1-2 EMT Conduit

EMT conduit is a light-gauge pipe often referred to as thin-wall conduit (Figure 1-2). The wall thickness of EMT conduit is about 40 percent less than that of rigid-steel conduit, and because of the thickness of EMT conduit, it can be easily bent. Article 348 in the NEC covers EMT conduit.
