![]() ![]() PVC is typically available in Schedule 40 and Schedule 80 options: Schedule 40 is used most often, but Schedule 80 is used when there's risk of damage to the pipes because it has thicker walls. It can be heated and bent and is joined with glued or threaded connections. PVC: Rigid PVC is a plastic pipe similar in size to rigid metal conduit (RMC).This tubing is often called Smurf tubing for its blue color, though it also comes in gray and orange, depending on the manufacturer and/or use. Although the tubing is moisture-resistant and flame-retardant, it's not suitable to exposed locations and should not be installed outdoors or anywhere that may be exposed to the elements. Electrical Non-Metallic Tubing (ENT): Electrical nonmetallic tubing is flexible plastic tubing designed for use inside residential walls or concrete block structures.IMT has largely replaced RMC in new construction, and both RMC and IMC are joined with threaded connections. They are used for the structural piping that houses the wiring for the home's connection to the utility service lines for many overhead services. Rigid Metal Conduit (RMC) and Intermediate Metal Conduit (IMC): Rigid metal conduit and intermediate metal conduit are heavy-duty conduits made of galvanized steel.It has unique connectors and is used when less protection is needed for the conduit, as in indoor settlings. Non-Metallic Liquid-tight Flexible Conduit: Non-metallic liquid-tight conduit is often used in place of liquid-tight flexible metal conduit (LFMC).It is used for outdoor wiring serving air conditioning units and other outdoor equipment. Its close cousin, liquid-tight flexible metal conduit, is a flexible metal conduit covered with plastic sheathing to make it watertight. FMT tubing is commonly used for short runs in exposed locations, such as wiring for garbage disposers and water heaters. Flexible Metal Conduit (FMT) and Liquid-tight Flexible Metal Conduit (LFMC): Flexible metal conduit has a spiral construction which allows the conduit to bend easily, simplifying installation in walls or other structures. ![]() ENT Fittings, Flexible Conduit Fittings, Cover Plates, Conduit Spacers. Outdoors, EMT will typically last a few years-indoors, it'll last indefinitely. This junction box is designed to be installed as a wall mount junction box. EMT is best used indoors for residential and light commercial construction-if it's installed outdoors, it needs to be assembled along with watertight fittings. ![]() Mark the last piece of conduit, starting from the bare threads. Adjust the measurement for the distance the LB protrudes from the wall. for the threading and subtract for the bend. EMT is technically tubing, not conduit, hence the abbreviation uses the letter "T" instead of "C." Because the tubing is thin and lightweight, it is easy to bend with a special tool called a conduit bender. If the LB is held away from the wall by siding, subtract this distance from the measurement.
