Part of my project is going to include installing a few flood lights (x10), wall switches and powerflash module out to my shed.  Will give a little backround to help answer my question.

She is going to be fed from main panel to a 60amp sub panel.  There will be 2 15amp breakers and 1 20 amp gfci breaker.  The 20 amp gfci breaker is being put in for a pool pump that is going to be installed at a later date.  I plan on putting in an x10 pro outlet for the pool pump off the gfci breaker so that I can turn the pump on/off when I want.

Will I run into any issues with this setup, specifically the gfci side.  I have read that some gfci's absorb the x10 signal.  Has anyone installed any gfci breakers without issues?  If so what brand?  The current plan is to use Square D QO series since that is also what's installed in my main panel.

Any suggestions or comments?  Any issues I should be aware of or things I should change.

Oh, and if I should put these types of questions in a different area, please let me know.

As you said "some" GFI's will not pass X10 signals. The good news is I have Square D panel with 20A GFI breaker feeding outside outlets...no problems, all the modules on that circuit work fine. I don't know what series breaker I have (the panel is 1970ish) but would imagine internally they would be similar. AFIs are a different matter and do kill X10, (that isn't meant to be an all encompassing statement...maybe some do not interfere with X10)  so avoid an arc fault /ground fault combination breaker.

Thanks Dave!

Our landscape lights are also fed through a 20A Square D GFI breaker with no problem (even running barefoot without XTB boost).  And the Square D Arc Fault that feeds my office/lab similarly passes X10 signals just fine.  I use the RF transceiver at the opposite end of the house when testing weak signal reception in my lab.  Both the Square D GFI and Arc Fault were bought several years ago.

Thanks Jeff. interestingly it was a Square D AGFI that stopped my X10. But if I understand how the AFI works, I can't think of why it would block X10. I took the breaker back for  exchange for simple GFI, they are too expensive to tear-up "to see what's inside".

Thanks guys.  Hope that these type of questions aren't too noobie-ish.  Have another question that I'll create a new post about.  Have my parts list finalized now.
