If wall receptacle circuits operated like that, you wouldn't be able to plug an appliance in down stream from another appliance in the same circuit because the voltage wouldn't be sufficient to run it. Here one ground fault circuit interrupter protects multiple duplex receptacles coming after it, known as multiple-location protection.
The load itself conducts current down the line to the subsequent loads in the circuit. Find a detailed explanation of how to count conductors here.
Wiring outlets together using the device terminals, instead of a pigtail splice as shown in the next diagram, can create a weakest link problem.
This wiring is commonly used in a 20 amp kitchen circuit where two appliance feeds are needed, such as for a refrigerator and a microwave in the same location.
While wires are conductors, they aren't the only ones in an electrical box.
This wiring allows for source voltage at each outlet independent of the others in the circuit. Wiring Diagram for Multiple Outlets This diagram shows the wiring for multiple receptacles in an arrangement that connects each individually to the source. By contrast, switches and circuit breakers are wired in series.
This keeps each duplex receptacle connected directly to the gfci. Devices like switches and receptacles are also considered conductors, and they add to the total present in the box.
Home Page. All wires are spliced with a pigtail at the devices to pass current to the next. Using this method, any break or malfunction at one outlet will likely cause all the outlets that follow to fail as well. Calculate total conductors allowed in a box before adding new wiring, etc. Wiring a GFCI to Protect Multiple Outlets Here one ground fault circuit interrupter protects multiple duplex receptacles coming after it, known as multiple-location protection.
In this diagram wall outlets are wired in a row using the terminal screws to pass voltage from one receptacle to the next.
Wiring Diagram for Multiple GFCI's In this diagram multiple ground fault circuit interrupter receptacles are wired together using pigtails to connect the source. By code there is a limit to the number of conductors allowed inside an electrical box depending on the wire gauge you're using and the size of the box.
Two-wire cable runs from the gfci to all the following outlets. In a series circuit, current must pass through a load at each device. In this diagram multiple ground fault circuit interrupter receptacles are wired together using pigtails to connect the source. This page contains several diagrams for 2 or more receptacle outlets in one circuit.
