Licensing and Standards (AS/NZS 3000 and Related)
Licensing questions test the boundary between what a licensed electrician may do, what a supervisor must oversee, and what requires notification or certification. In most jurisdictions, prescribed electrical work must be done by or under the supervision of a licensed person, and safety-critical work (consumer mains, mains connection, certain repairs) demands direct supervision rather than remote oversight. Certificates of electrical safety or compliance are legal instruments: signing one you did not personally verify is misconduct.
The standards family matters too. AS/NZS 3000 is the core, but candidates must recognise AS/NZS 3008 (cable selection), AS/NZS 3017 (verification guidelines), AS/NZS 4836 (safe work on low-voltage installations), AS/NZS 61439 (assemblies), AS/NZS 3003 (patient areas), AS/NZS 60079 series (hazardous areas) and AS/NZS 3012 (construction sites).
Traps: assuming a licence from one state transfers automatically (mutual recognition exists but conditions differ); believing a contractor licence alone authorises technical work; confusing a Certificate of Compliance with an Electrical Safety Certificate or with the distributor's connection approval; and overlooking that supervisory duties include verifying competence, not just presence.
Worked example: A contractor wants an apprentice to connect consumer mains unsupervised. The correct answer: this is prescribed work requiring direct supervision by a licensed supervisor, and the certificate must be signed by the licensed person who verified the work - the apprentice cannot certify it regardless of experience.
