PURPOSE:To provide a voltage switcher for a branch circuit, by which the voltage can be switched easily in a single-phase three-wire distribution board. CONSTITUTION:The connection terminals 8 of an N pole main bar 3 and the connection terminals 6 of the main bar 6 on the side remote from a branch breaker 4 are arranged at a constant interval substantially on the same plane. The branch breaker 4 is fixed, at the terminal part 4b thereof, with a branch lead bar 9 which can be connected selectively with any one of the connection terminals 6 or 8 through oscillation around the lower end thereof. This structure allows easy switching of voltage. |
