QLD Electrical Licence study guide
QLD Electrical Licence · Work through your exam, one topic at a time.
The Queensland electrical licensing examination is the assessment step that sits between a candidate's trade training and the electrical work licence issued in Queensland. It is aimed at people who have completed (or are close to completing) an electrical apprenticeship or equivalent qualification and who now need to demonstrate, under exam conditions, that they can apply their knowledge to real installation decisions rather than simply recall it. The QLD Electrical Licence study guide has 5 sections and about 2,255 words.
01Electrical theory and fundamentals
Ohm's law (V = IR), the power relationships (P = VI = I²R = V²/R) and the impedance triangle (Z = √(R² + X²)) underpin almost every calculation question. For AC, inductive reactance X L = 2πfL, capacitive reactance X C = 1/(2πfC), and current is V/Z.

AS/NZS 3000 is not optional in Queensland: it is called up by the electrical safety legislation, so its requirements are legal duties. Know the companion standards it depends on - AS/NZS 3008 for cable selection, AS/NZS 3017 for verification, AS/NZS 3012 for construction sites, AS/NZS 3760 for in-service testing and AS/NZS 4836 for safe working.

Electrical work in Queensland is governed by the Electrical Safety Act 2002 (Qld), supported by the Electrical Safety Regulation and codes of practice. The Act's object is to eliminate or minimise electrical risk to people and property.

Sound installation practice starts with the load: calculate maximum demand, then select a cable whose current-carrying capacity, after every applicable derating factor, is at least the rating of the protective device. AS/NZS 3008 gives ratings for each installation method (clipped direct, enclosed in a wall, in conduit, buried) plus correction factors for ambient temperature (C a), grouping (C g), thermal insulation (C i) and soil conditions.

Work through the hierarchy of control rather than reaching for PPE first. The best control for electrical risk is elimination: de-energise, isolate, lock and tag, then prove dead.
