The electrical wires are dangerous when they have the potential (voltage) and (amperage) capability to enough to harm you. 

A lot can happen with and by electricity. It is that thing that lights up your life and may also land you in most undesirable disasters.

There is a simple but very crucial solution to these problems.

PAT TESTING. You might have heard about it.

Above alluded are just the trivial effects of not having PAT tests in your houses or commercial settings.


The problems may only multiply and intensify gradually if not scrutinized and corrected at the most appropriate time.

Moreover, abiding by law is another most important reason why it is indispensable to get your appliances PAT tested.

What Does PAT Testing Stand for And What It Is About?

PAT can be expanded as Portable Appliance Testing.

As by the full form, we discern that it is a process-based service which is availed by residents in order to ensure safety measures with electronic appliances.

Electric hazards can be highly onerous to prevent if a regular check over the things is not done.

A regular check-in PAT testing makes you sure of safety in case you are using an appliance regularly or in long intervals too.

PAT for Domestic as Well As Commercial Use:

PAT testing is a service made use of both in professional as well as domestic terms.

People make PAT tests conducted at their homes for strengthening their security from the disasters that inappropriate electrical circumstances may bring to them.

In their business offices, PAT lets organizations depend on the electrical machinery more steadily when some appliances are left to use for employees.

This also makes employees feel safer at their workplace. Moreover, it gives organizations a mild and safety regulated playground for the free working of their valuable resources.

This way it is beneficial for both the sort of settings.


What Does PAT Testing Involve?

•    At first, it involves a process of a thorough visual examination of the worn-torn wires, damaged or exposed parts of appliances and the plugs and sockets that don’t appear to be in the right condition.
•    The all above sets a base for the next piece of action that is to be conducted in order to repair and up-do the fault carrying or hazard-prone areas.
•    Quality tests are then to be conducted over several parts to see if the things other than those visible are in the right place. Those tests may be earth continuity tests, insulation resistance test and many more that your PAT tester must be knowing about.
