ABSTRACT:
An electrical expansion coupling comprising a housing having a first end and a second end, with a first end cap secured to the first end with a first sealing gland positioned therein, and a second end cap secured to the second end with a second sealing gland positioned therein. The expansion coupling includes an axial sliding ground plate adapted to receive an electrical conduit positioned within the first end of the housing, and a stationary ground plate adapted to receive an electrical conduit positioned within the second end of the housing. The expansion coupling further includes a grounding member electrically connecting the axial sliding ground plate and the stationary ground plate, and an anti-rotation mechanism adapted for preventing relative rotation of the sliding ground plate and the stationary ground plate when a conduit is threaded into the sliding ground plate or the stationary ground plate.
