De-energize the circuit breaker
Prior to performing any inspection or
maintenance checks, the circuit breaker
must be de-energized and grounded.
Principal steps are outlined below for
information and guidance.
Be sure that the circuit breaker and its
mechanism are disconnected from all
electric power, both high voltage and
control voltage, before it is inspected or
repaired.
After the circuit breaker has been
disconnected (isolated) from power lines,
attach the grounding leads properly before
touching any of the circuit breaker parts.
De-energize the control power to the
circuit breaker.
Review Figure 6: Low-voltage
compartment on page 19. If the circuit
breaker includes the optional capacitor trip
unit, the capacitor must be discharged by
grounding its terminals.
Perform the spring discharge check.
