PROBLEM TO BE SOLVED: To provide a distribution board which is provided with wire inserting knockouts having large effective areas in spite of a small base of a height semiburyable in a thin wall, and facilitates wiring. SOLUTION: A distribution board is provided with a base 1 in the shape of a thin box having an opening in the front, and wire inserting knockout portions 1a formed continuously in the side surfaces and bottom surface and having L-shaped cross sections, a chassis 2 having an apparatus fitting part 2a being in the base 1, a master breaker 3 and a plurality of branch breakers 4 fitted to the chassis 2, and a cover 7 arranged in front of the base 1 detachably and attachably. At least, a considerable part of the base 1 is buried in a thin wall 10, and semiburied fitting is feasible. When a current limiter of a high fitting height is fitted, it is dealt with making the cover 7 and door 8 as common components, by forming a peripheral stepped part 1b by an integrated body or by an adaptor type on a more front side than the knockout portions 1a of the base 1 having L-shaped cross sections. |
