The Allen-Bradley Centerline 1500 medium-voltage motor control center helps to increase worker safety with the integrated protective maintenance grounding (IPMG) device. The UL-listed device grounds all load-side connections and load cables with the turn of a handle. This eliminates the need to attach hazardous temporary grounding cables manually. The IPMG device provides a method to ground all load-side connections, including the load cables. It removes the hazardous use of utility-style grounding balls and temporary grounding cable assemblies and provides the ability to ground the output (load-side connections) without opening the power cell door. It also integrates into motor control center power cells.
