This unit involves the skills and knowledge required to install high current equipment and switchgear in the electricity supply industry (ESI).

It includes installing direct current (d.c.) switchgear and other equipment, such as rectifier transformers, rectifiers, invertors, isolators and links, harmonic filters, negative reactors and energy dissipation resistors EDR’s to ensure correct installation to workplace procedures and industry standards.

It also includes isolating systems and/or circuits for safe working in accordance with work plans, visual inspections and necessary checks to ensure equipment and components have been correctly installed in accordance with design and are in a safe condition for pre-commissioning tests prior to energisation, as well as updating installation data and relevant quality assurance documentation.

The application of the skills and knowledge described in this unit may require a licence/registration to practice in the workplace.

Other conditions may apply under state and territory legislative and regulatory licensing requirements which must be confirmed prior to commencing this unit.
