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 321-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 — 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.
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.
