PAT

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

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

Therefore, all electrical systems must be maintained in a safe condition and an important aspect of such maintenance is periodic inspection and testing of portable electrical appliances and fixed hardware installations.
