Gfci Outlet Schematic

Gfci also known as ground fault circuit interrupter is a protective device which automatically detects the ground faults and leakage current and provides personal protection against electrocution.

Gfci outlet schematic. The gfci has an internal breaker that trips and stops the power supply to the outlet if the circuit is shorted or overloaded thus protecting the house from electrical hazards. The gfci is integrated into an electrical outlet and it typically has a red or possibly white reset button on the outlet s faceplate. The current flow through the primary and secondary windings of t the top of the diagram will either be 0 if t. If the receptacle senses any sort of an electrical overload or imbalance it is designed to trip the circuit in a fraction of a second.

In the second wiring diagram the lamp is connected directly to the line terminals of gfci i e. In the gfci mainly two wires connect as also shown in a diagram the current flowing from the source and coming back are some due to current laws. The line set carries the incoming power and the load set distributes the power among additional outlets while also providing shock protection. Connect the power wire black to the line set and the white wire to the load set on the gfci outlet.

Gfci outlet requirements mandate that line terminals identified by color require the white line conductor neutral to connect to the silver line terminal and the black line conductor hot to connect to the brass line terminal. The gfci outlet consists of 2 sets of wires marked as line and load. Gfci outlet wiring diagram. Injury may still occur in some cases for example if a human falls after receiving a shock or if the person touches both conductors at the same time which an rcd won t.

If the gfci outlet won t rest it could indicate a number of things such as. Gfci as an outlet receptacle combo or circuit breaker automatically cuts off the main power supply within millisecond against electric shock. Direct main power supply. The outlet monitors how much energy is going into it when in use.

So gfci designed as checking the difference between the current leaving and returning through current transformer of the gfci to protect device exceeds 5ma. A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. Wiring a gfci combo switch outlet with a light bulb in the first wiring diagram the connected load as light bulb is gfci protected as it is control by the combo switch and connected to the load terminals of gfci.
