This unit covers the preparation and/or checking of activities required to place the high voltage (HV) distribution and sub-transmission network in a state in which work can safely be performed whilst minimising customer outages. The format is typically a written sequence of switching items in a pre-defined format.

It includes planning outages and taking into account loading of network components. It also includes planning the management of multiple outages on the HV distribution and sub-transmission network and the calculation of network loading conditions to ensure the network is operating within designed parameters.

The application of the skills and knowledge described in this unit may require a licence/registration to practice in the workplace subject to regulations for undertaking of electrical work.

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