IS 3043 is the Indian Standard code of practice for earthing. It covers principles and practices for system earthing and protective/equipment earthing, including electrode arrangements and safety considerations.
Formula / Key Relation
IS 3043 → Earthing
IS 732 → Electrical wiring installations
Detailed Explanation
Concept & Reasoning
Earthing provides a controlled low-impedance path for fault current and helps exposed conductive parts remain at safer touch potentials. IS 732 relates to electrical wiring installations, so it is a common distractor in standards questions.
How to Solve It in the Exam
3043 = earthing; 732 = wiring.
Important Exam Point
Learn standard numbers as concept pairs rather than isolated digits.
Related Revision Path

Quick Trick
3043 = earthing; 732 = wiring.
Common Mistake
Confusing IS 3043 with IS 732.
Exam Tip
Learn standard numbers as concept pairs rather than isolated digits.
