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. Arc-fault circuit interrupter - Wikipedia

   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   This AFCI (the circuit breaker with the yellow label) is an older generation AFCI circuit breaker. The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter ( AFCI ) or arc-fault detection device ( AFDD ) [ 1 ] is a circuit breaker that breaks the circuit when it detects the electric arcs that are ...

   Receptacles protected in this manner or with a GFCI circuit breaker should be labeled "GFCI protected". (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 ...

   One GFCI receptacle can serve as protection for several downstream conventional receptacles. GFCI devices come in many configurations including circuit-breakers, portable devices and receptacles. Another safety device introduced with the 1999 code is the arc-fault circuit interrupter (AFCI). This device detects arcs from hot to neutral that can ...

6. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   In the US, where split-phase supplies are common, in a branch circuit with more than one live conductor, each live conductor must be protected by a breaker pole. To ensure that all live conductors are interrupted when any pole trips, a common-trip set of breakers must be used. These may either contain two or three tripping mechanisms within one ...
