Test and tagging is a generic name given to the process of visually inspecting and electrically testing in-service electrical equipment for personal safety. Colloquially, it is also referred to as; tagging, test tag, test and tag, electrical tagging, appliance testing, portable appliance test or lead tagging.
The aim of test and tagging is to determine if the appliance is electrically safe for personal use. The appliance undergoes a visual inspection for defects such as damage or missing components and a number of electrical tests to measure earth continuity, insulation resistance and polarity.
In Australia and New Zealand, this is done using the Standard; AS/NZS 3760:2010 “In-service inspection and testing of electrical equipment” as a reference document.
Electrical safety and regular yearly inspections of your electrical tools, appliances, power leads, extension leads and all other workplace and home electrical equipment are not to be taken lightly.
