Claims

[Scope of utility model registration request]

A distribution board equipped with switching equipment for multiple branch circuits in which the main circuit is single-phase three-wire, and phase voltage and 1/2-phase voltage can be arbitrarily selected. Main circuit conductors that are arranged in parallel with both conductors to be connected and a neutral conductor that is connected between the phases and has a 1/2 phase voltage for each of the two conductors in a △ or arrangement with the neutral conductor in the center. a fixed branch conductor branched from at least one of the conductors and connected to one terminal of the switchgear; and a fixed branch conductor branched from at least the other of the conductors toward the neutral conductor side of the switchgear. A connecting terminal is extended so that the neutral conductor and distribution are arranged with respect to the other terminal, and one end can be connected to the other terminal of the switchgear, and the other end is turned over and used to connect the neutral conductor. A two-voltage distribution board characterized by comprising a connection conductor that allows a freely switched connection between the conductor and the connection terminal.
