Michael Drury has worked in the electrical industry for over 50 years, and is currently working as a freelance electrical installation lecturer and as an on-site constructor, designer and inspector. Michael has worked in FE for 25 years and has also been employed as a contractor in the United Arab Emirates and Saudi Arabia.
The process of inspecting and testing electrical installations has evolved over a number of decades, as electrical equipment has become more prolific and sophisticated.
Consequently, the demands on the practising electricians are ever increasing both at the skills level and those imposed by accumulative regulative liabilities.
In order to cope with these increasing demands there is a constant urgency to develop and maintain appropriate and necessary skills to meet the pressures imposed on them by Statutory and Non-Statutory Regulations;
which have sensibly been introduced and frequently up-dated, in order to reduce or possibly eliminate the number of fatalities, serious injuries in the work place and the domestic environment, also to prevent damage to property.
Safety has always been, and must be, at the forefront of all practising electricians’ work ethos, which oddly can be a problem when they sit the City & Guilds 2391 theory exams;
simply because they have a natural reaction to solve or rectify an electrical fault, which may have been exposed during an inspecting and testing routine.
Consequently, if a candidate (inspector/electrician) is presented with a question on a possible fault, defect or omission, this natural reaction may kick in.
Unfortunately this type of response is not expected from the candidate during the theory exam. The answer given will ultimately depend on the mode of the inspection paper, whether it’s Initial Verification,
Periodic Inspection, or a combination of both, the response will be entirely different. Accordingly candidates must always bear in mind their position as an inspector when sitting the theory exam(s);
where they are expected to carry out the inspection and testing of an installation regardless of the type of inspection and give an account on its condition.
Subsequently, it is paramount for the candidate (inspector) to understand the testing and inspection procedures, with all the associated certification and schedules, as laid down in the current version of BS 7671 Wiring Regulations and the IET Guidance Note 3 Inspection & Testing.
