A method and an apparatus of connecting a main bus-bar with a sub bus-bar for distributing power supplied to a distribution switchboard are provided to easily connect a main bus-bar with a sub bus-bar by using a fastening unit, an insulation unit, and an insulation support plate. After an insulation unit(10) and an insulation support plate(20) are interposed between a main bus-bar and a sub bus-bar, the main bus-bar and the sub bus-bar are connected to each other by a fastening unit(30). Several insulation units are collinearly stacked, so that plural main bus-bars and plural sub bus-bars are stacked one by one and are connected to each other. |
