What is GREY conduit used for?
Conduit is the term applied to PVC pipe made for electrical wiring containment. It is usually in a gray color and should be approved by Underwriters Laboratories (UL mark) for the intended application. Gray conduit is not rated for pressure pipe applications and may not be suitable for potable water use.
What are the two classification of electrical conduit?
Electrical Metallic Tubing (EMT)
It is generally made of galvanized steel but can be aluminum as well. EMT is typically described as the “thin-wall” conduit because it is thinner and lightweight compared to RMC. It might also be rigid, but it can easily be bent using a simple tool termed as a conduit bender.
