What is conduit used for?
Special connectors are used to secure conduits to boxes and to join lengths of conduits together to form long straight runs or bends. The boxes, connectors, and conduits form a wire enclosure system called a raceway. A raceway is an enclosed conduit that forms a physical pathway for the electrical wiring to follow. In this way, the metal raceway acts in place of the grounding wire that is found in non-metallic cable. (This is also the main reason why only metal boxes may be used with metal conduit.)

Electrical Conduit
An electrical conduit is a tube in which electrical wires are housed for a variety of building or structural applications. Conduit protects wires as well as any individuals who may come into close proximity to the wires.
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.
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.
PVC Conduit
Polyvinyl chloride (PVC) conduit is the most popular type of non-metallic conduit and has several advantages:
Liquid-Tight Non-Metallic Conduit
Liquid-tight non-metallic conduit is designed for use in environments where moisture could become an issue. This type of conduit must be used in conjunction with liquid-tight fittings.
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.

Common sizes of EMT include 1/2-inch, 3/4-inch, and 1-inch. It is commonly used for exposed indoor wiring runs in residential and light commercial construction.
What is electrical nonmetallic tubing?
Electrical nonmetallic tubing (ENT) is flexible corrugated plastic tubing that is moisture-resistant and flame-retardant. It is easy to bend and installs with snap-lock or glued plastic fittings. Unlike EMT, non-metallic tubing cannot installed in exposed locations, so it is commonly used inside walls.
How many types of conduit are there?
There are seven different types of conduit used commonly in residential and light commercial wiring.
What is rigid conduit?
Another example of a rigid electrical conduit is EMT (electrical metal tubing), which is most commonly made of galvanized steel but can also be aluminum. EMT is also called "thin-wall" conduit because it is thin and lightweight, especially compared to RMC. EMT is rigid but can be bent with a simple tool called a conduit bender.
Can PVC pipe be bent?
Rigid polyvinyl chloride (PVC) is similar to plastic plumbing pipe and is installed with plastic fittings that are glued in place. It can be bent after being heated in a portable heater box. Because the conduit tubing and fittings are glued together, the conduit assemblies can be watertight, making PVC suitable for direct burial in the ground for many applications. It is also allowed in corrosive environments. 7
