C&G 2392 Mock Exam — Fundamental Inspection & Testing
Free mock exam for the City & Guilds 2392 (Fundamental Inspection, Testing and Initial Verification). 30 questions drawn from a 370-question bank covering the fundamentals the qualification examines: safe isolation, the dead test sequence in order, continuity of protective conductors, insulation resistance, polarity, earth fault loop impedance, RCD testing, and certification. Every question comes with a worked explanation. Moving on to the full inspection and testing qualification afterwards? Practise with our 2391-50 initial verification and 2391-51 periodic inspection mock exams.

Sample questions
01Which British Standard covers requirements for initial verification and periodic inspection?
- ABS 5839
- BBS 6004
- CBS 7430
- DBS 7671
Why: BS 7671 (IET Wiring Regulations) covers requirements for initial verification and periodic inspection and testing of electrical installations.
02Who is legally qualified to carry out electrical inspection and testing?
- AAnyone holding a current ECS card regardless of qualification
- BOnly an electrician directly employed by the DNO
- CA competent person with appropriate knowledge and experience
- DAny person over 18 who owns approved test equipment
Why: Inspection and testing must be carried out by a competent person with the appropriate knowledge, skills, and experience.
03What is the recommended inspection interval for industrial installations?
- A1 year
- B5 years
- C10 years
- D3 years
Why: Industrial installations typically require inspection every 3 years due to the more demanding environment.
Common questions
Is the C&G 2392 mock exam free?
Yes, it is free with 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 as a qualification?
No. This is independent practice material and does not award a qualification, card or certificate. Where a subject has a formal qualification or card, you gain it through an approved provider.
What is the difference between the 2392 and the 2391?
The 2392 is the fundamental, entry-level inspection and testing qualification — it covers initial verification of new work you or your team have just installed. The 2391 series goes further: 2391-50 covers initial verification in more depth, 2391-51 adds periodic inspection and condition reporting on existing installations, and 2391-52 combines both. Many electricians sit the 2392 first as the stepping stone.
Which topics should I focus on for fundamental inspection and testing?
The dead test sequence in the correct order is the core of it: safe isolation, continuity of protective conductors, ring final circuit continuity, insulation resistance, then polarity — followed by the live tests: earth fault loop impedance, prospective fault current and RCD operation. The explanations on every question in this mock walk through the why, not just the answer.
