5.7.2 Installation of Circuit Breakers and Fuses
5.7.2.1 Plug-in Circuit Breakers
1) Remove the circuit breaker cover panel and the plastic cover(s) from the desired
location(s).
2) Install the circuit breaker(s) by snapping the top terminal onto the upper bus bar and
rotating the unit down until the second terminal snaps onto the breaker termination
post as shown in Figure 5.7-1. The breaker alarm terminals are designed to make
contact with the alarm terminal board as the breaker is snapped into place.
NOTE: Circuit breaker alarm contacts close when the circuit breaker is tripped
but not when it is turned OFF.
***** CAUTION *****
During circuit breaker installation, carefully align the breaker alarm terminals with the alarm
terminal board to avoid breaker terminal damage.
3) Reattach the circuit breaker cover panel.
