Periodic inspection and testing is a demanding, difficult and responsible part of the job. In principle the job is simple, inspect the installation to ensure it is safe for continued use then perform some basic tests, however you are often looking at older installations built to previous versions of BS7671, many are suffering deterioration or damage and of course various additions and modifications done sometimes by amateurs and diyers. Your knowledge of the current regs needs to be good and a knowledge of earlier regs is helpful. Then there is the coding for deviations from the regs and your final assessment after sometimes arduous testing, whether it is actually safe or not.
These are the things we will discuss in class as well as how to pass the exam and some advanced techniques.
The small group size enables us to talk about real life situations (both yours and mine) that we have come across that will illustrate the technical discussion.
And for the record, the written exam is not nearly as bad as you think. I always hold a short discussion and revision just before the exam so you have the best chance of passing. Most people pass first time but some take longer and that is ok. Persistance is all!
And remember we include a days practice in the workshop to brush up your skills before the practical exam. .
