Another point about self-certification, here at least, was back in 1992, we were told by the EWRB that we had the option of this or having a rolling Audit system.
Little did we know that the two would be combined in 1995.
But, like all things, guys, at least as far as us guys go here, it only catches the honest Electrician.
I use the term Electrician, to denote those of us that can be bothered to sit exams, have done thier time, have things like licences and work within a safe sort of manner, with thier work.
Anyone that likes to work in a Rip, **** and Bust, manner, doesn't deserve the label of an Electrician, it is a title that is earned, not a given.
Self Certification, by rights, should weed that lot out, through the Audit system. [Linked Image]
