Basic Home Electrical Course

Lesson 1 • Electrical Hazards and Shock Prevention

Identifies shock, arc flash, and fire risks in residential settings. Builds the habit of hazard recognition before any hands-on task.

Lesson 2 • How Electricity Works

Covers voltage, current, resistance, and Ohm's Law as the foundation of all electrical work. Connects atomic theory to practical circuit behaviour.

Lesson 3 • Lockout and Tagout Procedures

Teaches de-energisation, lockout, and verification steps to prevent accidental re-energisation. Directly supports safe work on any home circuit.

Lesson 4 • Personal Protective Equipment for Electricians

Specifies PPE selection, inspection, and use for home electrical tasks. Reinforces that proper gear is the first line of defence against injury.

Lesson 1 • Residential Wire Types and Ratings

Identifies NM cable, THHN, UF cable, and armoured cable by application and ampacity. Correct wire selection prevents overheating and code violations.

Lesson 2 • Reading Wire Labels and Markings

Decodes insulation colour codes, conductor markings, and cable jacket printing. Accurate identification prevents miswiring and safety incidents.

Lesson 3 • Connectors, Boxes, and Fittings

Covers wire nuts, push-in connectors, electrical boxes, and conduit fittings. Proper hardware selection ensures secure, code-compliant connections.

Lesson 4 • Essential Hand Tools for Electrical Work

Covers screwdrivers, pliers, wire strippers, and fish tape used daily on residential jobs. Proper grip and technique reduce injury and damage.

Lesson 1 • Main Electrical Panel Anatomy

Identifies main breaker, bus bars, neutral bar, and earth bar inside the panel. Understanding panel layout is essential for safe breaker and circuit work.

Lesson 2 • Branch Circuits and Circuit Ratings

Defines general-purpose, dedicated, and small-appliance circuits with their ampacity requirements. Correct circuit assignment prevents overloads and code violations.

Lesson 3 • Utility Service and Meter Base

Explains how utility power enters the home through the service drop, meter, and service entrance conductors. Establishes the boundary between utility and homeowner responsibility.

Lesson 4 • Earthing and Bonding Systems

Distinguishes earthing from bonding and explains their roles in fault protection. Proper earthing is mandatory for safe operation of all home circuits.

Lesson 1 • Replacing and Upgrading Breakers

Guides safe breaker replacement, brand compatibility, and tandem breaker rules. Correct replacement maintains panel integrity and code compliance.

Lesson 2 • AFCI Protection: Devices and Placement

Explains arc-fault detection technology and required bedroom and living-area locations. AFCI protection addresses the leading cause of residential electrical fires.

Lesson 3 • Identifying and Resetting Tripped Breakers

Teaches the correct reset procedure and root-cause investigation before restoring power. Resetting without diagnosis risks repeated trips and fire.

Lesson 4 • How Circuit Breakers Operate

Explains thermal-magnetic and electronic trip mechanisms that protect circuits from overload and short circuit. Understanding operation guides accurate diagnosis.

Lesson 1 • Single-Pole and Three-Way Switches

Teaches switch leg wiring, traveller wire routing, and common terminal identification for single-pole and three-way configurations. Three-way wiring enables control from two locations.

Lesson 2 • Wiring Standard Duplex Receptacles

Covers terminal identification, wire connection sequence, and box mounting for 15A and 20A receptacles. Correct polarity and earthing are non-negotiable safety requirements.

Lesson 3 • Dimmer Switches and Smart Switches

Covers dimmer load ratings, neutral wire requirements, and smart switch pairing. Compatibility between switch and load type prevents flicker and failure.

Lesson 4 • Specialty Receptacles and Configurations

Addresses USB, 20A T-slot, 240V, and split-wired receptacles for specific applications. Specialty devices require precise wiring to function safely.

Lesson 1 • Pulling Wire Through Conduit

Addresses wire lubrication, pull string use, conductor fill limits, and pulling tension. Proper technique prevents insulation damage during installation.

Lesson 2 • PVC Conduit Installation

Covers PVC cutting, solvent welding, expansion fitting use, and burial depth requirements. PVC is preferred for underground and corrosive environments.

Lesson 3 • Fishing Wire Through Finished Walls

Covers fish tape, glow rods, and magnetic fishing tools for adding circuits without opening walls. Minimally invasive techniques preserve finished surfaces.

Lesson 4 • Planning Wire Routes in a Home

Teaches route selection through walls, ceilings, and floors while avoiding structural members and other utilities. Good planning minimises damage and rework.

Lesson 1 • Dead Outlets and Open Circuits

Diagnoses tripped GFCI upstream, loose connections, and open neutrals causing dead receptacles. Tracing the circuit from load to source finds the fault efficiently.

Lesson 2 • Diagnosing Faulty Switches and Fixtures

Tests switches, sockets, and fixture wiring to isolate device failure from wiring faults. Accurate device testing avoids unnecessary replacement of good components.

Lesson 3 • Systematic Troubleshooting Methodology

Introduces a structured symptom-to-cause diagnostic process applicable to any electrical fault. Systematic thinking reduces guesswork and repair time.

Lesson 4 • Repeatedly Tripping Breakers

Differentiates overload, short circuit, and earth fault as causes of repeated breaker trips. Each cause requires a distinct diagnostic and repair approach.

Lesson 1 • Bathroom and Kitchen Electrical Upgrades

Applies small-appliance circuit rules, GFCI placement, and exhaust fan wiring in high-use areas. These rooms have the strictest residential wiring requirements.

Lesson 2 • Adding a New Outlet or Circuit

Walks through planning, permitting, wiring, and testing a new branch circuit from panel to outlet. This project integrates panel work, wire routing, and device installation.

Lesson 3 • Upgrading an Electrical Panel

Covers panel sizing, permit process, service upgrade coordination, and circuit transfer. Panel upgrades require careful planning and utility coordination.

Lesson 4 • EV Charger and Large Appliance Circuits

Guides 240V dedicated circuit installation for EV chargers, dryers, and ranges. High-amperage circuits demand precise wire sizing and connection torque.
