The colour code in Indian household wiring is: live = red/brown, neutral = black/blue, earth =:
AYellow / green
BWhite
COrange
DGrey
Answer & Solution
Correct answer: A. Yellow / green
1. In India (and Europe): live = red (or brown in new standard); neutral = black (or blue); earth = green (often yellow-and-green striped).
2. Earth wire connects appliance metal body to ground for safety.
3. If insulation fails, fault current flows safely to earth instead of through a person.
