Too bloody far for my liking!
Go down to the electrical wholesalers on a Saturday morning & you find Mr (or Mrs) DIY.
Mr DIY: "I want some wire!"
E.W.: "What size?"
Mr DIY: "I don't know, it's for wiring a shower"
E.W.: "You'll want 6 or 10mm then, what's the loading of the shower......etc.

I've witnessed the above on several occasions. Then they go home & wire a nice little death trap for their family & future unsuspecting homebuyers. [Linked Image]

I'm sure you will all be surprised to learn that I don't approve of DIY electrical work!

There is talk of requiring all electrical installations that need a Building Warrant Electrical Completion Certificate to be carried out by a "competent enterprise".
However this is a couple of years away & will only stop DIY work on new installations & alterations where Building Warrant is required.
I think this is a step in the right direction (if it happens), but I would like to see DIY wiring limited to replacing broken accessories only.
I would also like to see all electricians compulsorily licensed.
(Steps down from soap box.)
