2.2 Electrical Service Recommendations
It is recommended that each 400-Watt subsystem power source be equipped with one
of the circuit breaker configurations shown in Figure 2, installed in a load center with a
master mains switch or breaker. This arrangement permits service and maintenance of
the subrack assembly without the necessity for removing power to the entire site, and
ensures continuous coverage in the event that one of the two circuit breakers should
trip.
