5. Take set screw and shaft collar from hardware kit
and insert set screw into shaft collar. Place square
end of shaft through shaft support bracket then
through shaft collar and into square opening of die
cast pivot link on the operating mechanism attached
to the circuit breaker, as shown in Figure 2-2.
Position shaft collar lightly against the underside of
the shaft support collar and torque set screw
between 28-30 in-lbs.
6. For vertical and horizontal handle mounting orienta-
tion, see Figure 2-5.
7. If adjustable support extension is being used,
tighten securely at this time.
2-3 Installation of Handle Assembly onto Enclosure
Cover
1. To determine where to drill the enclosure door
cover, close the cover with moderate force in order
to cause the point of the shaft to scratch/mark the
paint on the inside of the door.
2. Prior to drilling the 1.50" diameter hole in the cover
door, use correction factor per Table 2.1. Correction
should be made from mark on door (step 1) towards
hinge. Drill 1.50" Dia. hole.
Table 2.1 Correction Factor Table
Figure 2-4 Handle Orientation
3. After the hole is drilled, close enclosure cover
allowing the shaft to stick through the opening.
Check this dimension per Figure 2-3.
4. Close enclosure door. Place gasket/template
supplied in hardware kit or cut out the dotted
line of the shaft outline provided in Figure 4-1.
Place the template over the shaft ensuring the
text/wording is facing outward. With the use
of your fingers remove any play by rotating
the shaft in a clockwise motion. Align the
