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 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.

3. Earth-leakage circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Earth-leakage_circuit_breaker

   To eliminate this confusion, the IEC decided to apply the term residual current device (RCD) to differential-current-operated ELCBs. Residual current refers to any residue when comparing current in the outbound and return currents in the circuit. In a single phase circuit this is simply the live or phase current minus the neutral current. In a ...

4. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   Separate circuit breakers must never be used for live and neutral, because if the neutral is disconnected while the live conductor stays connected, a very dangerous condition arises: the circuit appears de-energized (appliances don't work), but wires remain live and some residual-current devices (RCDs) may not trip if someone touches the live ...

   (Outside North America these are referred to as a "Residual-current device" or RCD.) Arc-Fault Circuit Interrupter (AFCI) protection is required to protect nearly all finished areas of a home with the exception of bathrooms. This device, which can be a circuit breaker or the first outlet on a circuit, is designed to detect hazardous electrical ...

7. 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.
