2.6 RIGID CONDUIT COUPLINGS
2.6.1 Coupling for Rigid Conduit to Rigid Conduit
Figure 2-2 illustrates the relative positions of the components of a coupling used for joining
two lengths of rigid metal conduit. Figure 2-3 shows a sketch of the three components of the rigid
metal conduit coupling and includes a list of suggested sources.
2.6.2 Coupling for Rigid Conduit to Flexible Conduit
Figure 2-4 shows the hardware required to join rigid metal conduit to flexible metal conduit.
The table lists the coupling components used with various sizes of rigid and flexible conduit. Note that
in this assembly the male ferrule (figure 2-5) is used in place of the nipple supplied as part of the rigid
metal conduit coupling (figure 2-3). The male ferrule is brazed to the flexible metal conduit and the
assembly is joined using the same torque requirements for rigid conduit coupling. This assembly
provides the transition from rigid conduit to the short lengths of flexible conduit at terminal points in the
cable run.
