<P>PROBLEM TO BE SOLVED: To detect easily an electric current supplied to an electric apparatus. <P>SOLUTION: A plug for a wiring duct P includes: a contact piece 2 contacting with a conductor 101 of a wiring duct 100; a cable way 3 connecting a power supply cable 150 with the contact piece 2; a current sensor (current transformer) 4 detecting an electric current flowing from the contact piece 2 to the power supply cable 150; and a housing 1 housing the contact piece 2, the cable way 3, and the current sensor 4 therein and into which the power supply cable 150 is led. That is, the current sensor 4 is housed in the housing 1. Thus, unlike conventional electric apparatuses, a box 130 incorporating the current sensor (current transformer) does not need to be installed on a top surface of each server rack 120, and the electric current supplied to an electric apparatus 170 is easily detected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
