Electrical Inspector Certification Prep (ICC/IAEI)

Lesson 1 • Permit and Plan Review Basics

Covers the permit application workflow and basic plan review criteria. Connects documentation review to field inspection readiness.

Lesson 2 • Inspection Documentation and Records

Explains how to complete inspection reports, correction notices, and certificates. Accurate records protect inspectors legally and support code compliance tracking.

Lesson 3 • Role and Authority of the Inspector

Defines the legal basis, scope, and limits of inspector authority. Establishes why understanding jurisdiction and enforcement powers is essential before any field work.

Lesson 1 • Power, Energy, and Heat

Explains real, reactive, and apparent power and their inspection implications. Connects heat generation to conductor ampacity and equipment ratings.

Lesson 2 • Earthing and Bonding Theory

Explains why earthing and bonding are required and how they function electrically. Builds the theoretical foundation for the earthing inspection chapter.

Lesson 3 • AC Fundamentals and Waveforms

Introduces alternating current, frequency, and phase relationships. Prepares inspectors to evaluate single-phase and three-phase system installations.

Lesson 4 • Magnetism and Transformer Basics

Covers electromagnetic induction and transformer operation at an inspector-relevant level. Enables evaluation of transformer installations and secondary voltage verification.

Lesson 1 • Boxes, Enclosures, and Fittings

Explains box fill calculations, enclosure types, and fitting requirements. Proper box selection prevents overheating and ensures safe conductor terminations.

Lesson 2 • Raceway Systems

Covers conduit types, fill calculations, and installation standards. Raceway compliance is critical in commercial and industrial inspections.

Lesson 3 • Cable Assemblies and Their Applications

Identifies common cable types, their permitted uses, and installation restrictions. Inspectors must distinguish approved from prohibited applications by occupancy and location.

Lesson 4 • Wiring in Special Locations

Addresses wiring method restrictions in wet, damp, corrosive, and high-temperature environments. Inspectors apply location-specific rules to approve or reject installations.

Lesson 1 • Residential Load Calculations

Walks through the standard and optional methods for calculating dwelling unit loads. Inspectors use these calculations to verify service size adequacy.

Lesson 2 • Feeder and Service Sizing

Applies demand factors and load calculations to size feeders and service conductors. Accurate sizing ensures safety without over-engineering.

Lesson 3 • Branch Circuit Protection Rules

Covers maximum overcurrent device sizes for branch circuits by conductor and load type. Inspectors verify that device ratings match conductor ampacity and load requirements.

Lesson 4 • Commercial and Industrial Load Calculations

Extends load calculation methods to non-dwelling occupancies with diverse load types. Prepares inspectors for complex panel schedule reviews.

Lesson 1 • AFCI Protection Requirements

Covers arc-fault circuit interrupter requirements by room type and circuit configuration. Inspectors confirm correct device type and installation to prevent electrical fires.

Lesson 2 • Service and System Bonding

Addresses main bonding jumpers, system bonding jumpers, and supply-side bonding. Correct bonding ensures fault current returns to the source to trip overcurrent devices.

Lesson 3 • Earthing Electrode Systems

Covers required electrodes, connections, and conductor sizing for earthing electrode systems. Proper electrode installation is the first line of defence against voltage surges.

Lesson 4 • GFCI Protection Requirements

Maps all locations requiring earth-fault circuit interrupter protection by occupancy and environment. Inspectors verify device placement, testing, and labelling compliance.

Lesson 1 • Switchgear and Switchboard Inspection

Extends panel inspection skills to larger switchgear and switchboard assemblies. Inspectors evaluate bus ratings, labelling, and arc-flash hazard markings.

Lesson 2 • Working Space and Dedicated Space

Applies code-required clearances around electrical equipment for safe operation and maintenance. Inspectors reject installations that block required working or dedicated space.

Lesson 3 • Service Entrance Requirements

Covers service drop and lateral clearances, point of attachment, and service head requirements. Correct service entrance installation prevents contact hazards and weather damage.

Lesson 4 • Panelboard Inspection Criteria

Addresses panelboard ratings, circuit directory, and interior wiring requirements. A thorough panel inspection catches the majority of residential and commercial violations.

Lesson 1 • Assembly and Educational Occupancies

Covers emergency lighting, exit signs, and egress path wiring for high-occupancy buildings. Inspectors confirm life-safety systems are independent and properly powered.

Lesson 2 • Agricultural and Marina Installations

Applies unique earthing, equipotential, and wiring rules for farms and marina facilities. These environments present elevated shock and corrosion risks requiring special inspection focus.

Lesson 3 • Healthcare Facility Electrical Requirements

Addresses essential electrical systems, patient care areas, and isolated power requirements. Healthcare inspections require understanding of life-safety system redundancy.

Lesson 4 • Hazardous Location Classification

Introduces the class, division, and zone classification systems for flammable and combustible environments. Correct classification drives every subsequent equipment and wiring decision.

Lesson 1 • Exam Strategy and Question Analysis

Teaches how to decode exam question stems, eliminate distractors, and manage time. Strategic test-taking raises scores independent of additional content knowledge.

Lesson 2 • Timed Practice Exams and Review

Administers full-length timed practice exams followed by detailed answer review. Repeated testing under exam conditions builds speed, accuracy, and confidence.

Lesson 3 • Mock Inspection Scenarios

Presents realistic residential, commercial, and industrial inspection scenarios for practice. Scenario-based learning bridges code knowledge and field judgement.

Lesson 4 • Code Interpretation and Application

Develops skills for resolving ambiguous code language and applying intent over literal reading. Inspectors who interpret code correctly make defensible, consistent decisions.
