As we are obviously using electricity to test our electrical equipment, it makes sense that we need to understand what electricity is and how it works.
This is a brief section, as anyone carrying out 'PAT Testing' should already have a good understanding.
Electrical equipment is often very safe, until it is put in the hands of the user of the equipment. Potentially, the user of the equipment has a greater responsibility, especially if they are using it on a regular basis.
Not every piece of electrical equipment is the same. Obviously they have different jobs to do, but what about the safety features built into them? We need to understand what safety features should be present prior to deciding what tests we need to carry out.
The test device acts like an x-ray machine... it gets to the parts of the electrical equipment which we can't usually get to, without taking the item to pieces. The tests we carry out vary from item to item and must be carried out correctly and in the right order.
Your test device says the electrical equipment has 'passed', but does the test device know everything about the item being tested? Unlikely, so it is up to you to check the results against industry standards.
Hopefully the previous topics and your prior knowledge of 'PAT Testing' will have prepared you for your final test.
There are no trick questions, but they are not that easy either. Take your time and remember to READ THE QUESTION.
