Ground Fault Protection and its Purpose
GROUND FAULT PROTECTION, ITS PURPOSE. GROUND FAULT PROTECTIVE DEVICES OUTLETS AND CIRCUIT BREAKERS, OPEN UP THE CIRCUIT(TURN IT OFF), WHEN THEY DETECT A SMALL AMOUNT OF CURRENT FLOWING ON THE GROUND. THEY CAN EVEN DETECT THIS WITHOUT THE BARE WIRE EVEN BEING PRESENT. BY ELECTRONIC CALCULATION OF ANY IMBALANCE BETWEEN THE “HOT” OR PHASE WIRE AND THE “NEUTRAL” WIRE. YOU SEE IF THERE IS ANY DIFFERENCE IN CURRENT BETWEEN THE TWO WIRES THE DEVICE DETERMINES (CORRECTLY ) THAT THE ENERGY IS GOING TO GROUND. IT THEN SHUTS OFF. THE USUAL SETTING OF THESE DEVICES IS FIVE MILLIAMPS. THAT ONLY FIVE ONE THOUSANDS OF 1 AMP! 0.005 AMPS!
