Description
This unit of competency has been developed for Engineering Tradesperson - industrial electrician apprenticeship training, and the recognition of trade-level skills in selecting cables for electrical installation work and equipment in areas including consumer mains, submains and final subcircuits for operating voltages up to 1000 V alternating current (AC) or 1500 V direct current (DC).It covers a comprehensive understanding of the cable selection process of AS/NZS 3000:2007 Electrical Installations (known as the Australian/New Zealand Wiring Rules) and cable selection standards in determining maximum demand, voltage drop limitations, current carrying capacity and short circuit capability.This unit covers the skills and knowledge required to meet the Electrical Regulatory Authorities Council (ERAC).Essential Performance Capabilities (EPCs) classified as ‘critical’:EPC 21 - Demonstrate the ability to select cables for mains and submains using AS/NZS 3000 and AS/NZS 3008.1 based on current carrying capacity, short circuit capability, maximum demand and voltage drop, for single phase and three phase installations including multiple installations.EPC 22 - Demonstrate the ability to select cables for final subcircuits using AS/NZS 3000 and AS/NZS 3008.1 based on current carrying capacity, short circuit capability, maximum demand, earth loop impedance and voltage drop.EPC 27 - Demonstrate knowledge of AS/NZS 3000 and local regulatory requirements for the installation of aerial conductors and underground wiring. Including specialist cables.Some jurisdictions require the holder of this unit to be licensed or certified and users should check with the relevant authorities.Band: AUnit Weight: 4
