FIELD: electric engineering. SUBSTANCE: when electric appliance is disconnected from protected de-energizing device, current runs through working circuit of electric appliance so that level of this current is safe for human. Current level in appliance circuit that is connected to appliance housing is controlled. If current level in this circuit is below pre-set level when device can be turned on, device is supplied. Level of current when electric power is turned on is significantly less than level for protected de-energizing. Current clippers are connected in parallel to terminals of device. These terminals are connected to supply line and working circuit of electric appliance. EFFECT: increased functional capabilities. 2 cl, 2 dwg
