Claims16
A cable joint assembly for an electrical distribution system, the cable joint assembly comprising:
- a unitary crab joint composed of a first end and a second end having a plurality of apertures composed of a plurality of legs, each including a channel for receiving a plurality of cable connections to said unitary crab joint;
- an intermediate housing;
- a junction plate located in said intermediate housing for establishing connections thereto;
- wherein said plurality of apertures are positioned in a rectangular configuration wherein at least one of the plurality of apertures is positioned at top of said unitary crab joint positioned substantially along the centerline of said unitary crab joint as a bus connection, and
- further wherein the cable connections extend outwardly from said unitary crab joint.
A cable joint assembly for an electrical distribution system, the cable joint assembly comprising:
- a unitary crab joint composed of a first end and a second end having six apertures composed of a plurality of legs, each including a channel for receiving a plurality of cable mains connections to said unitary crab joint;
- a single non-limitered bus aperture composed of a leg, including a channel for receiving a bus connection to said unitary crab joint;
- an intermediate housing;
- a junction plate located in said intermediate housing for establishing connections thereto;
- and
- fusing protectors;
- wherein said plurality of apertures are positioned in a rectangular configuration,
- wherein said single bus aperture is positioned at top of said unitary crab joint positioned substantially along the centerline of said unitary crab joint as a bus connection, and
- further wherein the cable mains connections extend outwardly from said unitary crab joint.
A method of establishing an electrical connection comprising the steps of:
- connecting a plurality of cable mains to a unitary crab joint composed of a first end and a second end having six apertures composed of a plurality of legs, each including a channel for receiving a plurality of cable mains connections to said unitary crab joint;
- a single ring bus aperture composed of a leg, including a channel for receiving a bus connection to said unitary crab joint;
- an intermediate housing;
- a junction plate located in said intermediate housing for establishing connections thereto;
- and fusing protectors;
- connecting a single ring bus to said single bus aperture, wherein said single bus aperture is positioned at top of said unitary crab joint positioned substantially along the centerline of said unitary crab joint as a bus connection.
