ABSTRACT:
An apparatus for protecting an operator or maintenance person from electrical shock when working near power distribution facilities. The device is characterized by easily snapping off for access to the electrical circuitry and easily snapping on again to afford the desired protection. The shield is transparent providing the operator with visual access to the electrical circuitry at all times, even when the protective device is in place. The apparatus contains a transparent insulative plate attached to a suitable number of insulative clips. In the preferred mode, these clips are positioned to snap onto cartridge type fuses in a multiphase fuse panel. When snapped in place, the clips hold the transparent insulative plate between the electrical circuitry and the operator or maintenance person. Test points are drilled through the transparent insulative plate at appropriate locations to provide for the insertion of test probes when the protective device is in place. An optional handle may be attached to the transparent insulative plate to assist in installation and removal. An alternative embodiment employs one or more skirts fixedly attached perpendicular to the insulative plate to provide further protection. To provide ease in manufacturing, all components may be molded as a single piece.
