ABSTRACT:
Two electrical conduit sections are attached to a thermal expansion joint which permits relative axial movement between the conduit sections. One of the conduit sections has an end portion which is axially slidably disposed inside of the expansion joint. A ring shaped grounding element is mounted on a screw thread formed in that slidable end portion and is disposed in sliding connection with a cylindrical surface of the joint which surrounds the slidable end portion.
