Home Electrician Course

4.2

Stop paying an electrician for every outlet, switch, or circuit problem in your home. This course gives you the hands-on knowledge to handle real residential electrical work safely and correctly, from reading wiring diagrams to installing 240-volt appliance circuits. Learn what the pros know and get the job done right the first time.

Dedika for students

What your team will master:

You will learn how residential electrical systems work from the service connection all the way to individual outlets and fixtures. The course covers electrical safety, tool selection, wire sizing, and code requirements so every installation you complete is safe and inspection-ready. You will wire receptacles, switches, ceiling fans, and recessed lights, then move on to 240-volt circuits for major appliances. Troubleshooting chapters teach you to diagnose tripped circuit breakers, dead outlets, flickering lights, and earth faults using a multimeter and a step-by-step method. Supplementary sections cover EV charger installation, smart switches, generator transfer switches, and low voltage (LV) data wiring.

Course content

8 Chapters • 33 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Electrical Safety and Fundamentals

  • Lesson 1 • Core Electrical Theory

    Introduces voltage, current, resistance, and power using Ohm's Law. Provides the mathematical foundation needed to size conductors and circuit breakers later.

  • Lesson 2 • Reading Electrical Diagrams

    Teaches standard schematic symbols and simple wiring diagrams. Students can interpret diagrams before beginning any installation work.

  • Lesson 3 • Electrical Hazards and Risk Awareness

    Covers shock, arc flash, and fire risks in residential settings. Builds the safety mindset that underpins every subsequent hands-on task.

  • Lesson 4 • Personal Protective Equipment

    Teaches selection and correct use of PPE for home electrical work. Connects directly to hazard types identified in the previous section.

Chapter 2See details

Tools, Materials, and Codes

  • Lesson 1 • Residential Code Concepts

    Translates key residential wiring code requirements into practical rules for box fill, circuit spacing, and GFCI placement. Compliance knowledge guides every installation decision.

  • Lesson 2 • Wire Types and Conductor Sizing

    Explains AWG sizing, insulation ratings, and common cable types such as NM and armoured cable. Correct sizing prevents overheating and code violations.

  • Lesson 3 • Hand Tools for Electrical Work

    Covers screwdrivers, pliers, wire strippers, and fish tapes used daily. Proper tool selection prevents damage to conductors and devices.

  • Lesson 4 • Test and Measurement Instruments

    Introduces multimeters, non-contact voltage testers, and circuit tracers. Accurate measurement is essential for safe troubleshooting covered in later chapters.

Chapter 3See details

The Home Electrical System

  • Lesson 1 • Branch Circuit Organisation

    Teaches how to map, label, and load-balance branch circuits throughout a home. Proper organisation simplifies troubleshooting and future upgrades.

  • Lesson 2 • Main Panel and Subpanels

    Covers panel anatomy, bus bars, neutral and ground separation, and subpanel feeders. Students can safely identify live versus de-energised components inside a panel.

  • Lesson 3 • Earthing and Equipotential Bonding

    Distinguishes earthing from bonding and explains their roles in fault protection. Correct earthing is required before any outlet or device installation.

  • Lesson 4 • Service Entrance and Meter

    Explains how utility power enters the home through the service drop, meter, and main disconnect. Establishes the starting point of every residential circuit.

Chapter 4See details

Wiring Methods and Rough-In

  • Lesson 1 • Running Cable in Walls and Ceilings

    Covers drilling, notching, and protecting cable through framing members. Proper routing prevents physical damage and meets code stapling requirements.

  • Lesson 2 • Conduit Installation Basics

    Introduces EMT and PVC conduit bending, coupling, and pulling wire. Conduit is required in exposed locations and garages.

  • Lesson 3 • Electrical Box Selection and Mounting

    Explains box types, cubic-inch ratings, and mounting methods for new and retrofit work. Correct box selection is the foundation of every device installation.

  • Lesson 4 • Fishing Wire in Existing Walls

    Teaches techniques for adding circuits in finished walls without major demolition. Students use fish tape, flex bits, and inspection cameras effectively.

Chapter 5See details

Outlets, Switches, and Devices

  • Lesson 1 • Standard Receptacle Installation

    Covers duplex receptacle wiring, polarity, and earthing in end-of-run and middle-of-run positions. Correct polarity prevents shock and appliance damage.

  • Lesson 2 • Single-Pole and Three-Way Switches

    Teaches switch leg wiring for single-pole and three-way configurations controlling one fixture. Three-way wiring is the most common multi-switch challenge in homes.

  • Lesson 3 • GFCI and AFCI Receptacles

    Explains how GFCI and AFCI devices detect faults and where each is required. Students wire both device types and test them for proper operation.

  • Lesson 4 • Specialty Devices and Dimmers

    Covers dimmer compatibility, USB receptacles, and combination switch-outlet devices. Students select and install devices matched to load type and box space.

Chapter 6See details

Lighting Installation and Fixtures

  • Lesson 1 • Ceiling Fan Installation

    Teaches fan-rated box installation, blade balance, and dual-switch or remote wiring. Incorrect box use is the leading cause of ceiling fan failures.

  • Lesson 2 • Under-Cabinet and Accent Lighting

    Covers hardwired LED strip and puck light installation in kitchens and display areas. Students conceal wiring and connect to switched circuits cleanly.

  • Lesson 3 • Recessed Lighting Installation

    Explains IC versus non-IC housings, remodel cans, and trim selection for recessed lights. Proper housing choice prevents insulation contact fires.

  • Lesson 4 • Ceiling Fixture Wiring and Mounting

    Covers junction box ratings, mounting brackets, and wire connections for standard ceiling fixtures. Box rating must match fixture weight before installation begins.

Chapter 7See details

Appliance and High-Voltage Circuits

  • Lesson 1 • Electric Range and Oven Circuits

    Covers 50-amp circuit installation, range receptacle types, and direct-wire connections. Students distinguish three-wire legacy wiring from four-wire current code.

  • Lesson 2 • Dryer and Water Heater Circuits

    Teaches 30-amp dryer and 30-amp water heater circuit wiring with correct terminations. Both appliances require dedicated circuits and specific receptacle or direct-wire methods.

  • Lesson 3 • HVAC Disconnect and Condensing Unit

    Explains fused disconnect installation, condenser wiring, and minimum circuit ampacity labels. Students read equipment nameplates to select correct overcurrent protection.

  • Lesson 4 • 240-Volt Circuit Fundamentals

    Explains two-pole circuit breaker operation, hot-hot-neutral-ground wiring, and voltage measurement. Understanding dual-phase power is prerequisite to all appliance wiring.

Chapter 8See details

Troubleshooting and Circuit Repair

    Covers testing for open neutrals, broken conductors, and tripped GFCI upstream. Students trace a dead outlet back to its source efficiently.

  • Lesson 2 • Ground Faults and Short Circuits

    Explains how to locate ground faults and short circuits using isolation and resistance testing. Students clear faults without damaging equipment or creating new hazards.

  • Lesson 3 • Circuit Breaker and Overload Problems

    Teaches how to identify nuisance tripping, overloaded circuits, and failed circuit breakers. Students calculate load and determine whether a circuit upgrade is needed.

  • Lesson 4 • Systematic Troubleshooting Approach

    Introduces a structured fault-finding process: observe, isolate, test, repair, verify. A repeatable method reduces diagnostic time and prevents misdiagnosis.
