A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
Outlet Wiring Diagrams. The outlet addition methods we show here are based on the most common wiring 14 gauge wire on a 15 amp circuit and an 18 cu in. In the diagram below a 2 wire nm cable supplies line voltage from the electrical panel to the first receptacle outlet box. This diagram shows the wiring for multiple receptacles in an arrangement that connects each individually to the source.

Diagrams shown on this page are simplified for clarity. This is a polarized device. 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. This circuit diagram shows the wiring for a new receptacle outlet connected at an existing light fixture where the source hot is at the ceiling box.
This repeats until the end of the chain.
All wires are spliced to a pigtail which is connected to each device separate from all the others in the row. To wire multiple outlets follow the circuit diagrams posted in this article. The long slot on the left is the neutral contact and the short slot is the hot contact. Electrical outlet boxes can have numerous nm cables going in and out. The wiring diagram above shows how switched outlets are often wired.
Outlet Wiring Diagrams. The following wiring diagrams show that multiple outlets are wired to a single pole spst switch one way or two way in us switch. See actual switch box wiring diagram.
