gh-ctvet-cert-ii-electrical · Work through your exam, one topic at a time.
The Ghana CTVET Certificate II in Electrical Engineering is a competency-based TVET qualification for people starting or formalising a career as an electrical artisan. It sits at the foundation level of the TVET ladder and is typically pursued through a technical institute or an approved apprenticeship pathway, with assessment against occupational standards rather than a purely academic syllabus. The gh-ctvet-cert-ii-electrical study guide has 8 sections and about 3,672 words.
01Occupational Health, Safety and Environment
The Occupational Health, Safety and Environment domain tests whether you can work on and around electrical installations without injuring yourself, colleagues or the public, and without damaging the environment. Questions cover hazard and risk, the hierarchy of controls, safe isolation, PPE, emergency response, fire, waste handling and the Ghanaian legal framework behind them.
417 words, about 2 min02Electrical Principles and Circuit Theory
Electrical Principles and Circuit Theory tests the calculations and concepts that underpin every later topic: Ohm's law, power, series and parallel networks, Kirchhoff's laws, alternating current, impedance and three-phase relationships. Expect short numerical questions and questions asking you to predict what happens to current or voltage when a component changes.
440 words, about 2 min03Electrical Materials
Electrical Materials tests your ability to choose and handle conductors, insulation, cables, accessories and devices correctly. Questions cover copper versus aluminium, PVC versus XLPE, cable construction and selection, terminations, and how material properties set current ratings and voltage drop.
427 words, about 2 min04Tools and Test Instruments
Tools and Test Instruments tests safe selection, use, checking and interpretation of hand tools and electrical test equipment. Questions cover insulated tools, proving units, multifunction testers, insulation resistance, continuity, loop impedance, RCD testing, calibration and recording results.
369 words, about 2 min05Wiring Systems and Installation Practice
Wiring Systems and Installation Practice tests how you choose and install a wiring method that is safe, compliant and suited to the building. Questions cover conduit and trunking, cable routing and support, derating factors, segregation, special locations, accessories and workmanship standards.
432 words, about 2 min06Electrical Machines and Transformers
Electrical Machines and Transformers tests the construction, operating principle, starting and protection of transformers, DC machines and AC motors. Questions cover turns ratio, losses and efficiency, synchronous speed and slip, starting methods, motor protection and nameplate data.
387 words, about 2 min07Protection, Earthing and Fault Diagnosis
Protection, Earthing and Fault Diagnosis tests how circuits are protected against overload, short circuit and earth fault, how earthing systems achieve disconnection, and how faults are traced systematically. Questions cover device types and ratings, RCDs, TN-S, TN-C-S and TT systems, bonding, loop impedance and test limits.
467 words, about 2 min08Electrical Drawing, Wiring Diagrams and Documentation
Electrical Drawing, Wiring Diagrams and Documentation tests your ability to read, interpret and produce installation information. Questions cover drawing types, standard symbols, title blocks and revisions, single-line diagrams, cable schedules, test certificates and handover documents.
