Description
This unit covers the process of installing wiring enclosures, cable support systems, cables and accessories in electrical systems of 36 volts or less and defines the standard required to: plan, design and carry out installation of wiring enclosures, cable support systems, cables and accessories in electrical systems of 36 volts or less; undertake checks that the system conforms to requirements and operates effectively; read labels and signage to differentiate between extra low voltage and other electrical systems; size cables and wires to suit calculated load; check and notify completed installation activities; follow enterprise OHS procedures and safely work with extra low voltage systems.
Notes
Elements and Performance Criteria
1. Plan and prepare for installation of extra low voltage wiring
  • 1.1. Installation is planned and prepared to ensure OHS policies and procedures are followed, and the work is appropriately sequenced according to requirements.
  • 1.2. Appropriate personnel are consulted to ensure the work is co-ordinated effectively with others on the work site.
  • 1.3. Cables and wires are sized to suit calculated load.
  • 1.4. Wiring system components are checked against job requirements.
  • 1.5. Accessories are obtained according to established procedures and to comply with organisational and task requirements.
  • 1.6. Location in which specific items of accessories, apparatus and circuits are to be installed is determined from job requirements.
  • 1.7. Materials necessary to complete the work are obtained according to established procedures and checked against the job requirement.
  • 1.8. Tools, equipment and testing devices needed to carry out the installation work are obtained, following established procedures they are checked for correct operation and safety.
  • 1.9. Preparatory work is checked to ensure that it complies with requirements and no unnecessary damage has occurred.
2. Install wiring systems
  • 2.1. Occupational Health and Safety (OHS) policies and procedures for installing electrical wiring systems are followed.
  • 2.2. Wiring systems are installed to meet requirements, without damage or distortion to the surrounding environment or services.
  • 2.3. Accessories are terminated and wires are connected as required to solenoids and controllers, according to manufacturer and enterprise requirements.
  • 2.4. Unplanned events or conditions are responded to using established procedures.
  • 2.5. Approval is obtained from appropriate personnel according to established procedures before any contingencies are implemented.
  • 2.6. On-going checks of the quality of the work are undertaken according to established procedures.
3. Check and notify completion of work
  • 3.1. Final checks are undertaken to ensure the installed wiring systems conforms to requirements.
  • 3.2. System is tested to ensure that it works.
  • 3.3. Work completion is notified according to established procedures.

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:
plan, design and carry out installation of wiring enclosures, cable support systems, cables and accessories in electrical systems of 36 volts or less
undertake checks that the system conforms to requirements and operates effectively
read labels and signage to differentiate between extra low voltage and other electrical systems
size cables and wires to suit calculated load
check and notify completed installation activities
follow enterprise OHS procedures and safely work with extra low voltage systems.
Context of and specific resources for assessment
Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.
