TEST, then CONNECTED. Fig 42
NOTE: When approaching the CONNECTED position, more torque for turning the racking
handle is normal as the primary finger clusters engage with the AKD-8 or OEM

NOTE: At the end of 37 rotations, the breaker is in its maximum travel position. At this point,
the primary disconnect fingers have completely engaged with the primary bus stabs.
