Sample questions
01What is the purpose of a protective conductor continuity test?
- A.To confirm the protective device will trip within 0.4 seconds
- B.To measure the prospective fault current at the origin
- C.To verify the integrity of the protective conductor
- D.To verify insulation between live conductors and earth
Why: Protective conductor continuity testing verifies that the protective conductor provides a continuous low resistance path.
02What is the maximum permissible resistance for the R1+R2 measurement on a ring final circuit?
- A.A fixed maximum of 1 ohm for all ring circuits
- B.No more than 0.05 ohms in every case
- C.Exactly half of the measured Ze value
- D.The calculated design value
Why: R1+R2 should not exceed the calculated design value based on cable length and CSA.
03What test current is typically used for continuity testing?
- A.At least 200mA
- B.Any current
- C.Exactly 1A
- D.Less than 10mA
Why: Continuity testing should use a test current of at least 200mA to ensure good contact and accurate readings.
