POWER WIRING NETWORK DEVICE

The present disclosure aims to provide a power wiring network apparatus capable of constructing a highly portable power wiring network, without the need to maintain infrastructure. A power wiring network apparatus (1, 2) includes a wiring member (10, 10'), including first connectors (12) and a conductive portion (11) electrically connecting the first connectors (12) to enable power supply, and circuit elements each including a second connector (21, 31, 41) mechanically and electrically attachable to any first connector (12). The circuit elements include energy harvesting elements (20) capable of outputting, from the second connector (21), power generated by energy harvesting and load elements (30) capable of consuming power inputted from the second connector (21). At least some energy harvesting elements (20) and load elements (30) are capable of power line data communication via a power line including the first connectors (12) and conductive portion (11).
