All electrical appliances using mains voltage have to provide at least 2 levels of protection to the user. This is to ensure that if one of the protection layers were to fail, there is the back-up of the second layer still in place. This makes electrical equipment very safe to use. Appliances can be Class 1 or Class 2. When PAT testing, it is important to first identify the Class of the appliance as Class 1 appliances are tested differently from Class 2 appliances.

Checking fuses in Plugs
This subject seems to always causes much confusion during our PAT Training courses - so thought about covering this in our first post.
During the course our advise is:
In a working appliance, if you find a 3 Amp or 5 Amp fuse then there is no need to change this. Just leave this in place.
If you find a 13A fuse, then check the power rating. This is usually found marked in Watts on the rating plate.
