In a domestic three-wire system, which wire provides the safety connection to earth?

1. Indian domestic supply uses three wires: live, neutral, and earth. 2. The live wire is at high potential; the neutral wire returns the current. 3. The earth wire is connected to the metal body of appliances. 4. If a fault makes the body live, current flows safely to earth. 5. The earth wire is colour-coded green in standard wiring. 6. So the green earth wire provides the safety connection. _Source: syllabus Science Ch 13 'Magnetic Effects of Electric Current' (learncbse.in extract)_
