Domestic Electrician Course

Lesson 1 • Electrical Hazards and Risk Assessment

Identifies shock, arc flash, and fire risks common in domestic installations. Connects hazard recognition to safe working decisions throughout the course.

Lesson 2 • Safe Isolation Procedures

Teaches the full safe isolation sequence to de-energise circuits before work begins. Prevents accidental energisation, a leading cause of electrical injury.

Lesson 3 • Basic Electrical Theory

Covers voltage, current, resistance, and Ohm's Law as applied to domestic circuits. Establishes the theoretical base for all subsequent practical work.

Lesson 1 • Hand Tools for Electrical Work

Covers screwdrivers, pliers, cable strippers, and drilling equipment used daily on site. Correct tool selection prevents damage to conductors and fittings.

Lesson 2 • Test Instruments and Their Use

Introduces multimeters, voltage indicators, and continuity testers used throughout installation and verification. Accurate instrument use underpins safe and compliant work.

Lesson 3 • Wiring Enclosures and Containment

Covers conduit, trunking, and cable tray systems used to protect and route domestic wiring. Proper containment prevents mechanical damage and supports neat, compliant installations.

Lesson 1 • Earthing and Bonding Systems

Covers TN-S, TN-C-S, and TT earthing arrangements and their bonding requirements. Correct earthing protects occupants from fault voltages throughout the installation.

Lesson 2 • Circuit Identification and Documentation

Teaches labelling, circuit schedules, and as-installed drawing conventions. Accurate documentation supports safe maintenance and future alterations.

Lesson 3 • Consumer Units and Circuit Protection

Examines consumer unit layout, MCB ratings, and RCD protection requirements. Students can select appropriate protective devices for each domestic circuit type.

Lesson 1 • Intermediate and Multi-Location Switching

Extends two-way switching to intermediate configurations for stairways and long corridors. Reinforces conductor identification and correct terminal connections.

Lesson 2 • Luminaire and Fitting Installation

Covers mounting, connecting, and securing ceiling roses, pendants, downlights, and batten holders. Correct mechanical fixing prevents luminaire failure and fire risk.

Lesson 3 • Dimmer and Specialist Switch Wiring

Addresses dimmer compatibility, occupancy sensors, and smart switch wiring for modern homes. Builds on basic switching skills to meet contemporary client expectations.

Lesson 4 • One-Way and Two-Way Switching

Explains wiring methods for standard and two-way switching using loop-in and junction-box methods. Students can select the most efficient method for each installation scenario.

Lesson 1 • Ring Final Circuit Theory

Explains the ring topology, current sharing, and floor area limits for ring final circuits. Understanding the theory prevents overloading and non-compliant installations.

Lesson 2 • Socket Outlet Installation

Covers mounting heights, back-box fixing, and terminal connections for standard and USB outlets. Correct installation ensures mechanical security and safe contact pressure.

Lesson 3 • Radial Circuit Design and Installation

Covers 20 A and 32 A radial circuits for kitchens, garages, and dedicated appliances. Radial design skills complement ring circuit knowledge for full domestic coverage.

Lesson 1 • EV Charging Point Installation

Covers dedicated EV charger circuits, earthing requirements, and protective device selection. EV charging is a rapidly growing domestic installation requirement.

Lesson 2 • Electric Shower Circuit Wiring

Addresses shower circuit sizing, RCD protection, and bathroom zone compliance for electric showers. Correct installation prevents shock risk in the most hazardous domestic location.

Lesson 3 • Boiler and Heating Control Wiring

Explains boiler supply, programmer, thermostat, and zone valve wiring for central heating systems. Correct control wiring ensures safe and efficient heating operation.

Lesson 4 • Bathroom and Special Location Wiring

Applies zone rules, IP ratings, and supplementary bonding requirements to bathroom installations. Special location rules reduce shock risk where water and electricity coexist.

Lesson 1 • Earth Fault Loop Impedance Testing

Covers Ze and Zs measurements and their relationship to protective device disconnection times. Correct loop impedance ensures automatic disconnection under fault conditions.

Lesson 2 • Visual Inspection Procedures

Covers pre-test visual checks for correct connections, polarity, and mechanical integrity. Visual inspection catches defects before energisation and reduces test failures.

Lesson 3 • Continuity and Polarity Testing

Teaches continuity testing of protective conductors, ring circuits, and bonding connections. Confirms circuit integrity before insulation resistance and live testing.

Lesson 4 • Insulation Resistance Testing

Explains insulation resistance test voltages, pass values, and precautions for sensitive equipment. Detects insulation breakdown that could cause shock or fire.

Lesson 1 • Electrical Installation Certificates

Covers completion of Electrical Installation Certificates and Minor Works Certificates for new and altered circuits. Accurate certification is a legal requirement for all notifiable work.

Lesson 2 • Regulatory Framework for Domestic Work

Explains the regulatory requirements governing domestic electrical installation and notification obligations. Understanding the framework prevents legal liability and protects clients.

Lesson 3 • Client Handover and Aftercare

Covers demonstration of installed systems, provision of documentation, and client safety briefing. Professional handover builds client confidence and reduces callback visits.
