Connecting Up For Intermittent/Nuisance Trips

"Intermittent trips are circuit breakers rightfully operating because of an unknown cause or fault. Nuisance trips are a breaker deeming a non-existent fault has occurred and, in so doing, operates without need."

"Earth leakage currents arise mainly from the EMC filters built into electronic equipment with switched mode power supplies. Standards limit the leakage current from non-fixed equipment (i.e. equipment that plugs into a standard socket outlet) to less than 3.5 mA. When a lot of electronic equipment is in use, the total leakage current in the protective conductor can become significant."
