What the Fault Finding and Protective Devices N5 Question papers cover
- Fault finding principles: systematic testing methods, logical fault sequences, safety rules before and during testing.
- Test equipment: multimeters, insulation testers, continuity testers, clamp meters, and fault locators.
- Common electrical faults: open circuits, short circuits, earth faults, overloads, unbalanced loads, and overheating.
- Protective devices: fuses, miniature circuit breakers (MCBs), earth leakage units, surge protectors, relays, and thermal devices.
- Motor and machine protection: starters, overload relays, contactors, and emergency stops.
- Distribution boards: correct labelling, selection of protection ratings, and discrimination between devices.
- Troubleshooting techniques: step-by-step isolation, identifying symptoms, testing components, and confirming the repair.
- Safety compliance: lock-out/tag-out, correct PPE, SANS wiring codes, and risk assessment before repair.
How to approach these papers
- Begin every fault-finding answer with a safety step (isolation, lock-out, test for dead).
- In fault diagnosis, describe the symptom, likely cause, test performed, and conclusion.
- When asked about protective devices, state the principle, application, and one advantage or limitation.
- Draw neat diagrams of distribution boards or motor circuits and clearly label protective devices.
- In calculation questions (fuse size, breaker rating, cable sizing), show formula, substitute values, and provide units.
