<P>PROBLEM TO BE SOLVED: To provide a home distribution board equipped with a power-supply voltage measuring structure to check a voltage to be supplied to a load circuit with good workability before an operation handle is turned on in a distribution switch gear having a plug-in terminal structure. <P>SOLUTION: The power-supply voltage measuring structure is constituted with a bus-bar side voltage measuring unit installed at each of bus bars in first and second voltage poles to be commonly used to a plurality of distribution switch gears, and a switch-gear side voltage measuring unit installed at the side of a plug-in terminal in the distribution switch gear and individually used in each of the distribution switch gears. One of two test leads for the power-supply voltage measuring structure is brought into contact with the first or the second bus-bar side voltage measuring units, while the other is brought into contact individually with each switch-gear side voltage measuring unit at the side of the switch gear. Accordingly, the power-supply voltage applied between the plug-in terminals of the distribution switch gear can be measured. <P>COPYRIGHT: (C)2011,JPO&INPIT |
