Sample questions
01What is the correct sequence for initial verification tests?
- AContinuity of protective conductors, insulation resistance, polarity, Zs, RCD
- BInsulation resistance, continuity, RCD, polarity, Zs
- CRCD operation, Zs, polarity, continuity, insulation resistance
- DZs, RCD operation, polarity, insulation resistance, continuity
Why: The sequence per GN3: continuity of protective/bonding conductors, ring continuity, insulation resistance, polarity, Zs, functional tests (RCDs).
02What instrument is used for testing continuity of protective conductors?
- ARCD tester
- BEarth fault loop impedance tester
- CInsulation resistance tester
- DLow resistance ohmmeter
Why: A low resistance ohmmeter (typically producing 200mA minimum at 4-24V DC) is used for continuity testing.
03What test voltage is used for insulation resistance testing on 230V circuits?
- A1000V DC
- B500V DC
- C230V AC
- D250V DC
Why: For circuits up to 500V, including standard 230V circuits, insulation resistance is tested at 500V DC.
Common questions
Is the BS7671 Inspection & Testing mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
