Abstract: Nuisance trippings of residual current circuit breakers (RCCBs) or ground fault protectors (GFPs) are frequently experienced in environments supporting computer and electronic type loads. This paper discusses the causes of these problems and identifies high levels of earth leakage currents through filter capacitors present in the power supply circuits of these loads as a major reason. A new special dedicated earth return scheme used with a special RCCB which can overcome this effect is offered. © 1990.
