Description
Employability Skills
Learning Outcomes and Application This unit of competency has been developed for Engineering Tradesperson – industrial electrician apprenticeship training and the recognition of trade-level skills in designing and connecting control switching of circuits.It covers basic switching and control arrangements and hazards and safety requirements associated with static electricity discharge from components.This unit covers the skills and knowledge required to meet the Electrical Regulatory Authorities Council (ERAC).Essential Performance Capabilities (EPCs):EPC 41 – Demonstrate the knowledge and skills to design and connect switching circuits, as per AS/NZS 3000.EPC 51 – Describe the functioning of basic electronic circuits used in common electrical power circuit applications including electronic logic controls, related hazards and safety 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
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must:

have vocational competency in designing and connecting control switching of circuits for building services and industrial equipment at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 and comply with the National Vocational Education and Training Regulator Act 2011 or equivalent legislation covering VET regulation in a non-referring State as the case requires.

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
