The capacity of electrical current supplied to the distribution board needs to be larger than that of the breaker operating
current shown in (2) Distribution Board.
(4) Providing Two Power Supply Systems to the Electrical Power Equipment
To build a redundant power supply system, provide another system of electrical power equipment to serve.
2.3.2 Electrical Power Equipment for 200 V AC
(1) AC Power Supply Cable
Use the power supply cable described below.
Table 2-10 Specifications of AC Power Supply Cable
(2) Electrical Outlet
Use the electrical outlet described below. These electrical outlets are available at general electrical contractors.

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 in case of trouble, which may cause a fire.
Generally, the breaker operating current is larger than the rated current. Check the
specifications of the circuit breaker.
