PAT Testing

PAT Testing

All businesses must carry out Portable Appliance Testing (PAT) which involves checking electrical appliances and equipment on a regular basis, to ensure that it is safe to use and meets relevant standards to minimise the occurrence of accidents and injuries within the workplace.

Exposed wirings and loose connections can cause severe harm, and in rare cases, lead to death. Unchecked electrical issues are also a fire risk, which endangers not only the employees but also the entire business.

All users of electrical equipment should have basic training and awareness as part of any electrical maintenance system. However, a more formal inspection and testing regime is required to be carried out by a competent electrician at regular intervals.

At ADE Electrical Solutions Bromsgrove our engineers have a vast amount of knowledge and expertise in this area. We have the correct equipment and ability to carry out the tests and can interpret the results correctly.

Portable Appliance Testing

The frequency of testing is dependent upon the type of equipment and the environment in which it is used. Class indicates the frequency according to their risk level.

  • Class 1 appliances require a full PAT inspection because they have low insulation and rely on the earth for protection. Examples include photocopiers, industrial, machinery, freezers, toasters, irons, laptop cables, desktop computers, phone chargers and microwaves.
  • Class 2 appliances include lamps. televisions and lawnmowers. These are considered generally safer because they are double-insulated.
  • Class 3 appliances are low voltage and include laptops, torches and cameras. These appliances are considered the safest.

Most defects can be identified through visual inspection, but certain defects can only be highlighted by testing. Electrical inspection utilises specialised PAT devices to detect some types of defects. The procedure includes checking earth resistance, earth continuity, and insulation resistance tests, as well as polarity and safety-switch checks. It is important to note that visual inspection is an imperative part of the process as there are certain cases which cannot be detected by testing alone. Visual testing seeks for indications of damage such as cracks, scorch marks and signs of wear.

Records of testing are useful documents as part of effective management as they enable appliances to be easily monitored and reviewed. In addition, many insurance companies stimulate regular PAT testing is completed as standard.

We understand that sometimes testing can appear to be disruptive to your business, therefore we offer ‘out of hours’ testing services where required and for business-critical systems that cannot be switched off, visual inspection is offered.
