2. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A small circuit breaker typically has a manual control lever to switch the circuit off or reset a tripped breaker, while a larger unit may use a solenoid to trip the mechanism, and an electric motor to restore energy to springs (which rapidly separate contacts when the breaker is tripped).

3. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.

4. Fuse (electrical) - Wikipedia

   en.wikipedia.org/wiki/Fuse_(electrical)

   However, any such breaker sold today does have one flaw. It may be installed in a circuit-breaker box with a door. If so, if the door is closed, the door may hold down the breaker's reset button. While in this state, the breaker is effectively useless: it does not provide any overcurrent protection. [16]

5. High-voltage switchgear - Wikipedia

   en.wikipedia.org/wiki/High-voltage_switchgear

   Circuit breakers are essential elements of high-voltage power systems because they are the only means to safely interrupt a short circuit current. The international standard IEC 62271-100 defines the demands linked to the characteristics of a high voltage circuit breaker. [7] The circuit breaker can be equipped with electronic devices to know ...

6. Resettable fuse - Wikipedia

   en.wikipedia.org/wiki/Resettable_fuse

   The resetting will often not take place even if the fault alone has been removed with the power still flowing as the operating current may be above the holding current of the PPTC. The device may not return to its original resistance value; it will most likely stabilize at a significantly higher resistance (up to 4 times initial value).

7. Power strip - Wikipedia

   en.wikipedia.org/wiki/Power_strip

   These power strips have a reset button for the circuit breaker, which is used to return the strip to service after an overload has caused it to trip. On some power strips, the red, lighted rocker switch actually controls a thermal circuit breaker which flips to off when tripped. Resetting is done by flipping the switch back on. [11] [12]

9. Electrical fault - Wikipedia

   en.wikipedia.org/wiki/Electrical_fault

   An asymmetric or unbalanced fault does not affect each of the phases equally. Common types of asymmetric fault, and their causes: line-to-line fault - a short circuit between lines, caused by ionization of air, or when lines come into physical contact, for example due to a broken insulator. In transmission line faults, roughly 5% - 10% are ...
