PAT - Portable Appliance Testing

The Electricity at Work Regulations 1989 require that any electrical equipment that has the potential to cause injury is maintained in a safe condition.

Portable appliance testing (PAT) is the term used to describe the examination of electrical appliances and equipment to ensure they are safe to use. 

Formal visual inspection and testing by a competent person may be required at appropriate intervals, depending upon the type of equipment and the environment in which it is used.

Most electrical safety issues can be found by visual examination but some types of defects can only be found by testing.
