Class 1 Appliances
With Class 1 appliances, the user is protected by a combination of basic insulation and the provision of an earth connection, thus providing two levels of protection. When PAT Testing Class 1 appliances, Earth Continuity and Insulation Resistance tests are carried out. So in summary:
- If it is made of metal it should be a Class 1 appliance
- If it has a three core cable it should be a Class 1 appliance
- If the plug has a metal Earth pin it should be a Class 1 appliance
Typically fridges, microwaves, toasters are all Class 1.
