Remove the right hex bolt from the bottom of
each Breaker Stud. The PT Wires are marked
for connection to Phases 1, 2, and 3 with
corresponding numbers.
Note: Before cutting the PT Wires, verify
the Phase Convention used on the Breaker
Application.
Route the wires to a position suitable for
attachment to the bottom Breaker Studs. Move
the PT Wire markers to a position where they
will still be attached to the wires after cutting.
Cut the wires to length, strip each wire .250",
and install a .250" ring terminal on each wire.
Connect the wires to the bottom Breaker Studs
using the original mounting hardware.
F. Remove the nut securing the spring to the
Reset Shaft. Make sure that the spring and
washers stay in place on the Reset Shaft. While
reinstalling the DTA Assembly, align the Reset
Shaft with the slot in the Reset Arm.
G. Align the DTA Assembly with the existing holes
in the right Breaker Frame and the hole just
drilled in the front Breaker Frame.
H. Secure the DTA Assembly to the Breaker, as
shown, using the (3) .250-20 × .750" bolts,
(6) flat washers, (3) lock washers, and (3)
nuts supplied. Do not tighten the hardware at
this time.
Step 9: Setting the Gap and Cage Height
A. With the DTA Assembly mounting bolts
loosened, move the front of the DTA Assembly
up or down until a gap of .06" to .09" is
achieved between the Trip Finger and Breaker
Push-to-Trip Mechanism. Tighten the mounting
bolts. Recheck the gap to assure that it has not
changed.
B. The cage height on the Reset Shaft should be
approximately .41" to .47". If the cage height is
incorrect, loosen the lock nut on the Reset Shaft
then turn the adjusting nut until the correct cage
height is achieved. Tighten the lock nut.
