Abstract
A miniature circuit breaker incorporating ground fault protection and arc fault protection has a common rocker button for selectively actuating a ground fault test switch and an arc fault test switch. A leaf spring seated in a groove in the rocker button has converging legs which bias the common rocker button from the ground fault test position, and in the opposite direction from the arc fault test position, respectively, toward a central, neutral position.
