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 5 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.
Unit 399 – Electrotechnical Occupational Competence
The AM2 Practical Assessment (Unit 399) is designed to enable candidates to demonstrate ‘Electrotechnical occupational competence’ in accordance with approved industry practices and the current statutory and non-statutory regulations:
- The Electricity at Work Regulations (1989)
- The current edition of BS7671 Wiring Regulations
- Health & Safety Act (1974)
- Building Regulations (2000)
- Management of Health & Safety at Work Regulations
- Reporting of Injuries, Diseases & Dangerous Occurrences Regulations
- Provision & Use of Work Equipment Regulations
- Manual Handling Operations Regulations
- Personal Protective Equipment at Work Regulations
- Work at Height Regulations
- Control of Substances Hazardous to Health Regulations
- Control of Asbestos at Work Regulations
The outcomes and the assessment criteria of this unit underpin the electrotechnical industry’s competence requirements for qualified operatives in an installation or maintenance role.
There are eight learning outcomes in this unit. The learner will be able to:
- Interpret specifications, drawings, and diagrams
- Undertake risk assessments
- Carry out the safe isolation of electrical circuits and complete electrical installations
- Plan and prepare to install, terminate and connect wiring systems
- Complete the installation, termination, and connection of wiring systems in accordance with industry requirements
- Complete the visual inspection, initial verification, and certification of an electrical installation
- Complete the testing and certification of an electrical installation in accordance with industry requirements
- Diagnose, and recommend how to rectify, electrical faults in an electrical installation in accordance with industry requirements.
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
- A central heating/sustainable energy system
- A safety services circuit and device
- A data-cabling system
The assessment is in four sections:
- Section A and A1 – Risk Assessment and Safe Isolation; Composite Installation
- Section B – Inspection and Testing of the completed composite installation
- Section C – Safe Isolation (C1) and Fault Diagnosis and Correction (C2)
- Section D – Assessment of Applied Knowledge
Section A1: Risk Assessment and Safe Isolation (1 Hour)
Section A: Composite Installation (8.5 Hours)
This section has areas where candidates will need to demonstrate occupational competence in accordance with statutory and non-statutory regulations and approved industry working practices.
The areas are:
- Risk assessment and safe-isolation.
- Interpretation of specifications and technical data.
- Selection of protective devices.
- Install Protective Equipotential Bonding.
- Installing and terminating pvc singles cable.
- Installing and terminating pvc/pvc multi-core & cpc cable.
- Installing and terminating SY multi-flex cable.
- Installing and terminating heat-resistant flex.
- Installing and terminating XLPE SWA.
- Installing and terminating data-cable.
- Installing and terminating FP200 type cable.
Section B: Inspection and Testing (3.5 hours)
To demonstrate occupational competence candidates will be expected to:
- Undertake an assessment of risk and work according to best practise as required by Health and Safety legislation.
- Ensure the installation is correctly isolated before commencing the inspection and test activity.
- Carry out a visual inspection of the installation in accordance with BS 7671 and IEE Guidance Note 3.
- Complete the following tests on the installation in accordance with BS 7671 and IEE Guidance Note 3:
- Continuity of protective conductors
- Continuity of ring final circuit conductors
- Insulation resistance
- Earth fault-loop impedance (EFLI)
- Prospective fault current (PFC)
- Functional testing
Candidates will be required to verify that the test results obtained conform to the values required by BS 7671 and IEE Guidance Note 3.
Complete an electrical installation certificate, schedule of inspections and schedule of test results using the model forms as illustrated in Appendix 6 of BS 7671.
Section C: Safe Isolation and Fault Diagnosis (2.5 hours)
Section C1 Safe Isolation: 30 minutes
Section C2 fault diagnosis: 2 hours
To demonstrate occupational competence candidates will be expected to:.
- Undertake an assessment of risk.
- Correctly identify and use tools, equipment and test instruments that are fit for purpose.
- Carry out checks and preparations that must be completed prior to undertaking fault diagnosis.
Carry out safe isolation in the correct sequence for
i) a designated single phase circuit
ii) a designated three phase circuit
iii) the complete installation
Identify faults from ’fault symptom’ information.
- State and record how the identified faults can be rectified.
- Candidates will be expected to follow practices and procedures that take into account voltage sensitive equipment.
Section D: Assessment of Applied Knowledge (1 hour)
Candidates will be assessed on their application of knowledge associated with the work undertaken within the Assessment of Occupational Competence.
The Section D assessment will last for one hour and be in the form of a computerised multiple choice test.
Candidates will be expected to answer 30 questions and achieve a pass mark of 70%, thus requiring candidates to achieve 21 correct answers.
