Hello Pauluk,
I will answer to your query regarding regulation on GFI protection to Feeders
Here we can either provide GFI protection at feeder end or at the final end circuit distribution board.It is a matter of convenience .Normally for small installations like the one in question we have
Over current and short circuit protection of high breaking capacity at main feeder.

Over current and short circuit protection of lower breaking capacity + GFI protection at Distribution board end.

Whereas for larger installations we do have at main feeder end earth fault relay operated CIRCUIT BREAKER (ACB or others) with thermal magnetic trip.
