Guard against the Breaker unintentionally
OPENING during the following steps. Keep
hands and fingers away from the Breaker
Crossbar.
J. Manually raise the DTA Assembly Reset Spring
until DTA flange nut touches Trip Finger.
Measure this movement at the end of the DTA
reset spring. The movement should be within
the range of 0.19" to 0.56". This corresponds to
a VERTICAL GAP of 0.06" and 0.19" from the
Trip Finger to the DTA flange nut.

24 VDC to DTA terminals.

DTA Reset Arm to the Cross Bar with the bolt
just removed. After tightening, be sure to lock
the bolt head with the locking clip.

Breaker then tripping with the DTA per Step K),
