Circuit Breaker
Panel
There are two Power Distribution Frames for each Control and
Distribution Bay. The first six circuit breakers feed Power
Distribution Frame #1 and circuit breakers 7 - 12 feed Power
Distribution Frame #2. See Figure 7-19. Each circuit has a 150
amp, 50mV shunt associated with it that is located in the Power
Distribution Frame.
1. Precharge the Power Distribution Frame buses as follows:
a. Rotate the CAP/CHG rotary switch to circuit #1.
b. Depress the CAP/CHG pushbutton switch; the red LED
lights, then extinguishes.
c. With the CAP/CHG pushbutton switch depressed,
operate circuit breaker #1 to the On position.
d. Release the pushbutton switch.
2. Check that the appropriate bus is powered at the Power
Distribution Frame. A green LED on the front of the Power
Distribution Frame will light, indicating the bus that has
been energized. Refer to Figure 7-19.
3. Repeat Steps 1 and 2 for all circuit breakers that are
electrically connected to the Power Distribution Frames.
