Electrical Test and Tag Course

Lesson 1 • Regulatory and Standards Framework

Introduces the hierarchy of electrical safety regulations, standards, and codes of practice without referencing jurisdiction-specific identifiers. Students understand which documents govern testing frequency and methods.

Lesson 2 • Basic Electrical Principles

Covers voltage, current, resistance, and power relationships essential for interpreting test results. Provides the conceptual base for all subsequent measurement and inspection tasks.

Lesson 3 • Workplace Electrical Risk Overview

Identifies common sources of electrical risk in commercial and industrial environments. Connects hazard recognition to the duty-of-care obligations that drive test-and-tag programs.

Lesson 1 • Appliance Classification Systems

Explains Class I, Class II, and Class III appliance categories and their insulation strategies. Classification directly determines which electrical tests are required and at what limits.

Lesson 2 • Fixed vs. Portable Equipment

Distinguishes between fixed-wired equipment and portable appliances subject to test-and-tag programs. Clarifies which assets fall within scope and which require different compliance pathways.

Lesson 3 • High-Risk Appliance Categories

Identifies appliance types that carry elevated failure risk due to environment, usage intensity, or construction. Prepares students to apply shorter retest intervals and heightened inspection scrutiny.

Lesson 1 • Inspecting Plugs and Sockets

Teaches a structured approach to examining plug bodies, pins, and socket outlets for damage. Students practice identifying cracks, burn marks, bent pins, and loose connections.

Lesson 2 • Cord and Cable Inspection

Covers inspection of the full cord length from plug to appliance entry point. Students learn to detect cuts, abrasions, kinking, and improper strain relief.

Lesson 3 • Purpose and Limits of Visual Inspection

Explains why visual inspection is the first and most frequently performed safety check. Establishes what visual methods can and cannot detect compared to electrical testing.

Lesson 4 • Appliance Body and Controls Inspection

Guides inspection of the appliance housing, switches, guards, and ventilation openings. Connects physical damage findings to potential internal faults that electrical tests will confirm.

Lesson 1 • Tester Setup and Calibration Checks

Covers pre-use checks, self-test routines, and verification against known reference standards. Students understand calibration intervals and how to identify an out-of-tolerance instrument.

Lesson 2 • Tester Maintenance and Storage

Establishes routines for cleaning, storing, and transporting testing equipment safely. Proper maintenance preserves accuracy and extends instrument service life.

Lesson 3 • Reading and Interpreting Tester Outputs

Explains how to read numerical results, pass/fail indicators, and error codes on PAT testers. Students develop confidence in distinguishing valid results from instrument or connection faults.

Lesson 4 • Types of Portable Appliance Testers

Surveys manual, semi-automatic, and fully automatic PAT tester designs and their feature sets. Students match tester capability to the appliance classes and test types they will perform.

Lesson 1 • Functional Operation Check

Establishes the powered functional test as the final confirmation that an appliance operates safely under load. Students learn what to observe and how to document functional test outcomes.

Lesson 2 • Earth Continuity Testing

Explains how earth continuity tests verify the integrity of the protective earth conductor in Class I appliances. Students learn acceptable resistance limits and what high resistance indicates about appliance safety.

Lesson 3 • Leakage Current Testing

Introduces touch current and protective conductor current measurements as alternatives to insulation resistance. Students understand when leakage tests are preferred and how to apply pass/fail thresholds.

Lesson 4 • Polarity and Wiring Verification

Teaches polarity checks that confirm active, neutral, and earth conductors are correctly connected. Wiring errors that pass insulation tests but create shock risk are identified here.

Lesson 1 • Testing Class I Appliances

Walks through the full test sequence for earthed appliances, including earth continuity, insulation resistance, and functional checks. Students apply correct limits and sequence steps without omission.

Lesson 2 • Testing RCDs and Safety Switches

Introduces residual current device testing as a complementary safety check within test-and-tag programs. Students perform trip-time and trip-current tests and interpret results against standard limits.

Lesson 3 • Testing Class II Appliances

Adapts the test sequence for double-insulated appliances where no earth conductor is present. Students understand why earth continuity is skipped and how insulation limits differ.

Lesson 4 • Handling Unusual and Non-Standard Appliances

Prepares students to make sound testing decisions when appliances have non-standard connectors, multiple supply voltages, or built-in RCDs. Judgment-based approaches replace rigid sequence application.

Lesson 1 • Retest Interval Determination

Teaches how to assign correct retest intervals based on appliance class, environment, and usage frequency. Students apply risk-based interval tables without referencing jurisdiction-specific codes.

Lesson 2 • Tag Types and Their Correct Use

Distinguishes pass tags, fail tags, and out-of-service tags by color, content, and placement requirements. Correct tag selection and attachment are the visible output of every test-and-tag inspection.

Lesson 3 • Audit Readiness and Record Retrieval

Prepares students to present test records during workplace safety audits and regulatory inspections. Organized, retrievable records demonstrate due diligence and reduce liability exposure.

Lesson 4 • Paper and Digital Record Systems

Compares manual logbooks with digital asset management and barcode/RFID systems for test records. Students understand minimum data fields, retention periods, and retrieval requirements.

Lesson 1 • Immediate Response to a Failed Test

Defines the actions required the moment an appliance fails any visual or electrical test. Prompt isolation prevents continued use and protects workers from ongoing hazard exposure.

Lesson 2 • Reporting and Escalation Procedures

Establishes when and how to escalate failures to supervisors, safety officers, or licensed electricians. Clear escalation paths ensure systemic faults receive appropriate professional attention.

Lesson 3 • Retesting After Repair

Covers the full retest sequence required before returning a repaired appliance to service. Students understand that repair does not automatically restore compliance without verified testing.

Lesson 4 • Repair, Replacement, and Disposal Decisions

Establishes criteria for deciding whether a failed appliance should be repaired, replaced, or disposed of. Cost, age, failure severity, and repair feasibility all inform the decision.
