What is a 4 Prong Outlet Wiring Diagram and How is it Used
A 4 Prong Outlet Wiring Diagram specifically illustrates the connections for a NEMA 14-30 or NEMA 14-50 receptacle. Unlike older 3-prong outlets, these 4-prong configurations are designed to handle the significant power demands of appliances like electric dryers and ranges. The "4 prong" refers to the four distinct terminals on the outlet itself, each serving a specific purpose in delivering electricity. The primary function of a 4 Prong Outlet Wiring Diagram is to ensure the safe and efficient flow of power. It details how the incoming wires from your electrical panel should be connected to the outlet. These wires typically include:- Hot Wire 1 (usually black)
- Hot Wire 2 (usually red)
- Neutral Wire (usually white)
- Ground Wire (usually green or bare copper)
| Outlet Terminal | Corresponding Wire Color | Function |
|---|---|---|
| L1 (Large slot) | Black (Hot 1) | Provides one source of 120V power |
| L2 (Large slot) | Red (Hot 2) | Provides the second source of 120V power |
| N (T-shaped slot) | White (Neutral) | Carries the return current |
| G (Round or U-shaped slot) | Green or Bare Copper (Ground) | Safety connection to the earth |
