PAT Testing For Commercial Dishwashers

What is PAT Testing?

“Portable Appliance Testing” more commonly known as a PAT test is an inspection in the UK (as well as Northern Ireland, New Zealand and Australia) in which electrical appliances are checked for safety. The Testing encompasses a visual inspection of the equipment including any flexible wires or cables to determine their condition. Also, when necessary verification of Grounding (earth-wire) continuity and a test of the status of the insulation between parts carrying current and any metal that is exposed that could potentially be touched.

Is it a legal requirement?

The Appliances British Law requires that all electrical systems including electrical appliances are maintained to prevent danger. Health and Safety regulations require that electrical devices are safe and are properly managed to ensure the prevention of harm to employees. The HSE (Health and safety executive) and the local authority are the ones who enforce this legislation.

Not every electrical appliance will need to be PAT tested. In some cases, a simple user check and visual inspection are enough, e.g. checking for loose cables or signs of fire damage and, if possible, checking inside the plug for internal damage, bare wires and the correct fuse.
