A few years back - about 12 months before Part P actually came in so say the mid to end of 2004, a colleague of mine had done the C & G 2380 (Wiring Regs course) but unlike me had aborted his decision to do the C & G 2391 (Inspect and Test) course because at only a very few years before retirement he got a job with an NICEIC firm so he decided he wouldn`t be needing the I & T certificate. The firm folded and Part P had come in so he came working with me for a couple of years and his jobs became my jobs and we worked together on both our jobs and I was the qualifying supervisor.
Anyway, I showed him the correct procedure for I & T whilst we were working together and he was gobsmacked. Apparently the other firm tested one new build and certified 20 identical installations based solely on the test results of that particular one only. (actually many of the tests were not done properly either buts another issue). So you could have as many as 19 defective installations bearing so called test results of one other. But this actually was greatly demonstrated as a flawed test procedure by that one installation we shared - No ring continuity on one ring final. We had a quick visual check of the sockets we had wired in to see if any were missing. "Phill, have you checked all of yours?", "Yes" , "All of them?" "yes", "Did you check the one in the loft?", "No but i will get ladders out and check it now but I am certain I did connect it, whoops, oh no i didn`t, I will do it now!" . Anyway retested and all OK.
I asked him what would happen if he or others did likewise at the other firm, potentially 19 bad uns out of the 20 he said. LOL.
I have stood in some houses looking at periodics and wondering if I am in the correct house even though the addresses do match up what I see in front of me does not. LOL
