I'm not trying to pick a fight either
Electrican does indeed cover a wide range of skills, to answer one of your earlier posts I would be more than happy to install data cabels, haveing spent 20 years in IT support, fire alarms no i don't think I'm competent to do that at the moment although if I got the chance I would learn the rules and regs fairly fast.
I think the point I am trying to make is that "You have to be competent" but there is no real definition of competent
Its fairly easy to prove someone is not competent "the house goes up in flames", but much harder to prove they are competent "the house has NOT gone up in flames, YET".
I dont think the people on my course where a set of muppets, I think in 90% of cases they would do a very good job, what worries me is the 10% when they dont have the knowledge to realise that its an exception to the rules.
What also worries me is the view that an apprenticeship makes you an electrician (or a plumber, or a carpenter, or a brain surgoeon), we all know that a lot of people did there "time" putting up conduit or trunking.
5 years of putting up conduit does not make you a sparkie, nor I would add does 3 years of takeing exams, you need the combination of both.
