Multiple Receptacle Wiring Diagram

This outlet is commonly used for a heavy load such as a large air conditioner.

Multiple receptacle wiring diagram. Wiring diagram for dual outlets. In the diagram below a 2 wire nm cable supplies line voltage from the electrical panel to the first receptacle outlet box. The socket receptacles are usually marked with signs to indicate the position that each wire should go. This diagram shows the wiring for multiple switched outlets on one switch.

As shown in the fig the switch is firstly installed in the wiring the hot wire from switch feeds all the other parallel connected outlets hence the outlet on off operation can be controlled through the switch. The source for the circuit is at the switch and 2 wire cable runs to each receptacle outlet. This repeats until the end of the chain. 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.

With this wiring both the black and white wires are used to carry 120 volts each and the white wire is wrapped with electrical tape to label it hot. The neutral wire from the circuit is shared by both sets. The outlet should be wired to a dedicated 20 amp 240 volt circuit breaker in the service panel using 12 2 awg cable. At the outlets each is wired using a pigtail splice to make the hot and neutral connections.

For wiring in series the terminal screws are the means for passing voltage from one receptacle to another. Here 3 wire cable is run from a double pole circuit breaker providing an independent 120 volts to two sets of multiple outlets. Wiring a 20 amp 240 volt appliance receptacle.

To wire multiple outlets follow the circuit diagrams posted in this article.
