Re: GFCI Breaker Question
It all depends on the leakage to ground. For example XHHW-2 is better insulation than THHW and will have less leakage. Assuming the breaker and receptacle are both class A devices there should be no difference in distance.

Re: GFCI Breaker Question
Is the 90 foot distance off the load side of a GFCI receptacle a fact or field assumption? I have never seen that in print before.

Re: GFCI Breaker Question
what is the reason for the distance limitation? will the gfci nuisanmce trip?

Re: GFCI Breaker Question
I believe that this is a design issue not a code issue.
Look back at Tom's post, he summed it up nicely.
Here is what Square D says about the installation of type QO Class A GFCI Breakers
"To minimize nuisance tripping" the way I read that is you may ignore these recommendations but that may result in nuisance tripping.
I have done many jobs that get beyond 250 one way on GFCIs, typically for heat trace circuits on process piping.
IMO, a better design has the GFCI as close to the outlet or equipment it serves but it is not a code requirement to do so.

This quote was taken from a Square D web site, I tried linking to it but it would not work, if you want to see it I will email the address to anyone.
