How to Install a Rigid Conduit

Rigid-steel conduit is a heavy pipe threaded at both ends used to provide protection to electrical wires that run though the conduit itself.

Conduits are connected to electrical boxes, such as outlets.Conduits are connected to electrical boxes, such as outlets.
Installing rigid conduit will provide the best protection for electrical wires compared to other types of conduit such as PVC conduit. Installing rigid conduit can be difficult for those without practice but with the right tools and directions it can be done.

Plan the path of the electrical conduit from the electrical panel box to the electrical box that you are installing the conduit to. With a pencil, mark the path along the wall that the conduit will run. Try to mark a path that is as straight as possible to the box without any obstacles along the way.

Place the conduit along the path. Begin working from the electrical panel. Bend the conduit with the conduit pipe bender as needed. To bend the conduit, place it through the bender and leverage the bend with the handle of the bender.

Secure the conduit to the wall with a conduit clip every 12 inches. If securing the conduit to a masonry wall, pre-drill with a masonry bit then use a masonry screw to secure the clip.

Connect two pieces of conduit by twisting a coupling on the end of the installed conduit. Twist the new piece of conduit to the coupling.

Cut away excess conduit with the hacksaw.

Push the last piece of conduit through the electrical box and secure it in place with an electrical box conduit lock nut. Twist the conduit lock nut on the end of the conduit sticking through the electrical box. The conduit should stick into the box no more than 1/2-inch.
