This post explains about Domestic Power Plug. The plug is a movable connector attached to the electrical device, and socket is fixed on equipment or a building structure and connected to the energized electrical circuit. The plug is the male connector with protruding pins that match the openings and female contacts in a socket. Some plugs have female contacts that are used for the earth ground connection. Some plugs have built-in fuses for safety.
Domestic Power Plug Overview
- Domestic power plugs are the invention used to connect an external device to the electrical power source.
- ‘Domestic power plugs’ are known as AC power plugs, plugs, power plugs, electrical plugs, power connectors, and plug tops.
- Two to three pins, commonly made of brass or other conducting material, are typically found on domestic power plugs, which are inserted into specific holes in a socket and when the plug is attached to an appliance, it completes an electrical circuit.
- Domestic power plugs were invented in the 1880s, and T.T Smith of England is said to have invented one of the first plugs in 1883.
- Domestic power plugs were invented as a response to the dangerous use of appliances with the sockets designed for light bulbs.
- As a safety precaution and to prevent electrical shocks, many domestic power plugs feature a pin that directs current away from an appliance during a fault, and may also feature insulators around the pins’ upper section or plugs themselves.
- There are at least fourteen differently pinned domestic power plugs, with around twelve of those commonly used across the globe, and the plugs are categorized by letters from ‘A’ to ‘N’, and the pins range from the rectangular shapes of American plugs to the circular shapes of those in Europe.
- Domestic power plug housings vary in shape and size, and come in different colors, commonly black, white or grey, and are fabricated from polyvinyl chloride (PVC) or other insulating material.
- A globalized standard of domestic power plugs has been seen as a beneficial project, and while the International Electrotechnical Commission (IEC) and others have promoted the idea, and despite persistent efforts to reach an international standard for many years, some of which were hampered by World War II, adoption of such has been so far unsuccessful.
- Universal domestic power plug adapters are available, and these have various pin and socket options so that travelers can use their own power appliances in countries with different socket options.
