NET / JIB

The AM2/AM2S is the end-point assessment electricians must pass to confirm occupational competence, administered by NET (National Electrotechnical Training) with the JIB and delivered at approved assessment centres. It is PREDOMINANTLY PRACTICAL — safe isolation and risk assessment, composite single- and three-phase installation, inspection, testing and certification to BS 7671, and fault diagnosis and rectification — with about 16 to 19 hours of assessed section time. It also includes Section E, an online applied-knowledge test of 30 multiple-choice questions (45 in AM2S v1, for apprentices registered from September 2023) on health and safety, Building Regulations (Part P) and BS 7671. It is NOT a written-only MCQ exam. This free prep includes 137 research-based practice questions with explanations and an AI tutor, targeting the Section E applied-knowledge test and the underpinning theory needed across the practical sections.

Sample AM2 / AM2S Practice Questions

Try these sample questions to review concepts for the AM2 / AM2S exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 137+ question experience with AI tutoring.

1When carrying out safe isolation, what must you do FIRST with your voltage indicator before you use it to prove a circuit dead?

A.Connect it across the circuit you intend to isolate first

B.Prove it on a known live source or proving unit

C.Lock off the main switch and apply a warning label

D.Record the readings on the inspection schedule

Explanation: The correct safe isolation sequence requires you to prove your voltage indicator gives a positive indication on a known live supply or proving unit BEFORE you rely on it to prove the circuit dead. This confirms the instrument is working so a 'dead' reading can be trusted.

2A voltage indicator used for safe isolation should comply with which HSE guidance note?

A.GS38

B.HSG85

C.GN3

D.INDG354

Explanation: HSE Guidance Note GS38 covers the requirements for test equipment used by electricians, including voltage indicators. It specifies fused probes with a maximum 4 mm (ideally 2 mm) exposed tip, finger guards and insulated leads.

3According to GS38, what is the recommended maximum exposed metal tip length on a voltage indicator probe?

A.10 mm

B.4 mm

C.20 mm

D.25 mm

Explanation: GS38 recommends test probes have no more than 4 mm of exposed metal tip, and ideally 2 mm or spring-loaded shrouds, to minimise the risk of shorting between adjacent terminals and reduce arc-flash hazard.

4During safe isolation of a single-phase final circuit, between which points must you test to confirm the circuit is dead?

A.Line to neutral only (single pair test)

B.Line to earth only (single pair test)

C.Line-neutral, line-earth and neutral-earth

D.Neutral to earth only (single pair test)

Explanation: To prove a single-phase circuit dead you must test all combinations: line to neutral, line to earth and neutral to earth. Testing only one pair could miss a borrowed neutral or a fault that leaves one conductor live.

5What is the primary purpose of applying a padlock and unique key to an isolated main switch during work?

A.To comply with the manufacturer's warranty terms

B.To stop others re-energising the circuit during work

C.To stop the RCD from tripping nuisance trips

D.To earth the installation safely

Explanation: Locking off with a padlock to which only the person working holds the key prevents anyone else from inadvertently re-energising the circuit while work is in progress. A warning notice is also applied so the reason for isolation is clear.

6After proving a circuit dead with your voltage indicator, what should you do next to validate the result?

A.Begin work immediately to save time

B.Re-prove the indicator on the known live source

C.Replace the voltage indicator batteries

D.Remove the lock-off device

Explanation: After confirming the circuit is dead you must re-prove the voltage indicator on the same known live source. A positive indication confirms the instrument was working throughout, so the 'dead' reading is genuine and not caused by a failed tester.

7Which legislation places a duty on electricians to ensure conductors are made dead and kept dead while work is carried out, where reasonably practicable?

A.The Building Act 1984

B.The Electricity at Work Regulations 1989

C.The Health and Safety (Display Screen Equipment) Regulations

D.The Construction Products Regulations

Explanation: The Electricity at Work Regulations 1989, particularly Regulation 14, require that work on or near live conductors is avoided unless it is unreasonable for them to be dead and suitable precautions are taken. This underpins the safe isolation procedure.

8Under RIDDOR, which of the following must an employer report to the HSE?

