Safe electrical interconnection box and methods of safe electrical

Abstract

A safe electrical interconnection box includes a rear wall, a front panel and a plurality of lateral walls extending between the rear wall and front panel so as to define an enclosed interior space. The front panel forms part of a cover which is movable sufficiently so as to provide an access opening into the enclosed interior space. At least one and typically three current probe attachment fixtures are located within the interior space, suggestedly mounted on a plate which itself is mounted within the box. Also provided are one or more socket-type electrical connectors with pin receiving holes mounted on the separate plate. Preferably, at least one connector is multi-holed and another is single-holed. In one example, the fixtures and multi-hole connector are coupled with a polyphase high voltage power supply connected through the cabinet with a polyphase high voltage electric motor. Individual leads are run in closed, current carrying loops through separate fixtures from the separate phases of the power supply either directly or typically through current transformers. Individual leads are extended from the separate phases of the power supply to the multi-hole connector in open circuit connections also either directly or through voltage transformers. The single-hole connector is coupled to ground.
