Final Answer:

A type of conduit that has a wall thickness less than that of RMC but thicker than EMT is IMC (Intermediate Metal Conduit).

Explanation:

Intermediate Metal Conduit (IMC) is a type of electrical conduit used for protecting and routing electrical wiring in buildings and other structures. IMC falls between Rigid Metal Conduit (RMC) and Electrical Metallic Tubing (EMT) in terms of wall thickness.

RMC is the thickest and heaviest type of conduit and is used in applications where maximum protection is required. EMT, on the other hand, has a thinner wall and is often used in less demanding environments.

IMC strikes a balance between these two. It has a thicker wall compared to EMT, providing better protection for wiring, especially in areas where there might be exposure to physical damage or environmental factors. At the same time, IMC is lighter and easier to work with compared to RMC, making it a practical choice for many electrical installations.

IMC is typically made of galvanized steel and is compatible with the same fittings and connectors used for RMC. This makes it a versatile choice for electricians and contractors when they need a conduit with intermediate protection levels.

In summary, IMC, or Intermediate Metal Conduit, is the conduit type that falls between RMC and EMT in terms of wall thickness, offering a balance of protection and ease of installation for electrical wiring applications.
