Belkin also sells wall chargers, car chargers, charging stations, power banks, surge protectors, power strips, and wireless chargers for smartphones, tablets, smartwatches, laptops, computers, and other electronic devices. In 2016, Belkin released an iPhone-compatible adapter for simultaneous iPhone charging and headphone use. [29]
A North American power strip with two USB power ports that includes a built in surge protector. A power strip (also known as a multi-socket, power board and many other variations [a]) is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket.
Power strips are handy, but they’re only designed for short-term use with low-power items like your charger, not microwaves and freezers. Power strips are handy, but they’re only designed for ...
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 ...
In that case, circuit protection devices may detect a fault to a grounded metal enclosure and automatically de-energize the circuit, or may provide a warning of a ground fault. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures.
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations by the normal current flow in the power system. Contact voltage is a better defined term when large voltage appear as a result ...
In the past, grounded appliances have been designed with internal isolation to a degree that allowed the simple disconnection of ground by cheater plugs without apparent problem (a dangerous practice, since the safety of the resulting floating equipment relies on the insulation in its power transformer).
The normal technical term (in both British and International English) for an AC power socket is socket-outlet, [4] but in non-technical common use a number of other terms are used. In British English the general term is socket, but there are numerous common alternatives, including power point, [5] plug socket, [6] wall socket, [7] and wall plug ...
