When working with electrical wiring at home, safety starts with knowing what each wire color means. Color codes are used worldwide to make wiring easier and safer to identify. Here’s a quick guide to help you understand the basics.
Why Do Wiring Colors Matter?
- Prevents mistakes during installation or repair.
- Helps identify live, neutral, and earth wires quickly.
- Ensures compliance with electrical safety standards.
Common Wiring Color Codes in India (and Many Other Regions)
1.Live (Phase) Wire – Red / Brown
- Carries current from the power source to appliances.
- Handle with caution as it is always “live.”
2.Neutral Wire – Black / Blue
- Completes the circuit by carrying current back.
- Usually safe to touch once disconnected, but never assume.
3.Earth (Ground) Wire – Green or Green-Yellow
- Provides a safety path for stray current.
- Protects you from electric shocks.
Understanding wiring color codes is a simple but essential step toward safe electrical work at home. Whether you’re fixing a switch or adding a new appliance, knowing what each wire means helps you stay safe and avoid costly mistakes.
