Scope and fundamental principles, nominal voltages, conductor identification, isolation and switching, special locations, and applying the Wiring Rules to installation design and compliance

Current-carrying capacity, reference temperatures, grouping and thermal derating factors, the mV/A.m voltage-drop method, and the order of cable-selection checks

Applying diversity and Appendix C/Table C1 demand factors to size consumer mains, the main switch and the supply for domestic and commercial installations

Overload and short-circuit protection, the Ib <= In <= Iz coordination rule, RCD types and 30 mA additional protection, discrimination, and the division-of-circuits principle

The Multiple Earthed Neutral system, the MEN link at the main switchboard, main earthing conductor sizing (Table 5.1), equipotential bonding, earth electrodes and the adiabatic equation

Prospective fault current and breaking capacity, earth fault loop impedance (Zs = Ze + R1 + R2), and the 0.4 s and 5 s maximum disconnection times

Point of supply, consumer-mains and submains definitions, sizing mains to the maximum demand, keeping neutral and earth separated downstream, and associated earthing

The Electrical Safety Act 2002 (Qld), the Electrical Safety Office, licensing duties, safe isolation, construction-site requirements (AS/NZS 3012), and the correct testing-and-compliance documentation

The AS/NZS 3000 Section 8 test sequence, earth continuity, insulation resistance (1 MOhm at 500 V DC), polarity, RCD testing and loop-impedance verification
