Which statement is true about Type IMC?

• A. It is made of plastic.
• B. It is lighter than RMC.
• C. It is designed for indoor use only.
• D. It can be used above and below ground.

Answer: (B)

Type IMC, or Intermediate Metal Conduit, is indeed lighter than Rigid Metal Conduit (RMC). This lightweight nature is one of the defining characteristics of IMC, making it easier to handle and install compared to the heavier RMC. IMC is constructed from thinner walls, which contributes to its reduced weight while still providing ample protection for conductors and supporting equipment. The other choices don't apply to IMC: it is not made of plastic, as it is a metal conduit; it is suitable for both indoor and outdoor installations, so its application is not limited to indoor use only; and while it can be used in various environments, it is not confined to above-ground installations. Thus, its lightness relative to RMC highlights one of its practical advantages in wiring applications.
