This unit involves the skills and knowledge required to select and arrange electrical equipment into distribution circuits for installations associated with construction and demolition sites, transportable structures and vehicles, including their site supplies, marinas, electromedical treatment areas (patient areas), and shows and carnivals operating up to 1,000 volt (V) alternating current (a.c.) or 1,500 V direct current (d.c.).

It includes arranging the installation for correct functioning and safe connection to supply by the selection of switchgear, control gear, protection devices and wiring based on calculated and deemed-to-comply solutions. It also includes completing electrical installation documentation.

The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 V a.c or 120 V d.c.

Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, a relevant contract of training, such as an Australian Apprenticeship, may be required.

Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in suitable simulated workplace operational situations that replicate workplace conditions.

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.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or other simulations

relevant and appropriate materials, tools, facilities, equipment and personal protective equipment (PPE) currently used in industry
