Q275ModerateIS Codes & IE Rules

As per IS 732, a leakage current in an installation should not exceed __________ of the full load current.

Answer & step-by-step solution
Correct answer: C. 1/5000th
Quick explanation

Under the IS 732 rule referenced by the paper, installation leakage current should not exceed 1/5000 of the full-load current. Limiting leakage is important for shock protection, insulation health and avoiding unwanted protective-device operation.

Ileak,max = Ifull-load / 5000

Concept & Reasoning

Leakage current is current flowing through insulation/protective paths under normal conditions. The acceptable limit is small compared with load current. For this historical code-based MCQ, use the specified fractional limit exactly as tested.

How to Solve It in the Exam

Leakage limit is a very small fraction: 1/5000 in this question.

Important Exam Point

Standards can be edition-specific; preserve the exam's referenced code context.

Quick Trick

Leakage limit is a very small fraction: 1/5000 in this question.

Common Mistake

Choosing 1/100 simply because it is easier to remember; that would be far too large.
