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.
Claims16
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.
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;
- (b) load breaking inserts mounted in each of said bushing wells;
- (c) one of said load breaking inserts comprising a load-breaking insert for receiving a connector elbow of a grounding cable;
- (d) the others of said load-breaking inserts comprising inserts for receiving connector elbows of the power distribution cable;
- (e) bus means joining said electrical conductor means electrically in common;
- (f) insulative means for containing said bushing wells and said bus means therein;
- and
- (g) means for mounting said insulative means to the power distribution equipment.
A method of grounding power distribution cable at the connection of connector elbows of the cable to power distribution equipment comprising the steps of:
- (a) attaching a ground end of a grounding end of a grounding elbow to an electrical ground of the power distribution equipment;
- (b) mounting an insulative block having at least three conductor bushing inserts therein, at least one of which is a load-breaking insert, and all of which are commonly electrically connected, to the power distribution equipment;
- (c) removing a first one of the connector elbows from the power distribution equipment;
- (d) attaching the first of the connector elbows at one of the conductor bushing inserts;
- (e) removing a second one of the connector elbows from the power distribution equipment;
- (f) attaching the second of the connector elbows to another of the conductor bushings;
- (g) attaching the elbow portion of the grounding elbow to a load-breaking bushing insert on the insulative block.
