To give you a taste of what a high-quality contains, here are three typical questions:
The total exam is for , broken down as follows:
(approximately 40 marks), typically requiring candidates to prepare single-line diagrams (SLD) or perform specific calculations. Candidates generally have 2 to 4 hours to complete the exam. Passing Score: A minimum of is typically required to pass. Key Topics Covered Exam questions are drawn heavily from the SEWA Electrical Installation Regulations . Core topics include: Wiring Regulations: This guide breaks down the exam structure, key
: Familiarity with terms like ELR (Earth Leakage Relay), CBCT (Core Balance Current Transformer), and SWA (Steel Wire Armoured) cables. Required Tests
Cable specifications: Standard sizes for cables and their corresponding Earth Continuity Conductor (ECC) sizes. Minimum underground cable laying depths. Power Protection & Distribution: Understanding MDBs , SMDBs , and DBs .
: High ambient soil temperatures reduce the rate of heat dissipation from the cable conductors. If the cable carries its full rated current under these conditions, the insulation temperature will exceed its maximum limit (e.g., 90°C for XLPE), causing premature insulation failure or thermal runaway. Question 3: Protection Coordination
