Covers inspection of the full cord length from plug to appliance entry point. Learners 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 5 • Documenting Visual Inspection Findings
Introduces standardised methods for recording pass, fail, and advisory findings from visual checks. Accurate documentation supports the tagging decision and audit trail.
Chapter 4HideHide detailsSee detailsTest and Tag Equipment Operation
Test and Tag Equipment Operation
Lesson 1 • Tester Setup and Calibration Checks
Covers pre-use checks, self-test routines, and verification against known reference standards. Learners 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. Learners 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. Learners match tester capability to the appliance classes and test types they will perform.
Lesson 5 • Connecting Appliances to the Tester
Teaches correct plug insertion, probe placement, and accessory use for different appliance types. Proper connection prevents false results and protects both the tester and the appliance.
Chapter 5HideHide detailsSee detailsCore Electrical Tests Explained
Core Electrical Tests Explained
Lesson 1 • Functional Operation Check
Establishes the powered functional test as the final confirmation that an appliance operates safely under load. Learners 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. Learners learn acceptable resistance limits and what high resistance indicates about appliance safety.
