What is the difference between EMT conduit and rigid conduit?
The main difference between EMT conduit and rigid conduit lies in wall thickness, strength, and application.
EMT conduit has a thinner wall, making it lighter, easier to install, and more cost-effective for indoor applications. Rigid conduit has a much thicker wall, providing higher mechanical strength and better protection in harsh environments such as outdoor, underground, or heavy industrial installations.
In practice, EMT is commonly used for commercial interiors, while rigid conduit is selected when maximum physical protection is required.
