Which statement is true about Type IMC?

Type IMC, or Intermediate Metal Conduit, is indeed lighter than Rigid Metal Conduit (RMC). The difference in weight stems from the manufacturing process and the materials used in each type of conduit. IMC is designed to provide a balance between durability and weight, making it easier to handle and install compared to RMC, which is heavier due to its thicker walls and more robust construction.

The design and material composition of IMC allow it to be used in various applications, including both indoor and outdoor settings, as long as it is appropriately protected against the elements. However, it is not made of plastic; it is typically constructed from galvanized steel or aluminum, thereby providing certain mechanical protection benefits. Moreover, while IMC can be utilized above and below ground, this does not pertain to its lighter weight compared to RMC, confirming the correctness of the chosen statement.
