DIY Electrician Course

Lesson 1 • Electrical Hazards and Shock Prevention

Identifies causes of electrocution, arc flash, and fire. Learners learn to recognise dangerous conditions before touching any wiring.

Lesson 2 • Residential Electrical Codes Overview

Introduces permit requirements, inspection processes, and code compliance concepts. Learners understand the regulatory framework governing every project in this course.

Lesson 3 • Lockout and Tagout Procedures

Teaches de-energisation and verification steps before any work begins. Proper lockout/tagout prevents accidental re-energisation throughout all hands-on chapters.

Lesson 4 • Personal Protective Equipment for Electricians

Specifies PPE selection and proper use for DIY electrical tasks. Connects safety gear choices directly to the hazard types identified in the previous section.

Lesson 1 • Understanding the Main Service Panel

Maps panel components including the main breaker, bus bars, neutral bar, and earth bar. Learners gain the panel literacy needed to add and troubleshoot circuits.

Lesson 2 • Circuit Breakers and Fuses

Explains breaker types, trip ratings, and fuse sizing. Correct overcurrent protection selection is required before installing any new circuit.

Lesson 3 • Essential Electrician's Hand Tools

Covers wire strippers, needle-nose pliers, fish tape, and testers. Proper tool selection prevents damage to conductors and speeds up every task ahead.

Lesson 4 • Wire Types, Gauges, and Ratings

Explains NM cable, THHN, and armoured cable along with ampacity charts. Correct wire selection is mandatory for every circuit installation covered later.

Lesson 1 • Earthing and Bonding Conductors

Distinguishes earthing from bonding and explains their protective roles. Proper earth paths are required in every device and panel connection covered ahead.

Lesson 2 • Working Inside Electrical Boxes

Covers wire folding, device seating, and box fill compliance. Neat box work prevents insulation damage and ensures devices seat flush and function correctly.

Lesson 3 • Terminating at Devices and Terminals

Explains screw terminal, back-stab, and lug connections for outlets, switches, and panels. Correct termination prevents loose connections that cause arcing and fires.

Lesson 4 • Wire Nut and Push-In Connector Splices

Covers wire nut sizing, twist technique, and push-in connector limits. Learners learn which connector type suits each application before moving to device wiring.

Lesson 1 • Ceiling Fixtures and Ceiling Fans

Explains fan-rated box requirements, weight limits, and dual-switch wiring. Proper mounting and wiring prevent fixture failure and eliminate shock hazards.

Lesson 2 • Single-Pole and Three-Way Switches

Teaches switch loop wiring, traveller wires, and common terminal identification. Three-way switch wiring is the most requested DIY skill after outlet replacement.

Lesson 3 • Dimmer and Smart Switch Installation

Covers dimmer load ratings, neutral wire requirements, and smart switch pairing. Learners upgrade standard switches without overloading dimmers or losing functionality.

Lesson 4 • GFCI and AFCI Outlet Installation

Explains GFCI load-side protection and AFCI outlet placement requirements. These devices are code-required in kitchens, bathrooms, and other specified locations.

Lesson 1 • Circuit Planning and Load Calculations

Covers load estimation, circuit sizing, and panel capacity checks. Accurate planning prevents overloaded circuits and failed inspections on new installations.

Lesson 2 • Connecting New Circuits at the Panel

Covers breaker installation, conductor landing, and torque specifications. Learners energise new circuits safely after confirming all rough-in work is complete.

Lesson 3 • Stapling, Securing, and Protecting Cable

Explains staple spacing, cable support intervals, and conduit protection zones. Proper securing satisfies code requirements and prevents cable sag and abrasion.

Lesson 4 • Pulling Cable Through Walls and Ceilings

Covers fish tape use, cable fishing techniques, and pulling through insulation. Efficient cable routing reduces installation time and avoids damage to existing finishes.

Lesson 1 • Bathroom Outlet and Lighting Circuits

Explains GFCI placement, dedicated bathroom circuit rules, and vanity lighting wiring. Bathroom code requirements differ from general living spaces in several key ways.

Lesson 2 • Exhaust Fan and Ventilation Wiring

Covers fan-only, fan-light, and humidity-sensing fan wiring configurations. Proper ventilation wiring prevents moisture damage and satisfies code in wet areas.

Lesson 3 • Kitchen Circuit Requirements

Covers small-appliance circuits, refrigerator circuits, and counter outlet spacing rules. Kitchen wiring has the highest circuit density of any room in a residence.

Lesson 4 • Dishwasher and Disposal Circuits

Explains dedicated circuit sizing, switch-controlled disposal wiring, and junction box placement. These circuits require specific ampacity and switching configurations.

Lesson 1 • Geyser and HVAC Wiring

Explains 240V geyser connections, disconnect requirements, and air handler wiring. Proper disconnect placement is a code requirement for all fixed appliances.

Lesson 2 • Installing a Subpanel

Teaches feeder sizing, four-wire feeder installation, and subpanel earthing and bonding rules. A subpanel extends capacity to garages, workshops, or additions.

Lesson 3 • Dryer and Washer Circuit Installation

Covers 30A dryer circuit wiring, four-wire connections, and dryer outlet types. Learners also wire a dedicated 20A washer circuit with GFCI protection.

Lesson 4 • 240V Circuit Fundamentals

Explains two hot legs, split-phase power, and how 240V differs from 120V circuits. This foundation is required before wiring any high-voltage appliance in this chapter.

Lesson 1 • Diagnosing Dead Outlets and Circuits

Explains tripped breakers, tripped GFCI devices, and open neutral faults. Learners follow a logical sequence to restore power without replacing functional components.

Lesson 2 • Using a Multimeter Effectively

Covers voltage, electrical continuity, and resistance measurement techniques for residential circuits. Multimeter proficiency is the core diagnostic skill for every fault scenario ahead.

Lesson 3 • Interpreting Inspection Failures and Corrections

Reviews common inspection rejection reasons and the corrective actions required. Learners learn to self-audit work before the inspector arrives to avoid re-inspection fees.

Lesson 4 • Troubleshooting Switches and Fixtures

Diagnoses failed switches, flickering lights, and buzzing dimmers using voltage and electrical continuity tests. These are the most frequent service calls in residential electrical work.
