Abstract
Methods and apparatus for facilitating current transmission through a circuit breaker are described. In an exemplary embodiment of the apparatus, a coupler that includes a copper conductive ring having an inner annular wall is provided. The coupler is electrically coupled to the line terminal. A bore extends through the ring, and the bore is sized so that the shaft can extend therethrough. A plurality of copper bristles extend radially inward from the ring inner annular wall, and the bristles are in electrical contact with the conductive ring. The bristles also are in electrical contact with shaft when shaft extends through ring bore. At least some bristles extend sufficiently radially inward from the ring inner wall so that free ends of at least some bristles are in electrical contact with the shaft when the shaft extends through the bore.
