(3) Distribution Board
The branch circuit to supply power to the device requires circuit breakers that meet the following specifications.
• Rated breaking capacity: 10 AT with single phase 200 V AC (for a 10 A circuit)
(4) Conditions of the Incoming Power to the Distribution Board
The capacity of electrical current supplied to the distribution board should be larger than that of the breaker operating
current shown in (3) Distribution Board.
(5) Providing Two Power Supply Systems to the Electrical Power Equipment
To build a redundant power supply system, make sure that another system of electrical power equipment is available.
For easy operation, it is recommended that the distribution board should be installed in the
same room as the device or the adjacent room.
Ensure that the capacity of incoming current to the distribution board should be larger
than the breaker operating current capacity. Otherwise, the breakers cannot operate
properly if there is a problem, which might cause a fire.
Generally, the breaker operating current is larger than the rated current. Check the
specifications of the circuit breaker.
