WebThe 3 wire method of no-trip loop testing has become the norm over the past 20 years. This test method overcame the need to by-pass even the new electronic protection devices by utilising a low current Line-Earth test current, whilst still returning a degree of accuracy. Not having to by-pass the RCD/RCBO obviously introduced a time saving factor. WebThe earth loop impedance test creates a temporary low resistance path between live and earth for the duration of the test. This is particularly hazardous with both an instrument fault and an installation fault. Working practice and hazard avoidance must take care of this risk.
