This unit involves the skills and knowledge required to select, arrange and terminate circuits, control and protection devices and systems for electrical installations operating at low voltage (LV).
It includes protection of persons and property, correct functioning, ensuring compatibility with the supply, arranging installation into circuits, selecting and arranging switchgear/control gear and protective devices to meet compliance requirements, and documenting arrangement decisions.
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 volt (V) alternating current (a.c.) or 120 V direct current (d.c.).
Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, a relevant contract of training, such as an Australian Apprenticeship, may be required.


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, including 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:
*determining the extent and nature of the installation from job specifications
*arranging the control and protection for electrical installations with and without safety services
*arranging, testing and terminating a multiple earthed neutral (MEN) earthing system
*applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures and practices
*applying safety principles for electrical systems in buildings and premises
*applying sustainable energy principles and practices
*calculating prospective fault current in accordance with minimum fault levels specified by local supply authority
*calculating earth fault-loop impedance
*dealing with unplanned events/situations in accordance with workplace procedures in a manner that minimises risk to personnel and equipment
*determining requirements for discrimination and back-up protection for coordination of protection devices
*determining individual load requirements
*arranging and terminating circuits, control and protective devices to comply with requirements
*selecting circuit protective devices and residual current devices (RCDs) that comply with all requirements
*selecting minimum size-earthing conductors in accordance with relevant industry standards
*selecting circuit breakers to operate when installation is in island mode
*selecting RCDs/residual-current circuit breaker with overcurrent protection (RCBO) to operate when installation is in island mode
*drawing arrangements of 2-pole RCDs, 4-pole RCDs and combination RCDs
*obtaining evidence of compliance for the equipment selected
*dividing installation into circuits
*selecting equipment for damp situations
*coordination of protection devices and circuit wiring
*selecting overcurrent protection devices, circuit breakers and RCDs/RCBOs selecting fuses, emergency controls, isolation devices, functional controls and shutdown devices
*selecting a device for fault current limiting protection
*documenting installation arrangement, specification for items selected and reasons for the selections made.

Required reading
