          I have a GOULD I-T-E Indoor Loadcenter G1224ML1125. I need to replace a GFCI breaker QF-120. Is the Siemens QPF2N a suitable replacement?

          1 Answer | 
          Answer This Question

          The QF120A would be the approved replacement.

            My question was about using this breaker in a box requiring a QP or QPH breaker. The answer I got was what I could use in a box needing a QAF or QPF. Is there a CI type that I can use in my box?
            ByDec 16, 2024
            1 Answer | 
            Answer This Question

            No you cannot use this type of breaker because your label on the panel door is not marked with types QAF or QPF then unfortunately the dual function CAFCI/GFCI breaker will not work. Without knowing the part# of your load center we cannot confirm which AFCI or GFCI breaker is accepted in your unit.

            By|Dec 18, 2024


              My load center call for QP or QPH(?) breakers. Will this breaker work in that panel?
              ByDec 12, 2024
              1 Answer | 
              Answer This Question

              No this dual function breaker is for plug on neutral loadcenters if your panel designates QAF, QPF you can use the QFGA2, QFGAH2, HQFGA2 like Q120DF

                Is this the breaker that has the Lock Out feature? If so, how does the homeowner go about resetting it?
                ByDec 11, 2024
                1 Answer | 
                Answer This Question

                Q120DFN does not have a lock out feature built into the breaker. If the breaker trips, you would move the handle to the off position and then move the handle to on position to energize the breaker.

                    The breaker was exactly what I needed, and as described when it arrived. Install went perfectly.

                    I swapped out a gfci/arc fault for this gfci only unit because my microwave oven kept tripping the original. No problems since. I like the plug on neutral system because it makes installation easier.
