Electric Facility Materials

Electrical wiring components are mainly electrical products for construction. In Japan, they are classified into A category, which consists of devices, B category, which consists of devices that are not consumables, and C category which consists of consumables. These products are installed by qualified professional electricians when preparing the building for power usage. An example of these products is a switch for turning on and off lights, etc. The 3-way switch can regulate current to a load at 2 points. Double-pole switches do not generate voltage on the load side and are suitable for controlling 200-V appliances. Electrical wiring components also include outlets that supply power to household electrical appliances. The number of receptacles and their shapes may vary according to usage conditions. Other electrical wiring components include power distribution boards that divert wiring, breakers that detect abnormalities in the circuit and interrupt current, and more.
