Incidentally, a toaster in the bath would blow the fuses in your house before it could kill you - it's a form of device protection.
This is not true. I have witnessed a blow dryer being dropped in a 10 gal fish tank for an EE class safety experiment (we were doing NEC/safety/and other codes).
The blow dryer paddled water like nothing had happened without the GFCI installed. With the GFCI the circuit tripped immediately. It is the main reason why most portable electrical devices such as hair dryers and curling irons have GFCIs built in to the plug.
Most common US breakers are rated for 20A. It only takes about 0.01-0.02 A to cause death. A common house breaker wouldn't skip a beat if you jumped a line. The body has just too high of a resistance to draw 20A of current.
Now if the house was up to code a GFCI circuit would be installed in the kitchen and all bathrooms (outside areas too). This is the best way to trip a circuit if a person gets hung on the line.
Sorry for off topic.
