Plumbing & Electrics
You install a complete plumbing system on a sample wall – from source supply to header tank, hot and cold shower system, sink, toilet and drainage. You study pipe types, trap seals, water supply systems, faucets, valves, sewage and common faults. On the electrical side, you start with the fundamentals – voltage, amperage, resistance, wattage, earthing and safety. You study how electricity is generated and distributed, including solar energy systems. You wire seven practical circuits from simple single-light setups through to two-way switches and combination circuits, and learn to read wiring diagrams, test systems and fault-find. Most people call a plumber or an electrician. You will understand what both of them do.
