Abstract
An improved device for bonding a grounding electrode conductor to the enclosure of an electric service box comprising a grounding electrode conductor and a two part tapered metal sleeve connector assembly into which the conductor is inserted. A threaded fitting extends over the sleeve and a nut compresses the fitting and sleeve around the grounding electrode conductor. Both the conductor and the connector assembly are designed in conformance to the 2002 National Electric Code and the UL's Laboratory Manuals for connectors and grounding equipment.
Claims7
A device for bonding a grounding electrode conductor to a metal enclosure such as an electric service box in conformance to the National Electric Code of 2002 and the Underwriter's Lab Manuals for connectors and grounding equipment comprising:
- a) a grounding electrode having a grounding electrode conductor affixed thereto, said conductor extending from said grounding electrode to said enclosure,
- b) said enclosure having an inlet to which a metal press sleeve connector assembly can be affixed, said connector having an aperture thereat for receiving said conductor and including a two part tapered sleeve having a smooth external surface, a threaded fiitng having one end tapered in conformance with the taper of the sleeve, a nut inserted thereover, said nut compressing said fitting and said sleeve with a minimum torque of 150 inch pounds around said conductor as it is rotated toward said service box, said fitting and said sleeve being in electrical contact with said conductor.
- c) a flange integral with the fitting and located adjacent an outer side of said metal enclosure, said fitting's extending into said enclosure being limited by said flange, said connector assembly being secured to said enclosure by a lock nut, said conductor having an end that passes through said aperture in said sleeve and being fastened to a bus bar in said enclosure.
- d) said press sleeve connector assembly and said conductor being rated for a minimum of short time test current and available fault current
