What is EMT Conduit?

EMT conduit (Electrical Metallic Tubing) is a light, steel or aluminum tubing used to protect and route electrical wiring, typically in dry indoor locations.

Definition

Electrical Metallic Tubing (EMT), commonly referred to as thin-walled conduit, is a type of electrical tubing/pipe made from aluminum or steel. Unlike rigid conduit, EMT is unthreaded, which makes it lighter and easier to work with. In smaller diameters, it can be bent on-site using a conduit bender to form angles and offsets, eliminating the need for pre-made elbows. It is secured using non-threaded fittings and is widely used in both commercial and residential electrical installations.

Purpose

EMT encloses electrical conductors within a protective pathway. This limits the risk of physical damage from impact and supports safer installation within structures.

Examples of Use

In commercial spaces such as retail spaces, public facilities, and offices, EMT is put to use frequently for routing electrical wiring. Basements and garages are among the most common residential applications. In industrial settings, warehouses and workshops install it near machinery or in areas that see frequent traffic. Renovation projects favour EMT as well, given that it bends on-site and assembles without threaded connections.

Notes

EMT conduit is best suited for dry, indoor applications.
It is lighter and easier to install than rigid conduits, which makes it a cost-effective option.
On-site bending using a conduit bender allows for custom angles without the need for pre-fabricated fittings.
