Abstract
A method and associated apparatus are provided for removing an auxiliary contact device from a motor starter assembly engaged with a motor controller unit of a motor control center. The method includes engaging an extraction tool with a securement member operably engaged between the auxiliary contact device and the motor starter assembly. The extraction tool includes a handle portion and a securement-engaging portion. The handle portion extends along the auxiliary contact device for the securement-engaging portion to engage the securement member. The method further includes exerting an axial force on the handle portion such that the handle portion cooperates with the securement-engaging portion to disengage the securement member from between the auxiliary contact device and the motor starter assembly, and to disengage the electrically-conductive engagement between the auxiliary contact device and the motor starter assembly, to remove the auxiliary contact device from the motor starter assembly.
