NSW Electrical Licence study plan

NSW Electrical Licence · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Electrical principles and theory

  • Solve 40 Ohm's law and series/parallel resistance problems without reference notes, targeting 90% accuracy

  • Explain the relationship between voltage, current, resistance and power in single-phase and three-phase circuits in your own written words

  • Calculate power factor, apparent power and reactive power for three mixed inductive/resistive loads

  • Derive and apply the star and delta transformation formulas to two worked circuit examples

Your checkpoint

A one-page formula sheet plus a 40-question self-test scored and annotated with every error explained

Week 2

Electrical principles and theory & Wiring systems and installation practices

  • Compute voltage drop for five cable runs and select compliant conductor sizes from current-carrying capacity tables

  • Identify the correct cable type and installation method for six described environments including underground, ceiling space and wet areas

  • Sketch a single-line diagram for a small domestic installation showing subcircuits, protective devices and main switch

  • Interpret a set of manufacturer cable derating factors and apply them to bundled and thermally insulated runs

Your checkpoint

A worked installation design pack: load schedule, cable selection table and single-line diagram for a three-bedroom dwelling

Week 3

Wiring systems and installation practices

  • List the wiring system requirements for at least eight specific locations such as bathrooms, kitchens, workshops and outbuildings

  • Describe correct termination, support and protection practices for fixed wiring and flexible cords in three installation scenarios

  • Explain the rules governing separation of electrical and communications cabling and apply them to a described wall cavity

  • Produce an inspection checklist covering mechanical protection, access, identification and segregation of circuits

Your checkpoint

A completed inspection checklist applied to a described installation with at least ten non-compliances identified and corrected

Week 4

Electrical protection and earthing

  • Explain the operation of circuit breakers, residual current devices and fuses and match each to the fault type it protects against

  • Determine the required protective device rating and disconnection time for a given circuit using earth fault loop impedance values

  • Describe earthing system arrangements for a MEN installation and explain why each bonding connection exists

  • Calculate prospective earth fault current from loop impedance and verify it exceeds the device trip threshold

Your checkpoint

A protection coordination worksheet covering five circuits, each with device selection, loop impedance calculation and disconnection time verification

Week 5

Testing, verification and fault finding & Electrical equipment and appliances

  • Sequence the mandatory verification tests for a new installation and state the acceptable outcome for each

  • Interpret insulation resistance, polarity, continuity and loop impedance results and diagnose the fault implied by three abnormal readings

  • Evaluate appliance nameplate data and classify equipment by protection class and ingress rating

  • Describe the safety checks required before returning a faulty appliance to service

Your checkpoint

A mock test report for a described installation with all results recorded, three faults diagnosed and corrective actions stated

Week 6

Testing, verification and fault finding & Work health and safety obligations

  • Trace five described faults to root cause using a structured logical fault-finding method

  • Apply the hierarchy of risk control to three electrical work scenarios and justify your chosen controls

  • State the isolation, tagging and testing steps required before working on de-energised equipment

  • Identify the hazards and required controls for working near live parts and in confined spaces

Your checkpoint

A written safe work method statement for a described task plus a fault-finding log for five scenarios

Week 7

Regulatory framework and licensing requirements & Work health and safety obligations

  • Outline the regulatory chain from legislation through regulation to standards and explain how each level affects daily work

  • Describe the licensing obligations, supervisory requirements and notification duties that apply to electrical work

  • Explain compliance testing and certification responsibilities for new and altered installations

  • Summarise employer and worker duties under work health and safety law in your own words

Your checkpoint

A two-page summary map linking each regulatory instrument to a concrete on-site obligation, cross-checked against your own notes

Week 8

Electrical principles and theory & Wiring systems and installation practices & Electrical protection and earthing & Electrical equipment and appliances & Testing, verification and fault finding & Work health and safety obligations & Regulatory framework and licensing requirements

  • Complete two full-length timed practice exams under exam conditions and score each by domain

  • Re-teach your three weakest domain areas from memory without notes

  • Review every missed question and write the correct reasoning for each

  • Consolidate formula sheet, checklists and regulatory map into a single revision pack

Your checkpoint

A scored domain-by-domain performance report with a prioritised list of remaining gaps and a final one-page revision sheet
