Patent number: 8953306Abstract: A load center featuring a two-piece dielectric barrier that securely retains a plug-on neutral rail and methods of assembling the same. The barrier includes a shield and a base having a protrusion that cooperates with fingers of the shield to securely retain the conductor in the load center. The shield is installed over the base and rests on hooks protruding from the base. This creates a distance between the protrusion and the fingers to allow the conductor to be inserted through a gap between the fingers along the conductor's skinny edge. The conductor rotates 90 degrees until it rests on the protrusion. The base and shield are snapped together, causing the hooks of the base to attach to the shield. At the same time, the fingers of the base move downward to rest against the conductor so that it is sandwiched securely between the protrusion and the fingers.Type: GrantFiled: December 19, 2012Date of Patent: February 10, 2015Assignee: Schneider Electric USA, Inc.Inventors: Kim D. Wheeler, Jeffrey O. Sharp, Jason D. Potratz
