WARNING: Danger of electrical shock or injury.
Turn OFF power ahead of the panelboard or
switchboard before working inside the
equipment or removing any component
. Do
not remove circuit protective devices or any
other component until the power is turned
OFF.
General
These instructions apply to circuit breaker mounting
hardware kits with catalog numbers AHKE1, AHKEL1,
AHKF1, AHKG1, AHKJ1, AHKLB1, and AHKQ1.
Installation
1. Prepare the module. Remove the side trim and filler
plate from the new circuit breaker position, as shown
in Figure 1. Remove the protective caps or insulating
tape from the tops of the line end posts and discard.
2. Install the circuit breaker. Remove the lug cover(s) on
the circuit breaker, if present, but do not discard. Place
the
ON side of the breaker over the stud posts and
resting on the load-end mounting bracket. Tighten
the line- and load-end mounting screws according to
Table 1. Replace the lug cover(s) on the circuit
breaker.
NOTE: On J-Frame breakers only, the line-
mounting screws are replaced with 5 / 16 -18 nut-
washer assemblies.
3. Wiring the circuits. Refer to the rating label on the
circuit breaker for the proper tightening torque levels.
4. Reinstall the filler plate and side trim. Remove the
breaker plug cap(s) from the filler plate and reinstall
on the module. Reinstall the side trim plate(s).
Attention – Procedure for Aluminum
Terminations
1. Strip the insulation, being careful to not nick the wire.
2. Clean the wire strands with a wire brush.
3. Thoroughly coat the stripped conductor with a
suitable antioxidant compound, such as ALNOX or
PENETROX A13.
4. Insert the conductor and tighten the connector screw
to the torque indicated on the rating label.
