55 Volts either side of earth is quite reasonable (like site power 
tools, and much of the Americas).  It's generally much safer, though 
heavier current devices usually require higher supply voltages - it's 
not uncommon for most domestic supplies to be 110V (55V either side of 
earth) with an additional 230V supply for washing machines, air 
conditioners and the like.
