• Engineering Software: Introduction to using digital tools for documentation and basic circuit simulation.

Electrical work is as much a mechanical trade as it is a theoretical science. This subject focuses on the physical installation of equipment, teaching you how to select the right fixings for different building materials and how to manipulate conduits and cables to create professional, compliant installations.

Topics include:

• Tool Mastery: Safe and effective use of hand and power tools specific to the electrical trade.
  
  
• Fabrication Techniques: Cutting, bending, and joining PVC and metallic conduits and trunking.
  
  
• Fixing & Securing: Selecting masonry anchors, cavity fixings, and chemical anchors based on weight and substrate.
  
  
• Termination Excellence: Mastering the techniques for stripping and terminating power cables and flexible cords.
  
  
• Soldering: Applying soft soldering techniques for permanent electrical connections.

Most modern electrical infrastructure operates on Alternating Current. This subject transitions you from DC to AC, exploring the complex world of magnetism, induction, and phase relationships. You will learn to solve circuit problems where resistance is joined by reactance and impedance.

Topics include:

• Electromagnetism: Understanding flux density, reluctance, and the operation of solenoids and relays.
  
  
• AC Fundamentals: Analyzing sine waves, frequency, RMS values, and phase angles.
  
  
• Reactance & Impedance: Calculating the effects of capacitors and inductors in AC circuits.
  
  
• Power Factor: Understanding the “efficiency” of an AC circuit and the methods for power factor correction.
  
  
• Phasor Diagrams: Using vector diagrams to represent and solve complex AC circuit values.

This subject brings electrical theory into motion. By studying machines and transformers, you will understand how electricity is converted into mechanical force and how voltage levels are stepped up or down for distribution. You will learn the practicalities of connecting and testing these critical components.

Topics include:

• Transformer Principles: Calculating turns ratios, voltage regulation, and efficiency in single and three-phase transformers.
  
  
• DC Machine Dynamics: Exploring the construction and operation of series, shunt, and compound DC motors.
  
  
• AC Rotating Machines: Mastering three-phase induction motors, including Star and Delta connection methods.
  
  
• Motor Control: Understanding and wiring basic motor starters, including Direct-on-Line (DOL) and Forward/Reverse.
  
  
• Testing Procedures: Performing insulation resistance and continuity tests on windings.

At the heart of an electrician’s license is the ability to design and install wiring systems that are safe and efficient. This subject focuses heavily on the “Bible” of the trade—the AS/NZS 3000 Wiring Rules—ensuring you can select the correct cable size and protective device for any given load.

Topics include:

• Maximum Demand: Calculating the total load of an installation using the “General Method” and “Individual Assessment.”
  
  
• Cable Selection: Using AS/NZS 3008 to select cables based on current-carrying capacity and environmental factors.
  
  
• Voltage Drop Compliance: Ensuring circuits maintain sufficient voltage for appliance functionality over long distances.
  
  
• Wiring Systems: Selecting and installing enclosures, including underground conduits and aerial supports.
  
  
• Final Sub-Circuits: Designing the layout and protection (RCDs/MCBs) for lighting, power, and appliance circuits.

As industry moves toward “Industry 4.0,” the ability to program control systems is essential. This subject introduces you to the brain of modern industrial machinery: the Programmable Logic Controller. You will learn to replace traditional hard-wired logic with flexible, software-based control.

Topics include:

• PLC Architecture: Understanding CPU, I/O modules, and the interface between hardware and software.
  
  
• Ladder Logic (Discrete): Programming basic start/stop, interlocking, and timer/counter functions.
  
  
• Analogue Control: Handling variables like temperature and pressure through analogue input and output signals.
  
  
• Control Circuit Components: Integrating sensors, limit switches, and contactors into automated systems.
  
  
• Program Verification: Testing and debugging programs to ensure safe machine operation.

A high-level electrician is a professional detective. This subject teaches you how to systematically diagnose problems in existing installations. You will learn how to verify that appliances and circuits are performing to specification and how to safely find the “needle in the haystack” when a circuit fails.

Topics include:

• Diagnostic Methodology: Applying the “Half-Step” and “Input-Output” methods to locate electrical faults.
  
  
• Heating Equipment: Evaluating the performance and controls of water heaters and space heating.
  
  
• Lighting Evaluation: Assessing lighting levels and troubleshooting dimming and control systems (e.g., DALI).
  
  
• Socket Outlet Verification: Testing for correct polarity and earth loop impedance.
  
  
• Safe Isolation: Mastering the “Test-Before-You-Touch” procedure during troubleshooting.

The final subject is where everything comes together for commissioning. You will learn the legal requirements for “signing off” on a job, ensuring the installation is safe for the consumer. This includes specialized knowledge in alternate energy sources and the final verification of the M.E.N. (Multiple Earthed Neutral) system.

Topics include:

• Mandatory Testing: Executing the six mandatory tests required by AS/NZS 3000 before energizing an installation.
  
  
• Visual Inspection: Developing a keen eye for compliance issues in switchboards and wiring.
