This plug-and-socket system is equivalent to the IEC "Plug Type D" system. [23] SANS 164-4: Dedicated System, 16 A 250 V [24] [25] These plugs and sockets, unique to South Africa, [2] are similar to the SANS 164-1 connectors, but have the earth pin flattened on one side to prevent conventional plugs from being inserted into dedicated sockets ...
BS 546, Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50–60 Hz) circuits up to 250 V is an older British Standard for three-pin AC power plugs and sockets: four sizes with current capacities from 2 A to 30 A. Originally published in April 1934, it was updated by a 1950 edition which is still current, [1 ...
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 ...
Older sockets are so shallow that it is possible to touch the pins of a plug when the plug is inserted only deep enough to get electrical power on the pins, while newer sockets are deep enough to protect from this kind of accident. CEE 7/1 sockets accept CEE 7/4, CEE 7/6 and CEE 7/7 plugs without providing an earth connection.
Crabtree's catalyst, a complex of iridium with 1,5-cyclooctadiene, tris-cyclohexylphosphine and pyridine; Crabtree effect, a phenomenon whereby the yeast, Saccharomyces cerevisiae, produces ethanol aerobically in the presence of high external glucose concentrations rather than producing biomass via the tricarboxylic acid cycle
Apple is ditching its in-house iPhone charging plug and falling in line with the rest of the tech industry by adopting a more widely used connection standard. A big part of the reason is a ...
The yellow P+N+E, 4h (120°) plug is a single phase connector that is in widespread use on the British Isles for 110 V building site and fairground applications. A popular model of this socket type is marketed under the brand name MK Commando [12] which leads some users to refer to all IEC 60309 sockets by the generic trademark Commando sockets.
A variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A.
