    Of course, human dernet shock, but no more. By careless handling electrical appliances. Here is a classic example. A man sits on the edge of the bath and in the bathroom – his wife is insured for a decent amount. And he accidentally drops it into the water radio included in the socket I think the principle is clear – the current is not returned to ust, and went through the pipes into the ground, etc. To deepen your understanding PCRM is the source. Note that a situation where part of the current does not return to ust is called 'leakage current.

    ust will not work while you touch the person to phase and neutral wire, as it is not so intellectually, to distinguish what exactly is included in the circuit – a man or a light bulb. If the leakage is not present – all in order. Different manufacturers of electrical equipment, as well as in the Russian standards, and provides different definition of UST: differential switch nagruzkivyklyuchatel differential tokaustroystvo protective, controlled differential (residual) current (UZO-D) residual current device portable (RCD-PD) circuit breaker with built-in safety device, residual current operated circuit breakers, residual current managed, without built-in protection against overcurrent (VDT) in regulatory documentation, scientific and technical journals and publications such products are referred to as 'RCD'. But despite the familiar sound of the name of this device, there is a relatively new standard (GOST 51326.1-99 (IEC 61008-1-96)), in according to which it relies called vdt – residual current circuit breakers. Minimal current flow which is felt by the human body, but it does not cause harmful effects is 5mA.
