[RFI] Inquiry - AFCI RFI?

[Gene Smar]

Gents:
     I'm having my electric service panel in our home replaced and wanted to ask if any of you have had experience, either good or bad, with code-required arc-fault circuit interrupters and related RFI?  I believe I read somewhere that either these or GFCI's were problematic in generating RFI, especially on the lowbands.  I'd like to make sure I don't make things worse for myself by allowing the electrician to install the wrong AFCI design or brand.  I've also read that AFCI's often trip unnecessarily.  Any comments on that aspect as well?  

     Many thanks.
