What is PAT Testing?
Portable Appliance Testing (PAT) is the process of inspecting and testing electrical appliances to ensure that they are safe to use. The purpose of PAT is to prevent electrical accidents in the workplace, home or any other setting where electrical appliances are used. During a PAT, a trained technician will inspect the electrical appliance for any damage or defects that could cause harm.
PAT is especially important in settings where appliances are used frequently or by multiple people, such as offices, schools, and public spaces. By regularly testing and inspecting electrical appliances, potential hazards can be identified and corrected before they lead to accidents, injuries, or even fatalities.
Class 1 appliances protect the user through a combination of basic insulation and earth grounding, providing two layers of protection.
Class 2 appliances protect the user by at least two layers of insulation, known as Double Insulated. These devices do not require an earth connection.
