Protective equipment for safely discharging electrical potential comprises an interface (10, 50, 60) adapted to be in contact with a wearer. A conductive path in the interface contacts the wearer, the conductive path reaching a ground. A first circuit device (30) is provided in the conductive path. The first circuit device (30) has at least one variable resistance so as to oppose a first level of variable resistance to decrease a conductivity in the conductive path as a function of an increase in potential difference between the wearer and the ground, to allow static discharge through the protective equipment.
