XJG Conduit Expansion Joints with Internal Grounding For Rigid Metal Conduit and IMC
Applications:
XJF expansion couplings are used with rigid metal conduit and IMC:
Without the need for an external bounding jumper and clamps (up to 4)
To couple together two(2) sections of conduit subject to longitudinal movement
In long conduit runs to permit linear movement caused by thermal expansion and contraction
On long conduit runs to prevent conduit from buckling and ensuing circuit failures
Indoors and outdoors where conduit expansion occurs and there are wide temperature ranges
In conduit runs that cross structural joints
In conduit runs to prevent damage to conduit supports such as in a building or on a bridge
With optional redundant visible grounding strap
