We need a combination coupling (C) to join a section of rigid conduit to a section of EMT.
Electrical conduit is a durable tubing or other types of the enclosure which used to protect and provide a route for individual electrical wiring conductors. Electrical metallic tubing (EMT), also called thin-wall is a listed steel raceway of the circular cross section. EMT is unthreaded and has 10′ of long.
We need a combination coupling (C) to join a section of rigid conduit to a section of EMT. Combination Coupling is designed to join EMT to rigid conduit and flexible metal conduit and it also provides the grounding between them.
Combination couplings are made from material steel and zinc die cast with size 3/8" to 1"
