What is the use of flexible metallic tubing in electrical wiring installation?
What is Flexible Metal Conduits. Flexible Metal Conduit, is heavy-duty galvanized steel tubing that is installed with threaded fittings. It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment.
What is electrical metallic tubing used for?
Electrical Metallic Tubing (EMT). An unthreaded thinwall raceway of circular cross section designed for the physical protection and routing of conductors and cables and for use as an equipment grounding conductor when installed utilizing appropriate fittings.
How do you install a surface mounted wiring?
Surface-mounted wiring is achieved when you use hollow channel (often called raceway) to extend the circuit. By simply adding a surface-mounted extension box, add a piece of raceway, and add a box to the new location, you’ll have a new outlet in your home in no time at all.
Why is it importance in installing flexible metallic tubing?
Flexible metallic conduits or FMCs are often used in commercial buildings. This conduit is specifically used in areas where it is not possible to use a rigid conduit. It can provide ample strength and protection with the added benefit of flexibility.
What is electrical metallic conduit?
electrical metallic conduit (EMC) Conduit, usually fabricated of steel, which encloses electrical wiring, thereby protecting the wiring from outside damage. Between these two is an intermediate metallic conduit (IMC), which is 25 percent lighter and less costly than EMT; it may be threaded or threadless.
What is the purpose of Article 344?
Rigid Metal Conduit (RMC). A threadable raceway of circular cross section designed for the physical protection and routing of conductors and cables and for use as an equipment grounding conductor when installed with its integral or associated coupling and appropriate fittings.