A.A minor cut treated with a plaster on site

B.An electric shock causing unconsciousness (specified injury)

C.A near-miss that caused no injury or damage

D.An employee taking a single day off for a cold

Explanation: RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) requires reporting of specified injuries, which include any injury caused by electric shock leading to unconsciousness, resuscitation or admittance to hospital for more than 24 hours.

9What is the correct first step in a risk assessment before starting work in the AM2 installation area?

A.Select the cable for the circuit

B.Identify the hazards present in the work area

C.Energise the test rig

D.Complete the electrical installation certificate

Explanation: A risk assessment begins with identifying the hazards present. You then decide who might be harmed, evaluate the risks and decide on control measures, record the findings and review them. In the AM2 you must demonstrate this systematic approach before working.

10In the hierarchy of control, which measure should always be considered FIRST?

A.Personal protective equipment

B.Eliminating the hazard

C.Administrative controls such as signage

D.Providing training

Explanation: The hierarchy of control places elimination of the hazard at the top, followed by substitution, engineering controls, administrative controls and finally PPE. Removing the hazard entirely is the most effective control; PPE is the last resort.

About the AM2 / AM2S Exam

The AM2 (and its current versions AM2S and AM2E) is the industry end-point assessment that qualifying electricians in England, Wales and Northern Ireland must pass to confirm occupational competence. It is predominantly a practical assessment of safe isolation, composite installation, inspection and testing, and fault diagnosis, with an online applied-knowledge multiple-choice test (Section E) on health and safety, Building Regulations and BS 7671.

AM2 / AM2S: Suggested Study Strategy

1Learn the safe isolation sequence cold: prove the tester live, isolate and lock off, prove the circuit dead in all combinations, then re-prove the tester live

2Memorise the BS 7671 Part 6 test sequence — continuity, ring final continuity, insulation resistance, polarity, then live tests (Ze/Zs, PFC, RCD, functional)

3Know the key numbers: 1 MΩ minimum insulation resistance at 500 V DC, 0.4 s disconnection for TN final circuits, 30 mA RCD tripping within 40 ms at 5x and not at 0.5x

4Be confident with Zs = Ze + (R1 + R2) and the 3%/5% voltage-drop limits for lighting and other circuits

5Revise Part P notifiable work, special-location/bathroom zones and the harmonised conductor colours (brown/blue, brown-black-grey three-phase)

Frequently Asked Questions

Is the AM2 a written exam or a practical assessment?

The AM2/AM2S is predominantly a PRACTICAL end-point assessment with about 16 to 19 hours of assessed section time, covering safe isolation, composite installation, inspection and testing, and fault diagnosis. It includes one online applied-knowledge test (Section E) of 30 multiple-choice questions (45 in AM2S v1), but it is not a written-only exam.

How many multiple-choice questions are in the AM2 Section E online test?

Section E, the Assessment of Applied Knowledge, is an online test of 30 multiple-choice questions in 1 hour for AM2 and AM2S, covering health and safety, Building Regulations and BS 7671. In AM2S v1 it has 45 questions in 1.5 hours and also covers inspection and testing, installation practices, fault diagnosis, design and planning, and behaviours. Our 137 practice questions target this test plus the underpinning theory across the practical sections.

What is the difference between AM2, AM2S and AM2E?

AM2 is for learners on the Level 3 NVQ (City & Guilds 2357 or EAL 1605). AM2S is for Installation & Maintenance Electrician apprentices who started before September 2023, and AM2S v1 for those registered from September 2023; AM2E is the Experienced Worker route. NET says there is little difference in content within the group, apart from the AM2 excluding containment, while AM2S v1's Section E is longer (45 questions in 1.5 hours).

How much does the AM2 cost in 2026?

NET's recommended first-attempt prices are £885 for AM2, £965 for AM2S and £1,340 for AM2S v1, usually paid through your training centre. Single-section re-sits from 1 April 2026 to 31 March 2027 cost £190-£320 depending on the version and section, with higher fees for re-sitting several composite installation sections.

How long does the AM2 take?

NET's section times add up to 16 hours 15 minutes for the AM2, 17 hours 45 minutes for the AM2S and 19 hours for the AM2S v1, plus reading and preparation time before each section, at an NET-approved assessment centre. The Section E online applied-knowledge test takes 1 hour (1.5 hours in AM2S v1).

Is this free AM2 practice as good as paid prep?
