<P>PROBLEM TO BE SOLVED: To provide an AC distribution board in consideration of safety which suppresses voltage drop by shortening the wiring length to the extent possible, reduces manpower and decreases the weight of the distribution board. <P>SOLUTION: Circuit breakers 3 are connected in parallel from an input side AC power supply to be lined up end to end. Below the circuit breakers 3, output terminal blocks 4 corresponding to the number of the circuit breakers lined up end to end are lined up side to side in the direction perpendicular to the circuit breakers to be wired from respective circuit breakers, while output terminal blocks 4 in three lines, of which the number is obtained by adding the number of phases of power supplies to the number of grounds, are arranged side by side in a plurality of stages. An upright set of unit 5 is configured by the circuit breakers 3 in single vertical line and the output terminal blocks 4 positioned below the circuit breakers 3 and wired from the circuit breakers. <P>COPYRIGHT: (C)2008,JPO&INPIT |
