What is “PAT” – What does “PAT” stand for?

A selection of portable electrical appliances

‘PAT’ stands for ‘Portable Appliance Testing

PAT is a process of inspecting and testing portable electrical appliances;  a portable appliance is any electrical appliance that is powered from a plug and socket outlet. 

This makes the word portable misleading, as it has nothing to do with whether you can move the appliance. In fact a portable appliance can be fixed to the wall (providing it has a plug – not those directly wired into the mains), stationery equipment such as fridges and washing machines, IT equipment like computers and printers, movable equipment like televisions and microwave ovens, portable equipment such as toasters and kettles, detachable leads, extension cables and hand-held appliances.
