  • Patent number: 11385300
    Abstract: The line power and neutral conductors for a circuit interrupter such as a miniature circuit breaker, using ground fault sensing via a current transformer, are arranged as a rigid conductor formed from a flat plate and surrounding and holding an insulated flexible conductor when passing through the Ground Fault Interrupter current transformer. The rigid conductor can provide a shaped current path to maximize the effectiveness of the current transformer.
    Type: Grant

  • Patent number: 7009126
    Abstract: A terminal cover for use on molded case circuit breakers. The terminal cover limits access to circuit breaker electrical terminals and uninsulated portions of electrical conductors entering the terminals. The terminal cover also provides selective access to the terminal binding screws.

  • Patent number: 5678961
    Abstract: A quick change adapter is provided for quickly changing a tool. The adapter includes a tubular-shaped inner member having an axial bore for receiving a shank of a tool, the inner member including a first portion and a second portion, the first portion having a diameter which is greater than a diameter of the second portion thereby defining a shoulder portion. The first portion includes at least one aperture extending between the outer surface and the axial bore. A ball is retained in the aperture and extends into the axial bore and beyond the outside surface of the inner member. The second portion of the inner member has an end which is adapted to be coupled to a tool chuck. A hollow tubular outer member is slidably mounted around the inner member and has a tapered inner wall therein and an end wall at one of its ends. A spring surrounds the second portion of the inner member and rests against the end wall at one end and rests against the shoulder portion at its other end.
