I have a friend in the UK who insists that many of the light switches his company stocks there will work in Australia, and that clipsal units etc are essentially the same. It's tempting to buy some from him because a) he's offering them to me at his price which is very cheap and b) they look very nice. The dimmers are specified at 220v to 250v range.
However, when a sparky arrives at my house and sees these switches and my installation plan, will they point out the error of my ways and force me to go with the uglier HPM superdimmer or equivalent? Better to know in advance.
