摘要： A Fusible electric switch is herein described for increased ratings within industrial electrical distribution circuits by the provision of an arc exhaust gas controller. The arc gas controller cools and deionizes the arc gases that are generated upon separation of the switch contacts and exhausts the gases in a predetermined direction outside the switch enclosure. Fuse pullers are arranged at one end of each of the switch fuses to facilitate both installation and removal of the fuses.

摘要： In a circuit breaker load center there is provided a main lug assembly constructed for interchangeable installation with a main circuit breaker. The lug assembly comprises an insulative mounting block to which are secured a pair of conductive straps in closely spaced parallel relation. An upstanding barrier wall integral with the block provides electrical isolation between the straps, as well as between wire connector lugs affixed in electrical connection to one end portion of each strap. The block is notched to expose the other terminal end portion of each strap for electrical connection to terminal ends of the load center busbars.
