Yes Rum, but you could also look at all the countries ruuning on 240V, are there considerable deaths on site?

anyway, its the same thing, because:

110V CTE, fault voltage to earth = 55V

230V on an RCD: maximum fault voltage to earth (at a Zs of 1667 ohms) = 50V (before the RCD disconnects), and at lower Zs values, fault voltage to earth will be much lower

so there! its safe! crack on then lads!
