The 3-pin socket connection diagram shows how to safely wire Live, Neutral, and Earth wires to a socket outlet. It ensures safe operation of appliances by providing a return path and grounding. Proper connection prevents electric shocks and short circuits.
Formula & Table Summary:
Basic Wiring Concept:
Live → Right Pin | Neutral → Left Pin | Earth → Top Pin
| Pin Name | Wire Color (Standard) | Function |
|---|---|---|
| Live (L) | Red / Brown | Carries current to the appliance |

3 pin socket wiring diagram
A 3-pin socket is commonly used to power electrical appliances that require grounding for safety. It has three terminals: Live (L), Neutral (N), and Earth (E). The live wire carries current to the appliance, the neutral wire completes the circuit, and the earth wire provides a path to ground in case of leakage. The earth pin is slightly longer and thicker, ensuring it's the first to connect for safety. This socket is standard in most household and office outlets for devices like refrigerators, computers, and ovens.
