2. 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, 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 ...

   A circuit breaker is an electrical safety device ... High-voltage circuit breakers used on transmission systems may be arranged to allow a single pole of a three ...

4. Distribution board - Wikipedia

   en.wikipedia.org/wiki/Distribution_board

   A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

5. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   Single-pole circuit breakers feed 120 V circuits from one of the 120 V buses within the panel, or two-pole circuit breakers feed 240-volt circuits from both buses. 120 V circuits are the most common, and used to power NEMA 1 and NEMA 5 outlets, and most residential and light commercial direct-wired lighting circuits.

6. Recloser - Wikipedia

   en.wikipedia.org/wiki/Recloser

   Single Wire Earth Return Network Protection: SWER network design topology is discouraged in modern electrical engineering due to safety reasons, but due to cost savings it is sometimes deployed. Single Phase Reclosers can be used to improve safety on these lines during fault events. Single Phase Recloser Single Phase Laterals Overcurrent Protection
