[QUOTE="apprentice87, post: 499073, member: 13534"] I suppose the figue might vary as you say, but i would imagine that the 22,000 ohms figure gives enough margind for some changes.. This figure is chosen so that as can be seen by dividing 230/22,000 = 0.010 the shock a perosn would get would only be about 10 mA. This is apparently the level of shock that can be felt but is well short of the 30mA that is deemed to be the "safe level" So far as i know, in palces where persons may be all wet and so make better contact with the extraneous part the figure would be raised to more like 40,000 ohms... john..
