Abstract: An arc shield for electrical switching apparatuses is provided. The arc shield comprises a mounting base and a detachable barrier and includes a multi-point mounting system that eliminates the need for hardware and gloves when installing the detachable barrier on the mounting base. The mounting base is formed with a hinge tab and two locking tabs, and the detachable barrier is formed with a corresponding notch and two tab receiving openings formed with retention profile. The notch can be seated on the hinge tab in order to establish a hinge, and once the hinge is established, the locking tabs can be inserted through the tab receiving openings by bending the detachable barrier. Once the bending force is removed, the retention profiles of the locking tabs ensure that the detachable barrier cannot be removed from the mounting base unless a bending force is intentionally reapplied to the barrier.

Abstract: A busway fitting wherein the switch and/or fuse are disposed in a horizontal orientation. As the switch assembly and/or fuse are disposed in a horizontal orientation, the buses coupled to the switch assembly and/or fuse also extend horizontally. As such, the buses coupled to the switch assembly and/or fuse occupy a reduced amount of space. In this configuration, the transition buses may extend in a generally horizontal direction and, as such, the size of the busway fitting may be reduced.
