Distribution board with uninterruptible socket terminal block

A distribution board comprising:

• an uninterruptible socket terminal block including a plurality of socket terminal connectors, each of socket terminal connectors having a pair of wire-connector terminals extending in directions opposite each other and a plug-connector terminal extending from the conjunction portion between the pair of wire-connector terminals in a direction perpendicular to the pair of wire-connector terminals, the wire-connectors, which extend in one direction, being connected to drop wires for conducting primary electric power and indoor power wires for conducting secondary electric power, and the other wire-connectors, which extend in the other direction, being connected to intermediate wires for connecting the drop wires and the indoor power wires to terminals of a watt-hour meter;
• and
• a power-converting plug including a plurality of plug terminals to be connected to the corresponding plug-connector terminals of the socket terminal connectors, half of the plurality of plug terminals being connected to the other half of the plurality of plug terminals via plug-connecting wires;
• whereby primary electric power from the drop wires is directly transmitted to the indoor power wires when the power-converting plug is coupled to the socket terminal block to cause the plug terminals of the power-converting plug to be connected to the corresponding plug-connector terminals of the socket terminal connectors.
