What is a Double Outlet Wiring Diagram and How is it Used?
A Double Outlet Wiring Diagram, often referred to as a duplex receptacle wiring diagram, shows how the two individual outlets on a standard receptacle are connected to the incoming power supply. These diagrams are essential for electricians and homeowners alike, ensuring that power is distributed correctly and safely. They clearly depict the connections for the hot wire (usually black), the neutral wire (usually white), and the ground wire (usually green or bare copper). These diagrams are vital for several reasons. Primarily, they ensure proper electrical function. By following the diagram, you can connect the wires to the correct terminals on the receptacle. A typical duplex receptacle has two sets of slots, one for each outlet. The diagram shows how the incoming wires are branched to feed both sets of slots.- The hot wire connects to the brass-colored screw terminals.
- The neutral wire connects to the silver-colored screw terminals.
- The ground wire connects to the green screw terminal.
| Wire Type | Terminal Color | Purpose |
|---|---|---|
| Hot | Brass | Carries the electrical current from the power source. |
| Neutral | Silver | Completes the electrical circuit, returning current to the source. |
| Ground | Green or Bare | Provides a safety path for electricity in case of a fault. |
