Description
This unit involves the skills and knowledge required to plan electrical installation with a low voltage (LV) demand up to 400 ampere (A) per phase.It includes planning, arranging and identifying resources for an electrical installation. It also includes arrangement of circuits; metering and control; cable route planning; specifying type and rating of switchgear, control gear, protection devices and wiring based on calculated and deemed-to-comply solutions and planning documentation.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Plan electrical installation
- 1.1 Work health and safety (WHS)/occupational health and safety (OHS) risk control measures and workplace procedures for carrying out work are followed
- 1.2 Nature of the electrical installation is determined from job specifications
- 1.3 Safety and regulatory requirements for electrical installation are identified, obtained and applied in accordance with relevant industry standards and safe work practices
- 1.4 Electricity tariffs required are discussed with appropriate person/s to determine control and metering needs of the installation
2 Arrange installation circuits, control and metering
- 2.1 Circuits are arranged to ensure safe and functional operation of the installation in accordance with relevant industry standards
- 2.2 Circuits are arranged in accordance with relevant industry standards and job specifications
- 2.3 Control and metering of the installation are arranged in accordance with relevant industry standards and job specifications
- 2.4 Earthing is arranged in accordance with relevant industry standards and energy supplier requirements
3 Identify cables protection and switchgear
- 3.1 Fault levels at relevant point/s of the installation are determined from calculations and/or information from the energy supplier
- 3.2 Wiring systems selected are confirmed as meeting sustainable energy practices and job specifications
- 3.3 Cable conductor sizes are confirmed to meet current-carrying capacity requirements and voltage-drop and fault-loop impedance limitations and short circuit performance
- 3.4 Protection methods and devices are identified to meet coordination requirements for overload and short circuit protection
- 3.5 Switchgear and control gear are identified to meet fault levels, current voltage and ingress protection (IP) ratings and functional requirements
- 3.6 Earthing system components are identified to meet requirements of the earthing system used
- 3.7 Evidence is obtained that electrical equipment selected is in accordance with WHS/OHS and safe work practices
4 Document electrical installation plan
- 4.1 Equipment identified for the installation is documented with supporting calculations in accordance with workplace procedures
- 4.2 Electrical installation is documented in accordance with workplace procedures and forwarded to relevant person/s
