These are real pages from the book. The table of contents is the full one: 9 parts and 64 topics.
You're on the practical, standing at the consumer unit, and the assessor asks what you do first. Your hand is already reaching for the tester.
The guide does say inspection comes before testing. But it says it in paragraphs, between regulation numbers and footnotes, so you nod, turn the page and the order doesn't stay.
In this book that topic is one page: the installation drawn disconnected, inspection marked as step one, and the Schedule of Inspections drawn as your checklist, box by box.
Safe isolation, the dead tests in order, the live test sequence, maximum Zs and EICR coding: each one gets its own page, drawn the same way.
You know what comes first, why it comes first and what to tick, and you do it without going back to the guide.
Before the tester, safe isolation, inspection, dead tests, live tests, maximum Zs, certificates and schedules, EICR coding and revision for the practical and the written exam: 68 pages, all illustrated.
Think of it this way:
You're doing R1+R2 on a radial with the assessor watching. You need the link in the right place and a reading you can trust.
You open the R1+R2 page and the circuit is drawn: line and cpc linked at the board, the probes at the far end, and where the reading goes on the schedule.
Same with the ring final end-to-end, insulation resistance minimums, maximum Zs and the 80% rule, RCD testing and C2 versus C3: each one on its own page.
Inspection & Testing Illustrated is 68 pages in 9 parts, every topic drawn, and it ends with a revision part for the practical and the written exam.
What you see drawn, you don't have to memorize.
Initial verification vs periodic inspection, what the 2391 asks of you, your documents, the multifunction tester, GS38 leads, calibration and earthing systems.
Why it comes first, the isolation sequence step by step, prove–test–prove, every dead combination, locking off and isolating for Ze and bonding.
Why inspection comes first, the origin, earthing and main bonding, cable routes and zones, bathrooms, and what you check by eye on RCDs, AFDDs and SPDs.
The dead test sequence, bonding continuity, R1+R2 and R2, the ring final in 3 steps, insulation resistance, polarity and the TT earth electrode: so you never clip on for insulation before continuity.
The live sequence, Ze, Zs, PSCC and PEFC, RCD testing and tester set-up, functional testing, phase sequence and voltage drop.
The disconnection chain, disconnection times, the maximum Zs tables, the 80% rule, Type B, C and D, and what to check when Zs is too high: so a reading on the tester becomes a pass or a fail you can explain.
EIC, Minor Works or EICR, the Schedule of Circuit Details, the Schedule of Test Results, supply characteristics and signatures.
Recommended intervals, extent and limitations, the four codes, C1, C2, C3, FI, and satisfactory or unsatisfactory.
The full sequence on one page, key numbers, ring readings that don't add up, Zs worked corrections, what's most asked and a practical day checklist.
At the end of the book: A revision part with the full sequence on one page, key numbers, Zs worked corrections and a practical day checklist.
Practise with exam-style questions on every test, Zs calculation and coding, each answer explained with a drawing, so you know where you stand before the real thing.
The errors electricians make most often on the practical and on the schedules, each one shown before and after, so you can spot them before an assessor does.

Yes. It doesn't teach you to wire: it starts from safe isolation and takes you through every test, the schedules and EICR coding, in the order you'll use them. It follows the UK route (BS 7671, GN3 and the 2391). If you're doing the 2394 and 2395 separately, the initial verification parts match the 2394 and the periodic inspection and EICR parts match the 2395.
From BS 7671 (current edition and amendment), IET Guidance Note 3, the IET On-Site Guide, HSE GS38 and the 2391 qualification specification. The maximum Zs values come from the tables of the current amendment. It doesn't replace GN3 or the On-Site Guide: those are for looking things up, this is for learning the order and the numbers, one drawn page at a time.
No. It's an independent study book, not published or endorsed by City & Guilds, the IET or BSI. Always keep the current BS 7671 to hand.
No. It doesn't replace accredited training or supervised practical experience, and it doesn't give you a qualification or certificate. It helps you understand and revise what the course and the practical ask of you.
No. They're exam-style questions written for this book, not official questions from any exam.
As a PDF by email, to the address you enter at checkout. The 2 included books come the same way.
No. It's a one-off payment.
It's a PDF you can print, all of it or just the pages you want for the van or the tester case.
