PROBLEM TO BE SOLVED: To provide a plug socket capable of measuring the entire passing current in the plug socket by using a clamp type ammeter, and of individually measuring a current value flowing in each electric wire group branched from a power supply bus.SOLUTION: A rack plug socket comprises: a plurality of insertion ports 101A and 101B inserted with power plugs of various equipment; receiving blade terminals arranged in a housing opposedly to the respective insertion ports 101A and 101B; and a plurality of electric wire groups A and B branched from a power supply bus S connected with a supply power source V, and electrically connected with the receiving blade terminals for each group of the plurality of insertion ports 101A and 101B. Further, the rack plug socket comprises current measurement parts for the respective electric wire groups, arranged on a surface of the housing, and each configured so that one electric wire of each electric wire group A, B connected with the receiving blade terminals is inserted therein, and each formed in such a shape that a clamp type ammeter for measuring a current value flowing in the electric wire can clamp, like inverted-C marks 1, 2, and 3. |
