Just one such suit would sure slow down these DIY "enablers."
I couldn't agree more, mate.
If this is the standard of work that they are teaching at these "classes", something seriously needs to be done.
It sort of makes you wonder as well, what sort of wiring standards, some homeowners have inside thier houses, because of poor tuition.
Other side of the coin, you have to also realise that a seminar like this can't teach you everything and I'd be inclined to think that on the majority of occasions where work like this has occured, it's the result of the homeowner either guessing (through lack of knowledge) or substituting the proper parts and equipment for something that they "happened to have handy".
Either way, it's just not good enough!.
