Claim:
A circuit breaker assembly comprising: a circuit breaker; and a mechanical lug assembly for attachment of power cables, the mechanical lug assembly mounted to the circuit breaker and including a main structural body having a cable-receiving face and a wire-binding face, the cable-receiving face being generally defined by a height and a width of the body, the wire-binding face being generally perpendicular to the cable-receiving face and defined by the width and a thickness of the body, a plurality of cable holes extending through the cable-receiving face, the cable holes including a first cable hole separated by a second cable hole from a third cable hole, each of the cable holes being configured to receive a respective one of the power cables, a plurality of wire-binding holes extending at least in part through the wire-binding face, the wire-binding holes including a first wire-binding hole separated by a second wire-binding hole from a third wire-binding hole, the first wire-binding hole having a first longitudinal axis at an angle that intersects a third longitudinal axis of the third wire-binding hole, and an hourglass-shaped fastener received through the second wire-binding hole along a second longitudinal axis, the hourglass-shaped fastener having an hourglass section with a contour that maximizes a corresponding contour of the first cable hole and the third cable hole.
