Intermediate Metal Conduit is a type of rigid steel raceway used to protect and route electrical wiring. It is lighter and thinner-walled than rigid metal conduit (RMC), making it easier to bend and cut, while still providing a substantial level of protection against impact and corrosion. It is typically joined using threaded couplings and connectors. As an example, in a commercial building, this raceway might be used to run electrical wires from a panelboard to various outlets and lighting fixtures throughout the structure.
The value of this type of electrical conduit lies in its balance of cost-effectiveness, durability, and ease of installation. Its protective qualities help to ensure the longevity and safety of electrical systems by shielding wires from physical damage, moisture, and electromagnetic interference. Historically, the introduction of this product provided a more economical alternative to heavier conduit options without sacrificing essential protective features.
