Is there a general rule that one can go by, to know when the NEC specifically requires a GFCI breaker rather than a GFCI receptacle? For instance, 210.8 says circuits shall have ground fault protection for personnel, while 680.22(A)4 says that the receptacle shall be protected by a GFCI. One could theorize that for safety reasons, they may want a GFCI breaker to be used, as this could protect from the shock scenarios that could occur if one touches a metal receptacle box that is filled with water (in this scenario, the GFCI could have tripped and left its supply conductors on, while not being shorted out enough to trip a breaker on overcurrent).
So is it a NEC wide rule, that when it says the receptacle shall be protected by a GFCI, then this means that there is a GFCI ahead of the receptacle?
