What is the purpose of PAT testing. There are many differing opinions on the subject. However we will look at the subject from an angle which is so often overlooked, that is the regular maintenance of your appliances.
It is a common misconception that PAT testing has to be carried out every year as a legal requirement. However the law requires electrical equipment to be maintained where practical to prevent accident or injury.
When and how often should a PAT test be performed.
It is a decision that each and every business will have to make for themselves, every business sector is different. The frequency of inspection and testing is influenced by the appliance itself, where it is used and what it is being used for. For instance would a printer lead under an office desk require the same level of inspection and testing as an extension lead used on a building site?
As may be necessary to prevent danger, all systems shall be maintained so as to prevent, so far as is reasonably practicable, such danger.
