In your case I would insist on an insulation certificate .
OK spell check got it wrong. But it is serous.
631.1 Upon completion of the verification of a new installation or changes to an existing installation, an Electrical Installation Certificate, based on the model given in Appendix 6, shall be provided. Such documentation shall include details of the extent of the installation covered by the Certificate, together with a record of the inspection and the results of testing.
Without that bit of paper if anything goes wrong "woody2" could be looking at a custodial sentence with the paper he may only get fined.
My foreman and I do feel sorry for him told us we had to do the job when we tried to back-heal it. And asked us to do work which was not electrical. Had everything gone well he would have got pat on the back. But I was injured and then it really got nasty for him. Don't know whole story his solicitors told him he must not contact me. But he lost his job and I am sure it was not easy to find any future employment and he did not get compensation. The Spark working with me blames himself he was very close to becoming an alcoholic because of this. He removed to lock and did not replace it and turned the machine on while I was working on it.
And like "woody2" it was not really our job but we were through circumstances drawn into it. Had it been our job we would have known the method that should have been followed. (Method statement) we would have also have carried out a risk assessment. Likely there would have been no accident. Also like most accidents there were other faults. Isolator in wrong place. Wrong colour switches used for personnel safety,
314.1 Every installation shall be divided into circuits, as necessary, to:
(i) avoid hazards and minimize inconvenience in the event of a fault
Was the main fault.
But no one could have foreseen the result.
I like many others have worked on jobs were you just do as your told. Connect wire A to box B following plan and you have no idea if the installation complies or not you are just another cog. But as soon as someone says I want you to complete an "Electrical Installation Certificate" this all changes and you may it your business to ensure it complies. I have many times been employed and sent to a site to work where my employer has no idea what I am doing he is just supplying labour. So you could get a load of electricians arrive on site who just do as they are told and think the foreman is an electrician or electrical engineer and will do as they are told within reason. They would expect the person in charge to sign any paperwork and would not consider the job as a whole.
So only by ensuring there is an "Electrical Installation Certificate" can you be sure some one other than yourself has taken responsibility for the work and that they have the skill and knowledge required. Both my son and I have worked doing nothing else but check other peoples work and there have been times when an admin error has resulted in work not being checked and we have had to return to a powered up site which has been done by electricians without a 2391 and I have been dismayed at some of the work I have found. But normally they have done exactly what they have been told to do. Not bad workmanship just done without considering the installation as a whole. Often due to not having a test set so they were unaware what they had done was wrong. Had they been issued with test set even without a 2391 likely they would not have made the mistake.
So again someone must take responsibility and if I was asked to sign an "Electrical Installation Certificate" without having access to a test set I would refuse and this would then highlight that testing was not being done.
Sorry to go on so. But it is serous
