  • Patent number: 8953306
    Abstract: 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.

  • Publication number: 20090185336
    Abstract: A mounting assembly includes a DIN rail for removably securing a number of electrical switching apparatus such as, for example circuit breakers, to a panel member of an electrical enclosure. First and second mounting members extend outwardly from first and second ends, respectively, of the DIN rail. Each mounting member has at least one lateral protrusion. The first and second mounting members are, for example, a number of first resilient legs and a number of second resilient legs, respectively, each of which is structured to bias a corresponding one of the lateral protrusions into engagement with one of the coupling elements of the panel member. The DIN rail, the number of first resilient legs, and the number of second resilient legs are structured to removably secure the circuit breakers to the panel member of the electrical enclosure, without requiring a number of separate fasteners.
