| | Domestic AC power plugs & sockets - Wikipedia, the free encyclopedia |
 | | A power socket (electrical socket, power point, mains socket, plug-in, outlet, receptacle, or female power connector) is a connection point that delivers mains electricity when a plug is inserted into it. |
 | | Above 10 amps, equipment must be either wired permanently to the electrical supply system with appropriate branch circuit protection or connected to the mains with an appropriate high power industrial connector. |
 | | Voltages and frequencies may vary greatly, with different contractors installing different systems at different times. |
