MECT06009 2016 Electromechanical Technology

Work safely in an electrical workshop setting.

Identify and specify cables and cable systems for ELV and LV systems.

Identify, specify and install functional and protection devices for ELV and LV systems.

Terminate solid and stranded cables for ELV and LV systems.

Read, and create layout diagrams, wiring diagrams and schematic diagrams for ELV and LV control and power circuits.

Construct, test and troubleshoot ELV and LV lighting, power and motor control circuits

This module will be taught in the electrical workshop using a blend of instruction, demonstration, and application (practical).

The students will be taught small chunks of theoretical material which will include extensive demonstration using the varied resources available in the workshop after which they will complete a related practical project which will then be tested. They will get immediate feedback, supplementary theoretical instruction and then re-do or improve the project until it reaches the standard required. This may require several attempts and will provide many opportunities for the student to learn trouble shooting skills and to improve their general electrical installation skills.

The student will complete several of these projects.

The student will be assessed on a combination of events

1. Final exam

2. Report writing

3. Workshop projects.

Because of the nature of the subject the student has to pass the practical (Workshop) element of the module. If this part is not passed the student must repeat attend.

Workshop Practice:

Tool choice and safety. Workshop organization and safety. Working with electricity and safety. Cutting steel and plastic conduit and trunking with a hacksaw.Threading Steel conduit. Drilling steel and PVC conduit. Erecting conduit and trunking systems.

Cabling:
