Lesson 4 • Basic Electrical Theory

Covers atomic structure, electron flow, and Ohm's Law as the foundation of all electrical work. Establishes the quantitative relationships technicians use daily.

Lesson 1 • Hand Tools for Electrical Work

Covers selection, safe use, and maintenance of insulated hand tools. Proper tool handling reduces injury risk and improves work quality throughout the course.

Lesson 2 • Multimeters and Voltage Testers

Teaches measurement of voltage, current, resistance, and continuity using digital multimeters. These skills are applied in every diagnostic and installation task in later chapters.

Lesson 3 • Power Tools and Drilling Equipment

Addresses safe operation of drills, hole saws, and reciprocating saws for electrical installation. Correct technique prevents structural damage and personal injury.

Lesson 1 • Conduit Systems and Bending

Teaches installation of rigid, intermediate, and flexible conduit systems including accurate bending techniques. Conduit work is a core field skill required in commercial and industrial settings.

Lesson 2 • Conductor Types and Sizing

Covers wire materials, insulation ratings, and ampacity tables for proper conductor selection. Correct sizing prevents overheating and ensures code-compliant installations.

Lesson 3 • Boxes, Enclosures, and Fill Calculations

Addresses selection, mounting, and fill calculations for outlet, junction, and pull boxes. Proper box sizing prevents overcrowding and heat buildup in completed installations.

Lesson 4 • Cable Types and Applications

Identifies nonmetallic sheathed, armored, and service entrance cables and their appropriate uses. Matching cable type to environment ensures durability and code compliance.

Lesson 1 • Ground Fault and Arc Fault Protection

Addresses GFCI and AFCI protection requirements, operating principles, and testing procedures. These devices are critical life-safety and fire-prevention tools in modern installations.

Lesson 2 • Power Quality Correction Methods

Covers surge protection, power conditioning, UPS systems, and harmonic filters. Applying these solutions protects sensitive equipment and improves system efficiency.

Lesson 3 • Bonding Requirements and Methods

Covers bonding of metal piping, structural steel, and service equipment to eliminate voltage differences. Proper bonding prevents shock hazards from stray voltages in buildings.

Lesson 4 • Power Quality Fundamentals

Identifies voltage sags, swells, harmonics, and transients that degrade equipment performance. Understanding power quality issues prepares students to diagnose and resolve them.

Lesson 1 • Receptacles, Switches, and Fixtures

Covers installation and testing of outlets, switches, GFCI, AFCI devices, and lighting fixtures. These finish-work skills complete the visible portion of a residential installation.

Lesson 2 • Smoke, CO, and Low-Voltage Systems

Addresses placement, interconnection, and testing of life-safety and low-voltage systems in homes. These systems are required by code and critical to occupant safety.

Lesson 3 • Residential Load Calculations

Applies standard load calculation methods to size service panels and feeders for dwellings. Accurate load calculations prevent undersized services and nuisance tripping.

Lesson 4 • Residential Service Entrance

Covers service drop, meter base, and main panel installation for residential buildings. Understanding service entrance is essential before wiring any branch circuits.

Lesson 1 • Commercial Service and Distribution

Covers utility service entrance, transformers, and main switchgear for commercial buildings. Distribution system design determines how power reaches every downstream load.

Lesson 2 • Three-Phase Power Systems

Introduces wye and delta configurations, phase relationships, and three-phase load balancing. Three-phase knowledge is essential for commercial and industrial electrical work.

Lesson 3 • Commercial Lighting Systems

Covers fluorescent, LED, and HID lighting systems including ballasts, drivers, and controls. Lighting represents a major portion of commercial electrical installation work.

Lesson 4 • Panelboards and Overcurrent Protection

Teaches panelboard installation, breaker selection, and coordination of overcurrent protective devices. Proper protection prevents equipment damage and ensures selective fault clearing.

Lesson 1 • Motor Protection Devices

Addresses overload relays, thermal protection, and phase-loss monitoring for motor safety. Proper protection extends motor life and prevents costly burnouts.

Lesson 2 • Control Circuit Diagrams and Wiring

Develops ability to read ladder diagrams and wire control circuits including start-stop and jog functions. Diagram reading is the core skill for motor control troubleshooting.

Lesson 3 • Variable Frequency Drives

Introduces VFD operating principles, parameter programming, and installation requirements. VFDs are widely used for energy savings and process control in modern facilities.

Lesson 4 • AC Motor Fundamentals

Covers induction motor construction, operating principles, and nameplate data interpretation. Motor fundamentals are the foundation for all control and protection topics that follow.

Lesson 1 • Documentation and Repair Reporting

Teaches creation of fault reports, repair logs, and as-built markup documentation. Accurate records support future maintenance, warranty claims, and regulatory inspections.

Lesson 2 • Troubleshooting Overcurrent Devices

Addresses diagnosis of nuisance tripping, failed breakers, and blown fuses in distribution systems. Correct diagnosis prevents unnecessary device replacement and identifies root causes.

Lesson 3 • Systematic Troubleshooting Methodology

Introduces a structured fault-finding process using observation, measurement, and elimination. A repeatable method reduces diagnostic time and prevents misdiagnosis on the job.

Lesson 4 • Diagnosing Wiring and Connection Faults

Covers detection of open circuits, short circuits, ground faults, and high-resistance connections. Wiring faults are the most common cause of electrical failures in the field.
