Abstract: Method and apparatus for reducing the minimum clearance needed between an electrical conductor and ground in switchgear and similar electrical isolation equipment provide a bus-connector having an extended toroidal shape that is designed to allow the size of the switchgear cabinet to be reduced while complying with industry-standard performance requirements. The toroidal shaped bus-connector has mostly or only smooth and rounded surfaces so there are no hard or sharp edges or corners from which electrical discharge from/to ground or other conductors may occur. The shaped bus-connector also has an elongated body that produces an offset connection resembling a “Z,” which allows power buses and breaker terminals that do not vertically line up to connect.
