Abstract
Abstract An apparatus is provided for grounding power distribution cable so that maintenance can be perfomed on power distribution equipment or the cable. The apparatus has multiple wells, at least two of which are adapted to receive any of several types of conductor bushing inserts to match the cable elbows, while a third receives a load break bushing which is adapted to receive a grounding elbow.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
128 words
An apparatus for grounding power distribution cable at the connection of connector elbows of the cable to power distribution equipment, comprising: (a) at least three bushing wells for receiving conductor bushing inserts, one of which inserts is a load-breaking insert adapted to receive a connector elbow of a grounding cable, the other inserts being adapted to receive the connector elbows of the cable; (b) at least three electrical conductor means, each mounted in a separate one of said bushing wells for making electrical connection with a bushing inert when inserted therein; (c) bus means joining said electrical conductor means electrically in common; (d) insulative means for containing said bushing wells and said bus means therein; and (e) means for mounting said insulative means to the power distribution equipment.
Claim 2
Independent Claim
128 words
An apparatus for grounding power distribution cable at the connection of connector elbows of the cable to power distribution equipment, comprising: (a) at least three bushing wells for receiving conductor bushing inserts, one of which inserts is a load-breaking insert adapted to receive a connector elbow of a grounding cable, the other inserts being adapted to receive the connector elbows of the cable; (b) at least three electrical conductor means, each mounted in a separate one of said bushing wells for making electrical connection with a bushing inert when inserted therein; (c) bus means joining said electrical conductor means electrically in common; (d) insulative means for containing said bushing wells and said bus means therein; and (e) means for mounting said insulative means to the power distribution equipment.
