you were required to have an isolating transformer type socket in your house before the advent of the RCD, a LOT of houses here built in the 60's and 70's still have them.
I had no idea it was Kiwi practice to do this. Evidently, things were different prior to merging of the wiring rules.
I guess a non isolated/non RCD protected 240V 10A power point in the bathroom must horrify those who haven't grown up with them.
How does one use a hairdryer or portable heater where there is only 20VA shaver outlet?
