Electrical wiring structure with connection points arranged on side walls and building construction method

An electrical wiring structure with connection points arranged on side walls, comprising:

• a first power wire drawn out of a distribution box and disposed through a first conduit embedded in a concrete-made bottom base or ceiling top of an indoor space;
• a first joint box embedded at a predetermined height in a first side wall formed in the indoor space and electrically connected to the first power wire;
• a first light wire electrically connected to the first joint box;
• and
• a second joint box embedded at a predetermined height in a second side wall formed in the indoor space and electrically connected to the first joint box by a second power wire disposed through a second conduit embedded in the bottom base or ceiling top of the indoor space,
• wherein the first joint box doubles as a receptacle box electrically connected to the first and second power wires.

A method of constructing electrical wiring with connection points arranged on side walls, comprising:

• embedding a joint box at a predetermined height in a side wall formed in an indoor space of a building;
• embedding a conduit immediately below or above the joint box and in a concrete-made bottom base or ceiling top of the indoor space;
• electrically connecting a distribution box to the joint box using a power wire passing through the conduit;
• and
• electrically connecting the joint box to a light box embedded in the ceiling of the indoor space using a light wire,
• wherein the joint box doubles as a switch box configured to switch a light electrically connected to a light box by the light wire.
