Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

LV electrical test equipment must include:

test lights and probes

circuit continuity testers

digital multimeters.

Safety requirements must include:

work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for:

selecting and using personal protective equipment (PPE)

identifying hazards and controlling risks associated with wearing jewellery while working around high current wiring systems.


Performance Evidence

Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in the unit’s elements, performance criteria, range of conditions and foundation skills:
