The discussion of double insulation reminded me of a question posed to me, so I thought I would enquire here:
A friend, going to Argentina on business, asked what type of plug adapter she needs for her dual-voltage (120-240) appliances -- hair dryer, steam iron, and Mac laptop. She has a two-prong plug adapter for Australia.
Kropla.com says the Argentinian plugs are the same as Australia, except active and neutral are switched.
First, I thought only in North America do we have "active" (line) and neutral. What does active and neutral mean in Australia and/or Argentina?
Second, her appliances are all two pronged, but the have polarized plugs. The hair dryer has some sort of circuit breaker integral with the plug.
Is there any way she could use her Australia plug adaptor in Argentina without creating a shock hazard?
