ABSTRACT:
A protective shield adapted to be clamped to an electrical hot stick 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 plastic material and a clamping mechanism for securing the plate to a hot stick. An opening in the plate allows for passage of the hot stick through the plate, afterwhich a pivotally mounted clamp arm and bolt arm are secured together about the hot stick. The protective shield provides physical protection to linemen working in live-line or deenergized maintenance situations by acting as a barrier between the lineman and the equipment while providing complete visibility to the task being performed.
