Abstract: A distribution board enabling a watt-hour meter mounted thereon to be easily replaced without interrupting the supply of primary electric power to a consumer's house is disclosed. The distribution board includes a socket terminal block having a plurality of socket terminal connectors, each having a pair of wire-connector terminals and a plug-connector terminal extending from the conjunction portion between the pair of wire-connector terminals, and a power-converting plug having a plurality of plug terminals to be connected to the plug-connector terminals of the socket terminal connectors and connected to each other by plug-connecting wires. Primary electric power from drop wires is directly transmitted to indoor power wires when the power-converting plug is coupled to the socket terminal block to cause the plug terminals to be connected to the plug-connector terminals.
