Description
This unit of competency has been developed for Engineering Tradesperson - industrial electrician apprenticeship training and the recognition of trade-level skills in inspecting, testing and verifying electrical installations in accordance with the AS/NZS 3000:2007, Electrical Installations (known as the Australian/New Zealand Wiring Rules) and regulatory requirements. It covers all aspects inspection and testing, including visual, application of mandatory testing, interpreting test results and recording reporting requirements. This unit covers the skills and knowledge required to meet the Electrical Regulatory Authorities Council (ERAC).Essential Performance Capabilities (EPCs) classified as ‘critical’:EPC 26 - Demonstrate the appropriate methods for the installation, modification and testing of electrical installations and equipment for construction and demolition sites, complying with AS/NZS 3012 and applicable workplace safety legislation. Need for calibration of instruments.EPC 30 - Demonstrate to AS/NZS 3000 and AS 3017 standards the electrical checks and tests required to ensure electrical installations are safe, reporting of test results typically required to satisfy regulatory requirements.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
