RCD protection in an IT run office

I don't think that we were giving you a personal attack, it is a reflection on personal competence. You say you are fully qualified, perhaps you would like to list the qualifications, as I did above to be an Inspector working on EICRs. So I assume that you have the 18th exam, and your mark was 90% or more (very few achieve that) but inspectors should ideally get 100%. I assume you have a pass of 2391 before the last lot of changes with a pass rate of less than 30%, I have, first time and a prize. You say you have experience, then why the range of silly mistakes above which very few reading here even make in singles? Why do you not have a copy of BS7671 18th edition Amdt 1, or if you do why do you fail to understand the contents? There are a myriad of questions, particularly as you obviously don't know what an IT system is, when this is in section 710, and the section which mentions IT (ICT) is 331 and a few others. An inspector cannot work without a very thorough and accurate knowledge of the regulations, if not how can he inspect anything? It is simply not possible. If you have only an OSG, the job cannot be done at all, the OSG is a very simplified guide for the less experienced on how to do simple installations that are compliant, but not in any way optimum, just by following a few simple rules. The inspector must recognise all possible compliant installations and designs, and be able to check all the features even if they have never been seen by him before. A very difficult capability that requires a lot of knowledge and experience.


You should take this set of replies as something of a warning, not necessarily as a criticism. Inspection is probably harder than good design, particularly of larger installations. The risks of getting it wrong are much greater, everything from prosecution by the HSE under the EAWR, to claims of fraud or damages from clients, or loss of your Professional Indemnity Insurance which I presume you have. These may be rare but do happen, and getting PII after a significant claim may put you out of work for good. Please take notice, we are trying to help you. This is not the place to learn how to inspect but is the place where serious basic knowledge may be gained. If you work for a company that uses the QS system, you will be the first out of the door if your inspection has any mistakes contained in it, even if the QS signs. I have dealt with two cases of this, this week, both are untrue reflections of the installation, in order to gain reparation work and are basically fraudulent. I assure you that repercussions will follow for several people.


If you need help, JohnP is one of the most respected inspectors in the country. I would not advise you to be opposite him in court, but he often advises people here on some of the more difficult questions which are asked. Neither of us was trying to be rude in the usual forum sense, just honest.


Take care
