ABSTRACT:
A protective shield that may be secured to an electrical racking rod of the type used for performing electrical work on various types of energized electrical equipment. The protective shield includes a transparent plate formed of an impact resistant, fire retardant material; a clamping mechanism secured to the plate and at least one adaptor for securing the racking rod to the plate. The adaptor is engaged by the clamping mechanism to secure the racking rod to the plate. The protective shield provides physical protection to workers when removing or resetting electrical circuit breakers by acting as a barrier between the worker and the equipment while providing complete visibility to the task being performed. A plurality of adaptors may be provided to enable the plate to be utilized with any one of a plurality of different diameter racking rods.
