c. CB4 and CB5 (40- 3-Phase. Each 3-phase circuit breaker (3, Figure 2-3) for Ml 00 and (3, Figure
2-4) for M100 A/P is in series between the bus bars and a 40-amp output connector. These circuit breakers
prevent output power to the connectors from exceeding a current of 40 amps per phase (14.4 kW maximum
load). These circuit breakers allow the operator to turn off power to the load circuits.
d. CB7 and CB8 Ground Fault [GF]. Single-Phase). Each single-phase circuit breaker (4, Figure
2-3) for M100 is in series between the bus bars and a 20-amp output connector. These circuit breakers
prevent output power to the connectors from exceeding a current of 20 amps (2.4 kW maximum load), allows
the operator to turn power off to the load, and interrupt the circuit when a current flow occurs in the ground wire.
e. CB7 and CB8 (20-amp. Single-Phase). Each single-phase circuit breaker (7, Figure 2-4) for M40 A/P is
in series between the bus bars and a 20-amp output connector. These circuit breakers prevent output power
to the connectors from exceeding a current of 20 amps per phase (2.4 kW maximum load). These circuit
breakers also allow the operator to turn off to the load circuits.
f. Ground Fault Test Switch. These switches (5, Figure 2-3) for Ml 00 test the ground fault sensor (trip
indication) for the 20A GF circuit breakers. The M 100 A/P doesn’t have a ground fault circuit.
g. L1, L2, and L3 Phase Indicator Lights. These lights (6, Figure 2-3) for Ml 00 and (5, Figure 2-4) for M100
A/P are connected between neutral and each phase. When electrical power is being supplied to the feeder
center, the lights will illuminate.
2-3. M40 DISE DISTRIBUTION CENTER AND M40 A/P PDISE DISTRIBUTION CENTER.
a. Main Circuit Breaker CB1 (40-amp, 3-Phase). This 3-phase circuit breaker (1, Figure 2-5) for M40 and
(1, Figure 2-6) for M100 A/P is in series between the 40-amp input connector and the bus bars. This circuit
breaker prevents input power to the distribution center from exceeding a total current of 40 amps per phase
(14.4 kW maximum load). This circuit breaker allows the operator to turn off power to all output circuit breakers.
b. CB4, CB6, CB10, CB12, CB14 and CB14 (20-amp, Single-Phase). Each single-phase circuit breaker
(2, Figure 2-5) for M40 is in series between the bus bars and a 20-amp output connector. These circuit
breakers prevent output power to the connectors from exceeding a current of 20 amps per phase (2.4 kW
maximum load). These circuit breakers also allow the operator to turn off power to the load circuits.

c. CB3, CB5, CB7, CB9, CB11, and CB13 (20-amp Ground Fault [GF], Single-Phase). Each single-phase
circuit breaker (3, Figure 2-5) for M40 and is in series between the bus bars and a 20-amp output connector.
These circuit breakers prevent output power to the connectors from exceeding a current of 20 amps (2.4 kW
maximum load), allows the operator to turn power off to the load, and also interrupt the circuit when a current
flow occurs in the ground wire.
