Two GFCI Circuit Breakers in One Subpanel
Hello, new to this forum and really like it!
I just purchased a new Siemens QF220A Ground Fault Circuit Interrupter, 20 Amp, 2 Pole, 120V, circuit breaker to replace the existing non-GFCI 20 Amp, 2 Pole, 120V for a new Pentair Intelliflo VS pool pump.
When I opened my sub-panel I noticed there was already a GFCI 15 Amp, 1 Pole, 120V breaker installed for the pool light. The instructions for installing the Siemens QF220A Ground Fault Circuit Interrupter, 20 Amp, 2 Pole, 120V, circuit breaker require only one GFCI connect to the common neutral bar at a time.
Not sure what to do at this point as both breakers need to be GFCI. Is there a certain way to wire the two GFCI breakers together? Added a picture of the sub-panel.
Thanks in advance,
CMAC

Welcome to the forums.
I'm seeing some issues there....
Why are there two white wires on the GFI breaker for the light ?
I see the two black wires wirenutted together. If that light has a remote switch..... it's not wired correctly.
You can use two GFI breakers in that panel but you will need multiple neutral terminals in an insulated neutral bar. I can't see how the neutrals are handled now.

I do not know who wire it as this was the first time I open the panel. What is the best way to handle this issue? I have updated the pic. Thanks.

The white wire is marked as black. Leave it for now.
I see the neutral bar in your second picture. You should be all set.

So I just need to add an insulated neutral bar and remove the old 2-pole breaker and replace it the new Siemens QF220A Ground Fault Circuit Interrupter, 20 Amp, 2 Pole, 120V, circuit breaker?
Thanks

I still need to replace/install the new Siemens QF220A Ground Fault Circuit Interrupter in the panel. How do i do this with isolated neutral bar?

You connect your two load lines to the breaker and the neutral tail to the neutral bar.
The terminal marked neutral on the breaker will remain empty.
