  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.

    Ground-fault circuit interrupter (GFCI) protection is required on receptacles in wet locations and locations where there exists an easy path for fault current to travel to earth. This includes all receptacles intended to service kitchen counter surfaces, crawl spaces at or below grade level, basements, garages and accessory buildings, bathrooms ...

  4. Circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Circuit_breaker

    A thermal–magnetic circuit breaker, which is the type found in most distribution boards in Europe and countries with a similar wiring arrangement, incorporates both techniques with the electromagnet responding instantaneously to large surges in current (such as short circuits) and the bimetallic strip responding to lesser but longer-term over ...

  5. Arc-fault circuit interrupter - Wikipedia

    en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

    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 a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires.

    For internal references, some lengthy articles are further broken into "parts" with Roman-numerals (parts I, II, III, etc.). Each code article is numbered based on the chapter it is in. Those wiring methods acceptable by the NEC are found in chapter 3, thus all approved wiring method code articles are in the 300s.

  7. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

    How is the difference in the currents calculated. If we have a resistor and some simple electrical circuit the current is maximum in the input (something like 220 volts / 16 ampers) but when it gets to the circuit it is lowered to lets say 1 amper (16 ohms resistance) and on the neutral wire we get a maximum of 1 amper current.
