Portable Appliance Testing (PAT)

Portable Appliance Testing (PAT) is the process of inspecting and testing electrical appliances to ensure they are safe for use. It involves visual checks and electrical tests to identify any potential faults or hazards.

The frequency of PAT testing depends on the type of equipment and the environment in which it is used. Typically, appliances in commercial environments should be tested annually, while those in domestic settings may require less frequent testing.

PAT testing should be carried out by competent individuals with the necessary knowledge and training to conduct inspections and tests safely and accurately. This often includes qualified electricians or PAT testing specialists.

PAT testing involves a series of visual inspections and electrical tests to assess the safety and functionality of portable appliances. This may include checks for damaged cables, loose connections, and insulation resistance tests.

While there is no specific legal requirement for PAT testing, regulations such as the Electricity at Work Regulations 1989 require employers to ensure the safety of electrical equipment. PAT testing is a commonly accepted method for meeting these obligations.

The duration of PAT testing depends on factors such as the number of appliances being tested and their complexity. Generally, a small number of appliances can be tested within a few hours, while larger inventories may require more time.
