Hi there Guys, I had this really strange email just this last week, from a lady that I had never even heard of, she had this question for me: If you are in a bath, and you have a heater or other appliance and it falls into the bath while you are in it, will you get Electrocuted?.(disregard GFCI/RCD protection). Having never tried this out for myself, I would not encourage anyone else to have a go at it, either!!, I was just wondering how a shock would occur?. Could you people please help me with this one, as it is really killing me thinking about it.

One's body, which for this is equivalent to a sack of dirty water with lots of salt and such in it, would probably pass most of the leakage current from the heater. Current would flow from the heater thru many paths in the water (which is likely to be somewhat dirty) to your body, and then thru your body to other areas of the body and exit thru more multiple paths in the water to a grounded faucet and drain hardware. And the porcelin coating on a metal tub is likely to have many small cracks, creating more current paths....
Guys, Sorry about the rather vague question. But assuming that the heater is a Class II appliance (Having Double Insulation, as the majority of Domestic Heaters these days, have an outer shell of plastic). Also assuming that a person was lying in the bath and not touching the plug-hole or the taps(faucets). How would(or could) a shock occur, is it merely by the current flow through the water?. Remember that the current has to flow through the heart, to cause fibrillation, before a true shock would occur. Thanks for your input fella's. I'm still trying to work out how this lady got my e-mail address, let alone work out the actual problem!

There are bound to be currents of some magnitude flowing through parts of the water, but the actual paths and levels are going to be very dependent upon the salt/mineral content of that water, how far away the person is from the energized heater, and so on.
It's not something I'd want to put the test in a practical experiment....
