Elements and Performance Criteria

The Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available.

What does extra low voltage (ELV) wiring refer to?
This refers to 36 volts or less and applies to wiring used in milking equipment systems such as pulsation systems, in irrigation systems between controllers and system components such as solenoid valves, and in domestic garden lighting systems.

What OHS policies and procedures may be relevant to this standard?
OHS policies and procedures may include systems for the prevention of electrical injury, hazard identification and risk control measures, the safe operation and maintenance of machinery and equipment, and the selection, use and maintenance of relevant personal protective clothing and equipment.

What equipment might need to be available for installation work?
Equipment may include a range of power and hand tools, mechanics tool kit and first aid kit.

What do systems consist of?
Systems include wiring, switching mechanisms, circuit protection devices and electronic pulsators, wiring looms, conduits and cabling covers.

What evidence is required to demonstrate competence for this standard as a whole?
Competence in installing and terminating extra low voltage wiring systems requires evidence that a person can plan, design and carry out installation of wiring enclosures, cable support systems, cables and accessories in electrical systems of 36 volts or less and undertake checks that the system conforms to requirements and operates effectively.
The skills and knowledge required to install and terminate extra low voltage wiring systems must be transferable to a different work environment. For example, extra low voltage wiring may be installed in a range of agricultural and horticultural situations.
What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts, and to deal with unplanned events. The knowledge requirements for this competency standard are listed below:

basic electricity and electrical principles relating to extra low voltage wiring
milking equipment, garden lighting and/or irrigation system wiring materials and techniques
isolation and tagging procedures
computerised controller systems
enterprise policies and procedures
testing equipment and procedures
OHS guidelines for installing extra low voltage wiring.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, appropriate literacy and numeracy levels as well as some complementary skills are required. These include the ability to:

read labels and signage to differentiate between extra low voltage and other electrical systems
read and follow enterprise procedures for irrigation system wiring
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.

Are there other competency standards that could be assessed with this one?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.
