Describe the purpose of main protective bonding, supplementary bonding and automatic disconnection of supply in a domestic installation.

Verify that residual current devices, miniature circuit breakers and fuses protect against the specific fault types each is designed for.

Select cable type (PVC singles, twin-and-earth, armoured, flexible cord) for five stated installation conditions and justify each choice.

Size conduit and trunking from cable count using the space-factor rule, and lay out a run that respects bend radius limits.

Produce correct terminations for stranded and solid conductors, and state the torque and inspection checks that follow tightening.

Identify the tools needed for a given task and describe the safe-use and inspection routine for each.

Explain the fire-stopping, segregation and support-spacing requirements for a cable passing through a fire-rated wall.

Solve series, parallel and series-parallel resistor networks for total resistance, branch current and voltage drop.

Apply Ohm's law, power equations and the three-phase relationships to ten mixed calculation problems without reference notes.

Convert between single-line, schematic and wiring diagrams for a lighting and socket circuit.

Estimate material quantities and labour hours for one final circuit from a simple layout drawing.

Demonstrate lockout/tagout, proving dead and safe isolation on a practice board in the correct sequence.

Select and inspect personal protective equipment for five stated tasks, and state the rejection criteria for damaged items.

Describe first-aid and emergency response steps for electric shock and arc-flash burns, including rescue without contact.

Perform a practical task to trade standard under time pressure: install, terminate and test one socket circuit.

Explain the viva answers for isolation procedure, permit-to-work and working-at-height precautions.

Explain the construction and operating principle of a three-phase induction motor, including slip and rotating-field production.

Compare direct-on-line, star-delta, auto-transformer and soft-starter methods for starting current, torque and typical application.

Interpret a motor nameplate and connect a dual-voltage motor for the correct supply.

Draw and explain a direct-on-line starter circuit with contactor, overload relay, start and stop pushbuttons and a holding contact.

Describe the tests and maintenance checks for a transformer and an induction motor before return to service.

Perform insulation resistance, continuity, polarity, earth-fault loop impedance and RCD trip-time tests on a practice installation and record results correctly.

Diagnose five injected faults from symptoms and test results, and state the corrective action for each.

Explain how a diode, transistor and thyristor behave in a circuit, and identify their terminals on a component.

Describe the role of a rectifier, inverter and variable-frequency drive in a modern installation, and state one safety consideration for each.

Read a simple electronic schematic and predict the output of a half-wave rectifier with a smoothing capacitor.

Complete two full practical jobs end to end: plan, install, terminate, test and hand over, within the exam time allowance.

Demonstrate correct bending, cutting and threading of conduit, and produce a neat, square, well-supported installation.

Answer viva questions on testing sequence, protective-device selection and documentation without prompts.

Apply good workmanship standards to cable routing, labelling and enclosure sealing, and self-inspect against a checklist.

Practise safe tool handling and housekeeping under timed conditions.

Produce a full set of documentation for one installation: schedule of circuits, test certificate and as-installed drawing.

Complete two full-length mock exams under timed conditions and review every wrong answer to its source topic.

Re-derive the ten most-missed formulas and safety rules from memory and check them against notes.

State the documentation and notification requirements that apply before and after an installation is energised.
