F  Ensuring co-ordination between circuit protective device and conductor current-carrying capacity.
G  Selecting compliant earthing system components
H  Documenting wiring systems and cables to be used, specification for items selected and reasons for the selections made.
I  Dealing with unplanned events


Practical activities to develop skill in selection of electrical wiring systems, protective devices, various cables, switchboard, control panels and lightings.

Work simulation assignments on calculations relating to the general installation maximum demand calculations, volt drop considerations and fault conditions. Specifications will be provided with work simulation (team or individual basis) or may be negotiated to suit a workplace based application.

Project: Students are required to spend approximately 20 nominal hours for independent study on technical standards, regulations and codes for general electrical installations. The project within the unit is designed to give learners an introduction to the electrical design process. The method of rating various types of electrical equipment is detailed as is the design of electrical supply, installation and lighting.
