Socket-outlet, auto switched by plug insertion. Automatically switched socket-outlets such as these may be used to supply power to refrigerators, some computers and other accessories that normally should not be switched off. The absence of a user operable switch prevents the accidental switching off of such devices Surface socket-outlet and plug.
At the same time, they are switched off (but are designed to draw some power) or in standby mode. It only occurs because some devices claim to be "switched off" on the electronic interface but are in a different state. Switching off the plug or disconnecting it from the power point can completely solve the problem of standby power.

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 ...
A switch is a device capable of safely disconnecting the supply even if devices in the installation were drawing the full maximum load the installation was rated for. An isolator is not, it should only be used when the installation is drawing no power, i.e. the main switch in the consumer unit is off. When a supply is switched off under load ...
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
Although the standard does not permit extension cables and does not define any socket-outlets, unauthorized extension cables and sockets are manufactured. UK shaver sockets are designed to accept BS 4573 shaver plugs while also accepting Europlugs. In this configuration, the connection supply is only rated at 200 mA.
A receptacle tester being used to check for some types of improper wiring of an outlet. For this particular tester, proper wiring is indicated by the two yellow lights. The outlet tester checks that each contact in the outlet appears to be connected to the correct wire in the building's electrical wiring. It can identify several common wiring ...
