Unsupervised apprentice, live socket replacement and missing certification
A licensed electrical contractor sends a first-year apprentice alone to a rental unit to 'swap three GPOs and a light switch' while he attends another job across town. The apprentice has no test equipment, no lock and no written instructions. The switchboard is accessible in the hallway but the tenant is not home, so the apprentice cannot confirm which circuits are which and decides to work with the power on because the property manager wants the unit ready to re-let that afternoon. The replacement socket outlets are the same type as the originals in a brick wall. The contractor says he will 'sort the paperwork out on Friday'. The apprentice is not sure whether the work is notifiable.
1. Identify what is wrong with this arrangement under Queensland electrical safety law and what the consequences are for the contractor and the apprentice.

Key issues:
- Unlicensed electrical work. Under the Electrical Safety Act 2002 (Qld), electrical work must be performed by a licensed electrical worker. An apprentice is not licensed and may only perform electrical work under supervision of a licensed electrical worker, to the extent the Electrical Safety Regulation 2013 allows. A first-year apprentice sent alone to carry out installation work is outside that allowance.
- Primary duty. The contractor is a person conducting a business or undertaking and must ensure the way electrical work is carried out is electrically safe, and that the installation is safe. Providing no supervision, no test equipment and no procedure is a failure of that duty.
- Live work. Replacing socket outlets is readily done de-energised. Working live because a tenant is absent and a manager is impatient is not a justification.
- Consequences: improvement and infringement notices, on-the-spot fines, prosecution with substantial penalties, and referral to the Electrical Licensing Committee with risk to the contractor's licence. The apprentice also faces disciplinary action for performing work outside their competence and supervision. If a tenant is injured, the exposure escalates sharply.
Check the current Regulation and ESO guidance for the exact supervision and penalty provisions before relying on them.
2. What supervision and competence requirements should have been in place, and what should the apprentice have done on arrival?
Read the worked answer
Supervision: the level of supervision must match the apprentice's stage and demonstrated competence. For a first-year apprentice that means direct, on-site supervision by a licensed electrical mechanic - not a phone call. The supervisor must be contactable, able to attend, and must not give work beyond the apprentice's competence.
Resources the apprentice needed: test equipment (insulation resistance, continuity, loop impedance, RCD tester), locking-off devices and tags, a circuit schedule or means of identifying circuits, and written instructions.
On arrival the apprentice should have:
- Refused to proceed unsupervised - asking for the supervisor to attend.
- Not commenced live work.
- If isolation were possible: identified the correct circuit, isolated at the switchboard, locked and tagged, proved dead at the point of work, and confirmed with a tester proven on a known live source before and after.
- Notified the contractor and the property manager that the job would be rescheduled if supervision could not be provided.
Working live to meet a re-letting deadline is exactly the pressure the hierarchy of control exists to resist.
3. What testing and certification must accompany this work, and who can sign it?
Read the worked answer
Testing before energising and before handover:
- Visual inspection of connections, conductor identification, cable damage and enclosure integrity.
- Continuity of the protective earthing conductor to each replaced accessory and to the earthing system.
- Insulation resistance at 500 V DC with loads removed (minimum 1 MΩ).
- Polarity at each accessory and correct active/neutral/earth connection.
- Earth-fault loop impedance at each outlet against the protective device's maximum Zs.
- RCD operation (no trip at 50%, trip 15–30 mA within 300 ms, plus test button), where the circuit is RCD protected.
Certification: the work is notifiable. The contractor must lodge the Electrical Work Request with the Electrical Safety Office and issue the customer a Certificate of Test and Compliance, and the results must be recorded on it. Only the licensed contractor can certify the work - the apprentice cannot sign off their own unsupervised work, and signing a certificate for work the contractor neither supervised nor tested would compound the breach. Confirm current QLD notification timeframes and forms with the ESO before submitting.
