ABSTRACT:
A protective boot of flexible, insulating material for use in covering the grounded portions of a circuit interrupter and thereby preventing accidental shorting between the current carrying sections of the circuit interrupter and the grounded portions. The standard, pole-mounted circuit interrupter consists of a number of movable switches used in high voltage applications where shorting can be extremely damaging to the unit. The protective boot of the invention is fabricated in a number of separate parts which correspond to the individual grounded elements of the interrupter. Thus, when in place, the boot will substantially encase the entire grounded portion providing the requisite insulation. At the same time, due to the number of separate parts of the boot, installation on pole-mounted interrupters is easily accomplished, and at the same time, the moving parts of the switches remain unobstructed.
