Not being one who could ever resist a rant………………and part P was mentioned……………….
I was apprentice trained as an Electrical Engineer in the early seventies. I went to tech colledge for three years as well. I came out of my training with a C&G National diploma in Electrical Engineering, Between then and the introduction of part P I have done everthing from domestic rewiring (Considered by all in the trade as rock bottom!) to heavy duty maintenance and installation in flour mills, gravel and sand plants, print works, food production plants etc etc.
Part.P was introduced by the "office of the deputy prime minister" a post specially created for Mr John Prescot. According to the website of the now defunct ODPM
"This legislation is introduced to stem the rising tide of electrical accidents in the home"
According to this legislation, if I want to carry on doing "certain specified work under part P", work I have been doing for thirty years or so, I must pay a large sum of money to have one of my jobs inspected, and then an annual fee to one of the "schemes of registration" to continue to work. The strange thing about this is that there actually was no "rising tide of electrical accidents in the home" In fact the "tide" has been falling steadily since about 1962. How do I know? I was involved in some research for a group which was originally consulting with the govenment on Part P, and whose services were dispensed with when they came to the conclusion that part P was a very bad idea and should not be introduced. The research I did found out that there were two bodies who kept safety data for electrical accidents in the home, RoSPA, and the now long gone Department of trade and Industry. When the DTI ceased to be they passed their accident database on to RoSPA, and Rospa passed copies of both databases on to me, after telling me that the data was far from complete, as it was based on information supplied by 12 A&E departments at major hospitals up and down the country. Nevertheless, the data showed quite clearly that the "rising tide" statement was totally false..
Fast Forward to today, and the Part P Training industry is really going strong, and now you can go from the dole queue, with no previous experience in any engineering field, to being a part P approved person (You can rewire houses) in just 5 weeks! Of course it is expensive, anything up to 5 grand!! Given the age I am, and my almost zero interest in domestic rewiring, I will not be applying
Anyone who does will be in for a shock too because after they have finished their training, the chances of them getting a job in the industry are negligible, because the vast majority of domestic rewiring has now been done, it boomed from the sixties till the early nineties, then the market flattened out, and domestic rewires are a mere trickle of the workload. Of course all the work done during this time is not part P compliant and never will be!
Despite all that the new systems must be safer, or there would bo no reason to introduce them would there?
Well actually, they are not safer at all. Because the old IEE regulations (which were arrived at by senior electrical engineers, and actually contained a definition of a "competent person" who was deemed well qualified enough to use and apply the regulations (5 year apprenticeship, plus a recognised technical qualification and at least three years experience after the apprenticeship!) have been supeseeded by the IET regulations, the compilers of which are mainly manufacturers, not electrical Engineers (if you have the big red or green book, its all in there)
The IEE regs used to state, "any mechanical device fitted in a circuit as a means of providing protection against fault currents or overload shall itself be fail safe"
No such regulation exists in the IET regulations, and it couldn't because if it did, MCB's and RCD's could not comply with it, as they are not fail safe. This is a major flaw in thinking, and an example of piss poor understanding of electrical safety, because if the MCB or RCD does fail. and after all they are mechanical devices, the only protection left is the mains supply cut out fuse usually rated between 60 and 100 amps, and testing/calculating the "prospective fault current" and filling in the result on a test sheet is not going to stop an overload fire happening. A fuse ALWAYS fails safe! Use MCB's and RCD's by all means, but use fuses as well because they provide protection for the MCB/RCD itself.
The strange thing is that although I am not Part P registered, I am a "competent person" and can still rewire houses (part P ONLY applies to domestic premises) should I wish too. In fact ANYONE can rewire their own house, as long as they get the work checked by the local Bulding control electrical inspector,(it costs!) but they (the householder) have to test it, (not simple anymore and requiring expensive test equipment) and sign it off and accept responsibility for its safety.
So what effect has this cockeyed legislation had?
It has given the larger electrical contractors an excuse to dump all there domestic work. Talked to a NICEIC rep during the introduction of partP period, and he told me that out of twenty contractors he had visited that week, only three had expressed any interest in signing up for part P registration.
It has provided lots of jobs for middle management running the registration schemes (known in the trade as the registration scams)
It has made a fortune for training colleges peddling useless training courses with no hope of a job at the end.
