CONSTITUTION:A distribution board 2, electric supply lines 3, a plurality of plug receptacles C1, C2, C3... are OA apparatus 4, 5, 6 inside or outside an OA room are indicated through patterns. When power is applied to a plug receptacle C, an indicating lamp 7 on the side of the receptacle C is lighted and the power supply for the OA apparatus 6 is ON to light the indicating lamp 8.
