PROBLEM TO BE SOLVED: To provide a cabinet panel at a low cost, in which breakers for branching are arranged only on one side of a master bar and voltages 100 V and 200 V are switched over to each other. SOLUTION: Many two-pole breakers 4 for branching are arranged in parallel on one side of three master bars. An L1 phase master bar 2 is the main bar of an L shape of one side existing at a position separated from the breakers 4. Bars 7 for branching, in which connection pawls 6 and screw connection parts 7b for switching 200 wirings are formed in tip parts are arranged on the L1 phase master bar 2. Since parts passing under an N phase master bar 3 are common bars 7 for branching, a part where bar holders for retaining the N-phase master bar 3 can be formed is sharply increased, and manufacture is facilitated. |
