Abstract
A power safety device comprising a controller, a load monitor and switching circuitry, wherein the switching circuitry is operable in a first operation state in which a power supply side and a load side are connected by a lower impedance power conduction path or a second operation state when impedance between the load side and the power supply side is high so that hazardous operation current is prevented from flowing from the power source side, through the switching circuitry, and to the load side, wherein the load monitor comprises circuit arrangements to determine and/or monitor load condition on the load side and the controller is to operate the switching circuitry to operate in the first operation state upon detection of a non-hazardous load condition or a predetermined safe load condition on the load side.
