(Corequisite units must be studied concurrently with this unit)
Overview
This unit involves the skills and knowledge required to terminate cables, cords and their conductors at accessories and current-using devices, designed to operate at voltages up to 1,000 volts (V) alternating current (a.c.) or 1,500 V direct current (d.c.).
It includes working safely to industry standards, wiring systems, cable types and applications; selecting appropriate termination accessories; preparing and terminating cables and cords; terminating cables/cord conductors; and ensuring completed termination complies with industry standard requirements.
The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 V a.c. or 120 V d.c.
Assessment
For Melbourne campuses
Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, incl the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:

*applying sustainable energy principles and practices
*confirming relevant circuits are isolated dealing with unplanned events in accordance with workplace procedures in a manner that minimises risk to personnel and equipment
*terminating wiring and accessories for low voltage circuits, including:
*cutting cable ends and stripping sheath/insulation to a sufficient length
*fitting and securing cable glands/retaining devices correctly
*preparing and terminating conductors to suit the type of terminal at which they are to be connected
*selecting appropriate cable/cord and conductor devices
*testing completed cables to ensure compliant continuity and insulation resistance
*inspecting junction box/terminal enclosures and determining the type and size of required cable and conductor termination devices
