2391 Inspection & Testing Pro

Pass the City & Guilds 2391-52 with 556 exam-standard questions, real exam-format mock tests, and the field tools you will actually use on site.

Built against BS 7671:2018+A4:2026 Part 6 (Inspection and Testing).

EXAM PREP — OPEN BOOK & CLOSED BOOK The 2391-52 is sat in two parts, so the question bank is organised the same way. Work through the full open-book syllabus, then switch to Closed Book to drill the topics you must know without the regs in front of you.

• Initial Verification — 132 questions • Periodic Inspection — 133 questions • Test Procedures — 78 questions • Certification and Reporting — 63 questions • Fault Coding — 67 questions • Safe Isolation and GS38 — 47 questions • Statutory Requirements — 36 questions

Every question carries a worked explanation, and diagrams are drawn to scale for test sequences, schedules and certificate extracts.

MOCK TEST THAT MATCHES THE REAL THING 60 questions in 120 minutes, weighted across topics exactly as the real 2391-52 paper is. Questions and answer options are shuffled on every attempt, so you learn the subject rather than the position of the right answer.

FOUR ON-SITE CALCULATORS • Max Zs — 0.8 x tabulated rule of thumb • Ring Final — (r1+r2)/4 continuity check • Adiabatic — S = the square root of (I squared x t) / k • Voltage Drop — mV/A/m x Ib x L

QUICK REFERENCE 15 reference cards across test and limiting values, classification and reporting, safe isolation and GS38, and test sequence and procedure. Bookmark the ones you keep coming back to.
