Basic Home Electrical Course

Lesson 1 • Electrical Hazards and Shock Prevention

This module identifies shock, arc flash, and fire risks in residential settings. It builds the habit of hazard recognition before any hands-on task.

Lesson 2 • How Electricity Works

This module covers voltage, current, resistance, and Ohm's Law as the foundation of all electrical work. It connects atomic theory to practical circuit behavior.

Lesson 3 • Lockout and Tagout Procedures

This module teaches de-energization, lockout, and verification steps to prevent accidental re-energization. It directly supports safe work on any home circuit.

Lesson 4 • Personal Protective Equipment for Electricians

This module specifies PPE selection, inspection, and use for home electrical tasks. It reinforces that proper gear is the first line of defense against injury.

Lesson 1 • Residential Wire Types and Ratings

This topic 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

This topic decodes insulation color codes, conductor markings, and cable jacket printing. Accurate identification prevents miswiring and safety incidents.

Lesson 3 • Connectors, Boxes, and Fittings

This topic 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

This topic 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

This topic identifies main breaker, busbars, neutral bar, and ground bar inside the panel. Understanding panel layout is essential for safe breaker and circuit work.

Lesson 2 • Branch Circuits and Circuit Ratings

This topic 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

This topic explains how utility power enters the home through the service drop, meter, and service entrance conductors. It establishes the boundary between utility and homeowner responsibility.

Lesson 4 • Grounding and Bonding Systems

This topic distinguishes grounding from bonding and explains their roles in fault protection. Proper grounding is mandatory for safe operation of all home circuits.

Lesson 1 • Replacing and Upgrading Breakers

This topic 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

This topic 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

This topic 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

This topic 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

This topic teaches switch leg wiring, traveler 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

This topic covers terminal identification, wire connection sequence, and box mounting for 15A and 20A receptacles. Correct polarity and grounding are non-negotiable safety requirements.

Lesson 3 • Dimmer Switches and Smart Switches

This topic 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

This topic 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

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

Lesson 2 • PVC Conduit Installation

This topic 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

This topic 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

This topic 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

This topic 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

This topic 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

This topic 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

This topic differentiates overload, short circuit, and ground fault as causes of repeated breaker trips. Each cause requires a distinct diagnostic and repair approach.

Lesson 1 • Bathroom and Kitchen Electrical Upgrades

This topic 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

This topic 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

This topic 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

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