A ground assembly for movable member includes an electrical ground connection that does not interfere with the movement and operation of the movable member. The movable member can be a sliding member, such as a sliding barrier, gate or closure member. In one embodiment, the ground assembly includes an electrical connector that moves relative to a fixed electrical grounding member. The electrical connector is fixed to the movable member and movable relative to the grounding member. The electrical connector moves along a length of the grounding member while maintaining contact with the electrical grounding member to provide a continuous grounding connection during movement of the movable member. In one embodiment, the fixed electrical grounding member is oriented with a longitudinal length parallel to the direction of movement of the movable member where the electrical connector of the movable member moves or slides along the length of the fixed electrical grounding member. In another embodiment, the electrical connector is fixed to the grounding member and the movable member includes a surface that slides in contact with the electrical connector by movement of the movable member relative to the grounding member.

A slidable current collector has frame formed as central substrate and sloped shoulders on opposing lateral sides of the central substrate. Electrical terminals pass through orifices arranged in at least two rows within the central substrate. At least one bumper is disposed on an underside of the central substrate between the at least two rows. During sliding on a power rail, the electrical terminals contact a rail surface, and the current collector can shift laterally on the rail surface across a distance between the bumper and one of the sloped shoulders. If disengagement of the electrical terminals from the rail surface occurs, angles on the sloped shoulders and the at least one bumper resist excessive lateral shifting and urge the electrical contacts to reengage with the rail surface.
