2-1. M200 DISE FEEDER CENTER AND M200 A/P PDISE FEEDER CENTER.
a. Main Circuit Breaker (CB1) . This 3-Phase circuit breaker (1, Figure 2-1 for M200) and (1, Figure 2-2) for
M200 A/P is in series between the 200-amp input connector and the bus bars. This circuit breaker prevents
input power to the distribution center from exceeding a total current of 200 amps per phase (72 kW maximum
load). This circuit breaker allows the operator to turn off power to all output circuit breakers.
b. CB4. CB5. and CB11 (100-amp, 3-Phase). Each 3-phase circuit breaker (2, Figure 2-1 ) for M200 and
(2, Figure 2-2) for M200 A/P is in series between the bus bars and a 100-amp output connector. These circuit
breakers prevent output power to the connectors from exceeding a current of 100 amps per phase (36 kW
maximum load). These circuit breakers allow the operator to turn off power to the load circuits.
c. CB7. CB8. CB9. and C10 (60-amp. 3-Phase).Each 3-phase circuit breaker (3, Figure 2-1 ) for M200
and (3, Figure 2-2) for M200 A/P is in series between the bus bars and a 60-amp output connector. These
circuit breakers prevent output power to the connectors from exceeding a current of 60 amps per phase (21.6
kW maximum load). These circuit breakers allow the operator to turn off power to the load circuits.
d. CB6 (20 amps Ground Fault [GF], Single-Phase). This circuit breaker (4, Figure 2-1 ) for M200 is in
series between the bus bars and the 20-amp output connector. This circuit breaker prevents output power to
the connector from exceeding a current of 20 amps (2.4 kW maximum load), allows the operator to turn off
power to the load, and also interrupts the circuits when a current flow occurs in the ground wire.
e. CB6 (20-amp, Single-Phase). This single-phase circuit breaker (7, Figure 2-2) for M200 A/P is in series
between the bus bars and a 20-amp output connector. This circuit breaker prevent output power to the
connector from exceeding a current of 20 amps per phase (2.4 kW maximum load). This circuit breaker also
allow the operator to turn off to the load circuit.
f. Ground Fault Test Switch. This switch (5, Figure 2-1 ) for M200 tests the ground fault sensor (trip
indication) for the 20A GF circuit breaker. The M200 A/P does not have a ground fault circuit.
