This unit covers the isolation, inspection, testing, adjustment, repair, refurbishment and/or overhaul and functional checks of discrete protection and control devices. It includes the requirements to prove the functionality of discrete devices, such as direct current (d.c.) supplies, overcurrent, overload, earth fault, transformer temperature controls, alarms and indication circuits.

The application of the skills and knowledge described in this unit requires 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.
