INDOOR ELECTRIC POWER WIRING AND JOINT BOX, WIRING ADAPTER, SWITCH MEMBER, AND TABLE TAP UTILIZED FOR INDOOR ELECTRIC POWER WIRING

摘要

In indoor electric power wiring, a common mode choke is connected to midstream of an electric power wiring line. A common mode choke, which is connected, is set up in such a manner that a common mode impedance value in a carrier frequency band of electric power line carrier communication which utilizes this indoor electric power wiring becomes a sufficiently large value. The common mode choke is disposed in joint boxes 91, 92, outlets 2a, 3a, 3b, 3c, 3d, and so on, which are branch sections for connecting a power supplying side line and a plurality of power supplied side lines.
