<P>PROBLEM TO BE SOLVED: To aim at providing a low cost and compact adapter for connection of a watt-hour meter which can inhibit beforehand generating abnormal voltage by connection failure of grounding-side conductor. <P>SOLUTION: In the adapter 10 for connection of the watt-hour meter 100 which measures a consumed electric power quantity and intervenes between a commercial power source which supplies electric power with a single-phase three-line type and a load facility which consumes the supply power, the adapter includes: input conductors 121, 123 from the commercial power source and output conductors 125, 127 into the load facility which are connected into terminals 111, 113 and 115, 117 at a connection terminal stage 102 of the watt-hour meter, respectively, and are intervened the watt-hour meter; a pair of connection terminals 11, 12 which makes a direct continuity of the neutral line of an input conductor 122 from the commercial power source with the neutral line of an output conductor 126 to the load facility; and a conduction terminal 13 which makes a continuity with a neutral line by connecting a conduction conductor 19 from the input terminal 112 for the neutral line of power source at the connection terminal stage of the watt-hour meter. <P>COPYRIGHT: (C)2011,JPO&INPIT |
