PROBLEM TO BE SOLVED: To reduce manufacturing cost by facilitating processing of a master bar, without enlarging the body of a distribution panel. SOLUTION: A body 2 of a distribution panel 1 includes a master breaker 3, main bars 4a, 4b, 4c connected to the main breaker 3, a branch bar connected to the main bars 4a, 4b, 4c, and a branch breaker 5 which is connected to the branch bar, branches the power of the main breaker 3 and supplies it to respective load circuits. The branch breaker 5 is disposed, so as to be divided into two groups in bilateral blocks inside the body 2. The main bars 4a, 4b, 4c are constituted of first main bars 4aL, 4bL, 4cL disposed in the left block, second main bars 4aR, 4bR, 4cR disposed in the right block, and third main bars 4aC, 4bC, 4cC connecting the first main bars 4aL, 4bL, 4cL, the second master bars 4aR, 4bR, 4cR, and the secondary terminals of the main breaker respectively, and disposed so as to be extended, laminated roughly perpendicularly in the depth direction, with an appropriate insulating distance ensured in a roughly horizontal direction from the secondary terminal of the main breaker 3. |
