Building Electrical Installation Course

Lesson 1 • First Aid for Electrical Incidents

Trains immediate response to electric shock, burns, and cardiac arrest caused by electrical contact. Reinforces safety culture established throughout the chapter.

Lesson 2 • Electrical Hazards and Risk Assessment

Identifies shock, arc flash, and fire hazards common in building installations. Teaches systematic risk assessment before any live-work activity.

Lesson 3 • Personal Protective Equipment and Lockout

Specifies PPE selection and lockout/tagout procedures for electrical work. Ensures learners can isolate circuits safely before installation begins.

Lesson 4 • Regulatory Framework and Codes

Introduces the structure of electrical installation standards and inspection requirements. Learners understand compliance obligations without referencing jurisdiction-specific code numbers.

Lesson 1 • Conduit and Cable Management Systems

Covers rigid metal, PVC, and flexible conduit along with cable trays and raceways. Learners select the appropriate system based on environment and load.

Lesson 2 • Conductors and Insulation Types

Examines copper and aluminium conductors, insulation ratings, and temperature limits. Connects material properties to safe current-carrying capacity.

Lesson 3 • Material Storage and Handling

Establishes best practices for storing conductors, conduit, and devices on a job site. Prevents material damage that leads to installation defects.

Lesson 4 • Wiring Devices and Fittings

Identifies outlets, switches, connectors, and junction boxes used in building wiring. Proper fitting selection prevents loose connections and overheating.

Lesson 1 • Electrical Drawing Conventions

Explains standard symbols, line types, and title block information used in electrical drawings. Accurate symbol recognition is prerequisite to all plan reading.

Lesson 2 • Specifications and Material Schedules

Interprets written specifications and equipment schedules that govern material quality and installation methods. Specifications override drawings when conflicts arise.

Lesson 3 • Quantity Takeoff and Material Estimation

Applies drawing data to calculate conduit lengths, conductor quantities, and device counts. Accurate takeoffs prevent material shortages and cost overruns.

Lesson 4 • Single-Line and Schematic Diagrams

Teaches interpretation of single-line diagrams showing power distribution and schematic control circuits. Learners trace power flow from source to load.

Lesson 1 • Branch Circuit Wiring for Receptacles

Installs 15 A and 20 A general-purpose and dedicated receptacle circuits from panel to device. Learners apply box fill and circuit loading rules.

Lesson 2 • Conduit Bending Techniques

Covers stub-up, offset, saddle, and back-to-back bends using hand and mechanical benders. Accurate bending eliminates conductor damage and failed inspections.

Lesson 3 • Switch and Lighting Circuit Wiring

Wires single-pole, three-way, and four-way switch configurations for interior lighting. Connects switching logic to schematic diagrams from Chapter 3.

Lesson 4 • Conductor Pulling and Termination

Demonstrates wire-pulling calculations, lubricant use, and proper termination torque. Correct termination prevents overheating and connection failure.

Lesson 1 • GFCI and AFCI Protection Applications

Identifies locations requiring ground fault and arc fault circuit interrupter protection and installs devices correctly. Testing confirms proper operation before occupancy.

Lesson 2 • Equipment Earthing and Bonding

Establishes equipment earthing conductor paths and bonding of metallic systems. A low-impedance fault path ensures overcurrent devices operate quickly.

Lesson 3 • Earthing Electrode Systems

Installs earth rods, concrete-encased electrodes, and water pipe earths as part of the earthing electrode system. Proper bonding ties all electrodes together.

Lesson 4 • Overcurrent Protection Fundamentals

Explains how fuses and circuit breakers interrupt fault current to protect conductors and equipment. Correct device selection is critical to fire and shock prevention.

Lesson 1 • Load Calculation Methods

Applies standard and optional load calculation methods to determine service and feeder sizes. Accurate load calculations prevent undersized services and nuisance tripping.

Lesson 2 • Feeder and Subpanel Installation

Sizes and installs feeders from main panel to subpanels in multi-unit or large buildings. Proper feeder protection and bonding maintain system integrity.

Lesson 3 • Main Panel Installation and Wiring

Installs main breaker panels including bus connections, neutral bar, and earthing. Correct separation of neutral and earth prevents shock hazards.

Lesson 4 • Metering and Power Quality Monitoring

Introduces revenue metering, current transformers, and basic power quality monitoring equipment. Monitoring data supports energy management and fault diagnosis.

Lesson 1 • Lighting Technology and Selection

Compares LED, fluorescent, and HID lamp technologies by efficacy, colour rendering, and lifespan. Correct lamp selection reduces energy use and maintenance costs.

Lesson 2 • Exterior and Site Lighting

Covers pole-mounted, wall-pack, and pathway lighting installation for parking and building exteriors. Weatherproof wiring methods and photocell controls are emphasised.

Lesson 3 • Lighting Control Systems

Installs occupancy sensors, daylight sensors, and dimming controls to reduce energy consumption. Controls must be compatible with connected lamp and driver types.

Lesson 4 • Interior Lighting Layout and Installation

Applies illuminance calculations to space lighting layouts and installs recessed, surface, and pendant fixtures. Proper support and wiring prevent fixture failures.

Lesson 1 • Fault Diagnosis and Troubleshooting

Applies a structured diagnostic process to locate open circuits, short circuits, and earth faults. Systematic methods reduce downtime and prevent repeat failures.

Lesson 2 • Test Instruments and Their Use

Covers multimeters, clamp meters, insulation testers, and loop impedance testers. Correct instrument selection and connection prevent measurement errors and damage.

Lesson 3 • Energised System Commissioning

Verifies voltage levels, phase rotation, and load balance after energisation. Commissioning confirms the installation meets design specifications before handover.

Lesson 4 • Pre-Energisation Inspection and Testing

Performs continuity, polarity, and insulation resistance tests before applying power. These tests catch wiring errors that would cause faults or equipment damage.
