Frequently Asked Questions
What does PAT testing involve?
PAT testing involves a visual inspection of the appliance, plug, and cable, followed by electrical tests using specialist equipment. Tests check for earth continuity, insulation resistance, and protective conductor current.
What is the difference between Class I and Class II equipment?
Class I equipment relies on earthing for safety (e.g., metal-cased appliances). Class II equipment has double insulation and does not require earthing (e.g., most modern power tools and appliances with plastic casings).
What happens if an item fails PAT testing?
Failed items are labelled accordingly and removed from use. Our engineer will advise on whether the item can be repaired. Minor repairs such as plug top changes are carried out on the spot at no extra charge.
