EXAM QUESTIONS - SET 1
1. Safe Isolation

While preparing to replace a socket outlet in a commercial office, the
electrician switches off the circuit at the consumer unit. What is the next step
to ensure safe isolation?

 A. Remove the socket faceplate
 B. Lock off the circuit breaker and place a warning tag
 C. Test insulation resistance
 D. Check the earthing arrangement

,✅ Correct Answer: B. Lock off the circuit breaker and place a warning
tag
Explanation: Safe isolation requires securing the isolator against re-
energization. Lock-off and tagging are mandatory before conducting a live-
dead-live test sequence.


2. Tools for Isolation

A trainee asks which instrument is best for confirming dead before working.
What should the supervising electrician recommend?

 A. Multimeter
 B. Approved voltage indicator with proving unit
 C. Clamp meter
 D. Continuity tester

✅ Correct Answer: B. Approved voltage indicator with proving unit
Explanation: GS38 requires a dedicated voltage indicator. Multimeters and
clamp meters are not approved because they can give misleading results and
are not designed for safe isolation checks.


3. Initial Verification

During initial verification of a new lighting circuit, the electrician measures
insulation resistance of 0.95 MΩ between live and earth. What should be
done?

 A. Accept the result as compliant
 B. Record the result but energize anyway
 C. Investigate and locate the fault before energization
 D. Replace the MCB

✅ Correct Answer: C. Investigate and locate the fault before
energization
Explanation: Minimum insulation resistance per BS 7671 is 1.0 MΩ for

, most circuits. A lower reading may indicate damaged cable, moisture ingress,
or faulty accessories.


4. Periodic Inspection

A landlord requests a report on the condition of wiring in a rental property.
Which document should be issued after inspection and testing?

 A. EIC
 B. MEIWC
 C. EICR
 D. Schedule of Test Results only

✅ Correct Answer: C. EICR
Explanation: A Periodic Inspection leads to an Electrical Installation
Condition Report (EICR), which records condition codes (C1, C2, C3, FI).


5. Documentation

Which certificate is appropriate for adding an extra socket outlet to an
existing ring final circuit?

 A. EIC
 B. MEIWC
 C. EICR
 D. Test Schedule

✅ Correct Answer: B. MEIWC
Explanation: Minor alterations and additions, such as adding a socket,
require a Minor Electrical Installation Works Certificate (MEIWC), not a
full EIC.
