PROBLEM TO BE SOLVED: To obtain an easy-to-handle, safe branch breaker which makes it a technical issue for solidifying the combination of a main bar and branch breaker by unit of one or a pair of branch breaker, and to obtain a distribution board that makes it possible to save cost and space and to add on branch breakers freely. SOLUTION: A branch breaker is made up of main bar function parts, and breaker function parts having electric wire terminals solidly embedded and fixed in an electrically connected state to a base body of an electrically insulated material. A distribution board is constituted by connecting the main bar function parts in series making use of wall sockets and plugs and by linking the branch breakers in column. This constitution makes it possible to deal with the main bar function parts and breaker function parts in a one-to-one correspondence. |
