When the transfer switch interrupts the load from one source, currents in the individual lines and neutral may not all clear at the same instant. It's possible that current in the neutral conductor, which is usually less than the line currents, will clear first.
What causes a receptacle to disconnect?
Consequently, any fault or inadvertent current path between the frame and a phase conductor will cause the receptacle to disconnect. When the premises wiring is connected to the gen-set, the neutral becomes effectively grounded when the neutral conductors are connected.
What is zero sequence GFP?
Keep in mind that a zero-sequence GFP acts when it senses a predetermined value of current imbalance. So, the current following Path 2 will pass through the transformer GFP sensor just as though it were normal load current, and the zero-sequence GFP will sense only the fault current following Path 1.
