How Do You Join Rigid Electrical Conduit?
Working with rigid electrical conduit requires mastering the use of some tools that you may more likely associate with the plumbing trades than the electrical trades. RMC (Rigid Metal Conduit) is joined with threaded couplings, preformed threaded elbows, and threaded condulet bodies. RMC come in 10-foot sticks that are threaded on both ends, but the electrician frequently has to cut the conduit into shorter lengths and then rethread it by hand or with a power threading machine. Unless you work with conduit day in and day out, you will probably do it by hand. The procedures are simple, but this is one of those skills where practice does make perfect. Measure and mark the RMC to length and then secure it in the tripod pipe vice. Secure it in the vice so the waste portion is free.
