As is often the case, many people are unsure which items require PAT.  In simple terms, an item that has a plug, is used in the workplace and powered by a mains supply and can be easily moved.  This is a Portable Appliance that requires Testing or PAT on a regular basis as recommended by the IEC code of practice for in-service inspection and testing of electrical equipment.

There are basically 2 electrical types. Class 1 and Class 2.

Class 1 items are earthed.  Class 2 are not earthed.
