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.
The addition is a 3 ⁄ 16-inch (4.8 mm) diameter round or U-shaped ground pin, 1 ⁄ 8 in (3.2 mm) longer than the power blades (so the device is grounded before the power is connected) and located from them by 1 ⁄ 4 in (6.4 mm) edge-to-edge or 15 ⁄ 32 in (11.9 mm) center-to-center.
Distribution power systems may be solidly grounded, with one circuit conductor directly connected to an earth grounding electrode system. Alternatively, some amount of electrical impedance may be connected between the distribution system and ground, to limit the current that can flow to earth. The impedance may be a resistor, or an inductor (coil).
The safety ground is disconnected by an adaptor (cheater plug) in a power lead in which the ground conductor is deliberately disconnected, or by cutting a ground pin in the power plug. If a fault develops in any line-operated equipment, cable shields and equipment enclosures may become energized, creating an electric shock hazard.
