<P>PROBLEM TO BE SOLVED: To provide a distribution board in which the number of connecting points of conductive bars is reduced, the cost is reduced by largely shortening an assembling time by reducing the number of part items, little influence is exerted upon an apparatus by suppressing a rise in temperature in the distribution board as well as a burnout accident is prevented, a neutral line open-phase accident is prevented, and further, a yield in operating the conductive bars is improved. <P>SOLUTION: Branch breakers 6 that branch a power supply from a master breaker 7 and supply power to load circuits are arranged in a box body 2 in two rows at an arbitrary interval in a state that terminals on power-supply sides are opposed to each other bilaterally or vertically symmetrically. The master breaker 7 and the branch breakers 6 are connected by the conductive bars 8a, 8b and 8c integrally formed of a master bar section 9 arranged in the middle of the branch breakers 6, connecting bars 10 that connect the master breaker 7 in a state that the master breaker is shifted relative to the longitudinal direction of the master bar section 9, and branch bar sections 11 that connect the master bar section 9 and the branch breakers 6, all of which are formed by punching a plate material. <P>COPYRIGHT: (C)2004,JPO |
