Any appliance that has a plug that will be connected to a wall socket or generator needs PAT testing. All these various electrical appliances need to be PAT tested to ensure that they are safe to use. Each appliance goes through a visual inspection first followed by an earth continuity test, lead polarity and insulation resistance checks.
All electrical appliances are categorised into different classes which determines which appliances need PAT testing. Electrical appliances are categorised into class 1, 2 or 3.
Class 1 appliances are the most dangerous and require a full PAT test. Examples of Class 1 appliances are:
– Floor standing printers
– Desktop computers
– Industrial machinery
– Fridges
– Washing machines
– Kettles
– Irons
– Mobile phone chargers
– Tumble dryers
Class 2 appliances have extra insulation so they only require a PAT insulation test. Examples of Class 2 appliances are:
– Desktop printers
– Lamps
– Televisions
– Food mixers
– Hairdryers
– Hair straighteners
Class 3 electrical appliances are the least dangerous and do not require a PAT test at all. Their charging cables may need to be PAT tested. Examples of Class 3 appliances are:
– Laptops
– Mobile phone chargers
– Cameras
