ABSTRACT:
Electrical insulation and environmental protection for electrical joints between cables and flat conductors in an electric power distribution system is provided by a flexible, electrically insulative boot which has a pair of shell halves joined by a living hinge. The two shell halves have free edges which mate to form a seam when the shell is closed to form an enclosure around the joint. The flat conductor extends through the seam in the rear face of the shell adjacent the living hinge. Pairs of cable openings in the shell halves are spaced along the front face of the boot. Additional faces at each end of the front face also have pairs of cable openings to accommodate angled mounting of the cables. Slits extend from the free edges of the shell halves to the cable openings to allow installation over assembled joints. The cable openings are serrated to accommodate a range of cable sizes. The shell is secured closed by fasteners such as flexible ties which clamp flanges along the free edges of the shell halves together.
