UEENEEG107A - Select wiring systems and cables for low voltage general electrical installations
Overview
This unit covers selecting wiring systems and cables for electrical installations operating at voltages up to 1,000V a.c. or 1,500 V d.c. It encompass knowledge and application of wiring systems and cable types, selecting wiring system compatible with the installation conditions, selecting cables that comply with required current-carrying capacity and voltage drop and earth fault-loop impedance limitations, coordination between protective devices and conductors and documenting selection decisions
Assessment
For Melbourne campuses
Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and 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 and knowledge:
- performance requirements - design and safety;
- final subcircuit arrangements;
- factors affecting the suitability of wiring systems;
- maximum demand on consumer’s mains/submains;
- cable selection based on current carrying capacity requirements;
- cable selection based on voltage drop requirements;
- cable selection based on fault loop impedance requirements;
- selecting protection devices;
- selecting devices for isolation and switching, and;
- switchboards.
Required reading
The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
