Outcome 3 - Be able to correct faults on electrical systems and equipment

The assessment criteria is that the learner can:
1. Confirm appropriate repairs, removals and replacements and their implications with relevant people including:
* Other workers / colleagues
* Customers / clients
* Representatives of other services
2. Perform fault correction procedures correctly and safely using appropriate tools, equipment and material
3. Perform the removal and replacement of components and associated equipment from electrotechnical systems to ensure:
* Ease of access to enable future maintenance
* Accordance with:
– relevant regulations
– manufacturer’s instructions
– organisational procedures
4. Apply appropriate procedures to ensure electrotechnical systems, equipment and components are left safe, in accordance with industry regulations, if the fault cannot be corrected immediately
5. Perform appropriate inspection and testing procedures to confirm that systems, equipment, and components are functioning correctly after completion of fault correction work
6. Record test results and other appropriate information regarding the fault correction work clearly and accurately and report to relevant people, such as:
* Other workers / colleagues
* Customers / clients
* Representatives of other services.

Unit 399 – Electrotechnical Occupational Competence (AM2)

This unit is designed to enable learners 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.

 

To undertake this unit, learners must provide auditable formal evidence that they have the relevant electrotechnical knowledge, understanding, experience and skills at the appropriate level that enables them to carry out the assessment activities effectively and safely as prescribed for each learning outcome.

This unit must only be assessed in a National Electrotechnical Training (NET) approved centre. All criteria set by NET must be met full and continuously for each assessment. NET, rather than City & Guilds, should be contacted regarding any queries regarding the delivery and/or assessment for this unit.

As with all assessments, the candidates result for this unit must be submitted to City & Guilds on the Walled Garden to allow for certification.

This unit will be assessed by:

  • A knowledge assessment at a NET approved AM2 centre
  • A simulated practical exercise at a NET approved AM2 centre.
