Abstract
Contact alignment structure aligns a contact of a circuit breaker. The circuit breaker includes the contact fixed to a conductor, and a resistor tube having a longitudinal axis. The contact alignment structure includes a tube clamp assembly for selectively coupling to a periphery of the resistor tube. A rocker assembly is coupled with the tube clamp assembly and with the conductor so that the conductor is supported by the rocker assembly only at one end of the conductor. When the rocker assembly is coupled to the conductor, the tube clamp assembly can be rotated about the periphery of the resistor tube to change a position of the contact in a first degree of freedom, and a portion of the rocker arm assembly can be moved to change a position of the contact in a second degree of freedom that is parallel to the longitudinal axis of the resistor tube.
