The first US power plug and socket dated 1904. Several early American electrical plug and socket arrangements were invented by Harvey Hubbell. On 26 February 1903 he filed two patent applications featuring 2-pin plugs and adaptors for using his plugs with existing designs of lamp sockets and wall receptacles.
Hubbell received at least 45 patents, [3] most of which were for electric products. The pull-chain electrical light socket was patented in 1896, and his most famous invention, the U.S. electrical power plug, in 1904. It allowed the adoption in the U.S. of convenient, portable electrical devices, which Great Britain had enjoyed since the early ...
AC power plugs and sockets connect devices to mains electricity to supply them with electrical power. A plug is the connector attached to an electrically-operated device, often via a cable. A socket (also known as a receptacle or outlet ) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit.
The International Electrotechnical Commission publishes IEC 60050, the International Electrotechnical Vocabulary. [2]Generally the plug is the movable connector attached to an electrically operated device's mains cable, and the socket is fixed on equipment or a building structure and connected to an energised electrical circuit.
Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some ...
