WHAT IS A PAT TEST?

---

User checks are mostly common sense. You do not need to be electrically trained to do them. If you’re concerned about something; don’t plug it in.

But what is a user check? It is a simple check of the appliance to make sure it looks safe to use.

For this you will need to be a competent person. This is similar to user checks, However a more detailed look at the appliance is required. An assessment is made as to the suitability of the equipment for the intended task.  Where possible, the plug needs to be opened to ensure it is wired correctly The terminals and cable grip are tight. The fuse is correct. The wires do not have excess wire exposed. And there are no signs of damage or overheating within the plug.
 

 A combined inspection and Test is, as the name suggests, a combination of a Formal Visual Inspection with The electrical tests carried out with a PAT Testing machine.

The level of competence required is much greater than for just a Formal Visual Inspection.  A greater understanding of the principles of Earthing and Insulation are required, As well as a clear grasp of the risks posed by faulty electrical equipment. The industry recognised standard of training is the City and Guilds 2377 qualification. 

  The Class of the appliance is dictated by the danger they pose to the user. There are three Classes; Class 1, Class 2 and Class 3. Class 1 is considered the most dangerous, and Class 3 the least. They are categorised as follows: 

• Class 1 These appliances hold limited insulation and require an earth to protect both appliance and user. Examples include Freezers, Irons, Photocopiers and Microwaves. 

• Class 2 These appliances hold greater insulation and therefore do not require an earth – making them safer. Examples include Lawn mowers, TVs, Lamps and Drills.

• Class 3 These appliances have a low voltage and pose the lowest risk to the user however, any charging leads that accompany the device may need testing. Examples include Laptops, Phone mobile chargers and Cameras.
