Paul,
Whether the rules which are in place (re connecting homeowner's work) are right or wrong, what strikes me as being completely crazy is that the EWRB should start attacking a sparky for simply following those rules.
I hate to say it mate, but this is the down-side of self-certification.
This is why I am all for going back to the old system of Power Board Inspectors and real Documentation of what is happening with wiring in Domestic places here.
Unfortunately, when signing your name on a CoC, you are in fact certifying
all of the work in the house, that happened since the last registered person visited, if one did at all.
If someone gets a shock or the house catches fire after you certify, it is up to
YOU to prove that you had nothing to do with the said incident.
BTW, Self-Certification was bought in to make things cheaper for the consumer and the Electrical Contracting Industryas a whole.
Just like power here was supposed to get cheaper.
Boy, someone mucked up thier calculations.
