Hi
I have received conflicting information regarding who can fit and wire up a replacement geyser in a house. ie if your geyser bursts and it requires replacing, can a plumber do the whole installation including the wiring, or does one need an electrician to attend to the electrics.

The understanding is that a plumber can work from the isolator at the geyser to the geyser without an electrician required to be present.

Anyone with knowledge of the regulations I would appreciate some insight.
