This unit covers the installation and maintenance of de-energised low voltage (LV) underground cables and covers the laying of cables as well as the jointing, terminating, repair and replacement of cables. It also includes direct laying of cables in trenches, on racks, in troughs and/or in conduit or ducts; and the isolation of systems and circuits, the procedure of issuing/accepting electrical access permits, the undertaking of pre-commissioning and/or recommissioning tests and the updating of system data/maintenance records.

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.
