UNIT 399

AM2 Practical Assessment

What Is The AM2 Practical Assessment?

The AM2 Practical Assessment is the final part / unit that every NVQ Level 3 Electrical candidate must complete in order to gain their qualification and be eligible to apply for their JIB ECS Gold Card.

Successful completion of the AM2 is compulsory for apprentices, adult trainees or upskilling workers who seek to gain the industry recognised qualified status that attainment of the NVQ provides.

Also known as Unit 399, the AM2 is overseen and maintained by the independent body NET (National Electrotechnical Training Organisation) and can be taken at any one of 40+ assessment centres across England, Wales & Northern Ireland.

The assessment comprises of 6 sections taken over a total of 16.5 hours (2.5 days), during which candidates undertake a series of timed tasks in specially equipped booths containing typical electrical installation wiring systems. The exercises include installation, inspection and testing and fault-finding, and the work must comply with the current British Standard (BS7671: 2015) and meet with the requirements of relevant Health & Safety legislation and industry best practice.

The purpose of the AM2 is to ensure that all qualifying installation electricians achieve a single standard that has been agreed by employers industry-wide as meeting their expectations from newly qualified personnel. The AM2 provides a reliable and trusted independent assessment of safe, high-quality standards for the electrical installation industry, and is deemed as essential by the majority of employers who recognise it as proof of competence for an electrician.

The AM2E & AM2S

The AM2E & AM2S largely follow the same format as the AM2, but with two additional tasks under the Installation section:

  1. Candidate to install a piece of steel conduit with a bend and a set to a box they fix to a set measurement
  2. Candidate to install a piece of PVC conduit between 2 fixed points with a bend and a set over a pre-fixed obstacle.

The candidate then has to wire circuits through these pieces of conduit. An extra 1.5 hrs is allowed to complete these tasks (10 hrs v 8.5 hrs for the AM2).

  • The AM2S ASSESSMENT is taken by apprentices on the NVQ 5357. You may also hear it referred to as the ‘End Point Assessment’ (EPA).

You can find out more about the AM2S Assessment – including its differences with the AM2 – here at the NET website.

Introduction

The AM2 Electrotechnical Assessment of Occupational Competence is designed for those who wish to practise either as an installation electrician, or as a maintenance electrician.

It demonstrates they have the level of competence expected by the industry in the following key occupational areas:

  • Risk assessments and health and safety
  • Safe isolation
  • The interpretation of specifications, drawings and diagrams
  • Planning and preparing to install, terminate and connect identified wiring systems
  • Installing, terminating and connecting identified wiring systems
  • Inspection, testing and certification
  • Fault diagnosis and correction of electrical faults
  • The understanding and application of industry recognised procedures, working practices and the requirements of statutory and non-statutory regulations.

Candidates will be expected to install, terminate, connect, inspect, test, commission and diagnose faults in accordance with the installation specification and the relevant statutory and non-statutory regulations on the following:

  • A three-phase distribution board and sub-circuit
  • A three-phase Direct-on-Line Motor circuit
  • Single-phase lighting and power circuits

The assessment is in six sections:

  • Section A1: Safe Isolation and Risk Assessment
  • Sections A2-A5: Composite Installation
  • Section B: Inspection, Testing and Certification
  • Section C: Safe Isolation of Circuits
  • Section D: Fault Diagnosis and Rectification
  • Section E: Assessment of Applied Knowledge

Section A1: Safe Isolation and Risk Assessment – 45 mins

In this section, you need to demonstrate that you can carry out a safe isolation procedure in the correct sequence to ensure the safety of not only yourself but everyone else on site. You’ll also undertake and document an assessment of any risks to safety that may be present.

You will be allowed a minimum of 10 minutes to read this section and prepare for assessment.

To demonstrate your occupational competence, you’ll carry out the correct sequence for safe isolation of a distribution board to allow you to safely complete an installation.

SAFE ISOLATION PROCEDURE

1. Identify your point of isolation
2. Inform the customer that you will be isolating the supply.
3. Operate the isolator and lock off and fit warning notice
4. Select approved test equipment and prove that it is working.

Test on the outgoing side of isolator all combinations:

  • L1 and L2
  • L1 and L3
  • L1 and Neutral
  • L1 and Earth
  • L2 and L3
  • L2 and Neutral
  • L2 and Earth
  • L3 and Neutral
  • L3 and Earth
  • Neutral and Earth

6. Re-prove your test equipment is working.

RISK ASSESSMENT

The aim is to make sure that no one becomes ill or gets hurt at the facility. There are three steps to achieve this:

1. Identify the Hazards

Look at what may cause harm to candidates, centre staff, or other people, because of a work activity.

2. Decide Who Might be Harmed and How

Look at who may be affected by the work activity, how they may be affected; this may include other candidates and centre staff.

3. Evaluate the Risks and Decide on Precautions

If you find a hazard, there may be a risk to other people; you need to decide what steps must be taken to eliminate or reduce those risks as far as is reasonably practical. Bear in mind:

  • What needs to be done depends on whether the hazard is low risk or high risk
  • You can determine this by looking at what type of injury may occur and how often it may happen
  • It may be possible to remove the hazard altogether or to take steps to reduce this risk to an acceptable level
  • If there is no risk present, then you do not need to take any action
  • Record ‘No action required’ on the Risk Assessment document.

You also need to carry out a review of safe working practices and undertake a risk assessment in accordance with organisational requirements and procedures prior to commencing the Composite Installation. Record your findings on the relevant documentation.
