WIRING UNIT IN DISTRIBUTION BOARD BREAKER FOR UNINTERRUPTIBLE POWER SOURCE EQUIPMENT

PURPOSE:To improve the reliability by connecting input terminals through a conductive comb type bar comprising a linear section and terminal holes in branch section then bending single phase of the comb type bar in the vicinity of the root of the branch section and maintaining an insulation distance in the linear section. CONSTITUTION:A comb type bar 11 comprises one linear section 11a, a plurality of branch sections 11b extending laterally in same direction, and terminal holes 11c at the tip of the branch section, and the comb type bar 11 is made of conductive flat board. The terminal hole 11c of the comb type bar 11 is connected with U-phase input terminal 3u of a distribution breaker. When the branch section 11c of the comb type bar 11 is bent in the vicinity of its root section, it is deformed into V-phase comb type bar 12. The comb type bars 11, 12 are arranged, respectively, in two stages which are connected through a connecting bar 13 then connected through a wire 7 with the output terminals U, V of the main terminal block 1 of a power source equipment.
