Description
The circuit breaker kit provides POWER ON/OFF and cur-
rent overprotection function at the unit. The circuit breaker
kit contains the appropriate circuit breaker, replacement
access cover for the high voltage section of the subbase,
mounting bracket and clips, and required hardware. Select
circuit breaker kits according to unit amperage.
Installation
1. Check circuit breaker for manufacturers name. Select
mounting holes in mounting bracket to match part as
indicated in the following figure (GE and Westinghouse
use outer holes). Secure one of the two small mounting
clips to the mounting bracket. Do not fully tighten the
mounting screw at this time.
2. Position the circuit breaker on the mounting bracket so
that the locking tabs on the small clip (installed in Step
1) hold the circuit breaker on the mounting bracket.
3. Install the second small clip on the mounting bracket,
locking the circuit breaker on the mounting bracket.
Tighten both mounting screws securely.
4. Disconnect electrical power to the unit (if already wired).
5. Remove access cover from subbase.
6. Position the entire circuit breaker assembly in the sub-
base as shown in Figure 2. Using the two screws pro-
vided, secure the assembly to the subbase back wall in
the subbase high voltage section. The large compres-
sion connections should be on the left (“ON” to the left,
“OFF” to the right).
7. Connect the line voltage to the large compression termi-
nals (left of breaker). Connect subbase wiring to the
smaller compression connections (right of breaker). If a
ground lug is provided, ground the lug to the unit.
8. Install the circuit breaker guard and the replacement
access cover for the high voltage section. Install the
assembly over the circuit breaker handle using the two
screws removed from the original access cover.
