Square D™ QO230GFI

• Qwik-Gard GFCIs provide the same branch circuit protection as standard QO circuit breakers
• They are longer than standard QO circuit breakers, and thus require more gutter space
• Class A devices must trip at 6 mA of ground-fault current and above, and hold below 4 mA of ground-fault current
• For use with QO load centers, NQOD panelboards/interiors and Speed-D switchboard distribution panels
• 14 to 10 AWG copper, 14 to 8 AWG copper/aluminum
• Common trip
• Ground fault protecting class A 6 mA

The ground-fault sensor in a Qwik-Gard GFCI continuously monitors the current flow in the load and neutral conductors. The sensor compares the current flow in all directions. If the current flowing back to the source is less than the current flowing out to the load, a ground fault exists. When the difference in current flow exceeds 6 milliamperes, the sensor sends a signal to trip the GFCI. The trip will be indicated by the Visi-Trip® indicator and the operating handle will move to the center tripped position.
