of Electrical Conduit. 1 Rigid Metal Conduit—RMC and IMC. Rigid metal conduit, or RMC, is heavy-duty galvanized steel tubing that is installed with threaded fittings. It is 2 Electrical Metallic Tubing—EMT. 3 Electrical Non-Metallic Tubing—ENT. 4 Flexible Metal Conduit—FMC and LFMC. 5 Rigid PVC Conduit.
What type of Cond conduit is used for residential wiring?
Conduit used for residential wiring includes several types of metal and plastic materials designed for different applications. Here are the most common types: EMT: Electrical metallic conduit is rigid, thin-walled metal conduit typically made of galvanized steel.
What is 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.
What is electrical conduit made of?
A conduit can be made of metal or plastic and may be rigid or flexible. All conduit is installed with compatible fittings (couplings, elbows, connectors) and electrical boxes, usually made of the same or similar material. Conduit must be installed in accordance with the National Electrical Code (NEC) and all applicable local code rules.
What is 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.
What is electrical conduit?
Ejla / Getty Images. Electrical conduit is metal or plastic pipe through which electrical wires are run. Either rigid or flexible, conduit protects the wires and is used in exposed locations, such as along the exterior surface of a wall.
What is EMT conduit made of?
EMT: Electrical metallic conduit is rigid, thin-walled metal conduit typically made of galvanized steel. Because it is thin-walled and lightweight, it is easy to bend with a special tool called a conduit bender, and it cannot be threaded like a heavier conduit.
