Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

UEENEEG002B Solve problems in single and three phase low voltage circuits

Course Description

This unit covers selection of equipment for electrical installations operating at voltages up to 1,000V a.c. or 1,500 V d.c. to meet performance standards. This encompass schemes for protection of persons and property, correct function, compatibility with the supply, arrangement of circuits and selection of switchgear, controlgear, protection devices and wiring based on calculated and deemed-to-comply solutions.
