The National Electrical Code recognizes Allied IMC for the same uses as RIGID, including all hazardous location (classified) applications.
What is an IMC?
A LIGHTER WIRING SOLUTION WITH STRONG PROTECTION. IMC is manufactured as a cross between EMT and rigid metal conduit (RMC). A slightly thinner gauge than RMC, IMC is light but strong. It has the same electric-resistance welded tube-making process as EMT, but it is threaded like RMC, so the same couplings can be used for both.
Why is IMC bigger?
Because IMC is made of less steel, it has a larger inside diameter — allowing for easier wire pulling.
What is a conduit body?
Also known as conduit bodies, these ports provide access to wire and cable inside metal conduit for pulling, splicing, and maintenance. They are also used to change the direction of a run.
How do compression female straight connectors work?

What is RSC conduit?
The RSC/RMC conduit is manufactured from high-strength steel, and welded by electric resistance welding process.It is zinc coated both inside and outside with hot dip galvanizing in such a way that metal-to-metal contact and galvanic protection against corrosion are provided. The exterior surface of the Conduit adopts a clear post-galvanizing coating to provide further protection against corrosion. The interior surface provides a smooth continuous raceway for easy wire pulling. The ductility characteristics of our conduits help for easy bending, cutting, and threading in the field.
What is RMC in electrical?
Rigid Steel/Metal Conduit (RSC/RMC) is a threaded raceway of circular cross section designed for the physical protection and routing of conductors and cables and for use as an equipment grounding conductor when installed with its integral or associated coupling and appropriate fittings.
