What is Portable Appliance Testing?

Portable appliance testing (PAT) is the term used to describe the examination of electrical appliances and equipment to ensure they are safe to use. You can find most electrical safety defects by a visual examination. Some types of defect can only be found by testing.

A relatively brief user check can be a very useful part of any electrical maintenance regime. However, more formal visual inspection and testing by a competent person may also be required at appropriate intervals. Choose a competent person to carry out your formal testing. Ensure that the person is suitably qualified and experienced at using the test equipment. Do not leave your Portable Appliance Testing to a novice.
