Capacitor Charge
For initial powering of high inrush loads a charge feature is
available with List 20 circuit breakers. One Capacitor Charge
Panel, List CA, is required for each plant in addition to the
charge feature on the circuit breakers in order to provide the
Capacitor Charge feature.
Load precharging procedure
Precharging is normally required before connecting loads with
high inrush current characteristics through circuit breakers to
avoid nuisance tripping of the breaker. These instances include
startup, connection after manual disconnect, and connection
after circuit breaker electrical trip.
The procedure to precharge a load is as follows:
1. Verify that the affected equipment is ready to accept dc
power.
2. Locate the rotary slot selector and charge switch in the
middle of the circuit breaker distribution panel. L-AA
through AH KS22010 circuit breakers are numbered from
left to right and L-AM through AX KS22012 circuit
breakers are lettered from left to right and correspond to
the rotary selector.
3. Select the circuit breaker with the rotary switch.
WARNING!
Do not attempt to turn the rotary switch while holding the
charge button depressed. Damage to the rotary switch may
result.
