Czech domestic power system is 220 volts with standard continental
two pin plugs and three pin plugs (with earth) with round prongs
are used. A two pin plug will fit in a three pin socket.
Canadians with 110V equipment will need a transformer which changes
the voltage and an adapter to fit Czech sockets. These can be bought
at any hardware store. British, Australians and South Africans can
use a plug adapter which most department stores stock.
