First, I am not an expert but have studied the situation fairly closely.  A GFCI BREAKER at the service panel should protect anything down that line.  In my case I dug a trench and ran UF cable underground (at least 18 inches) from an unprotected circuit under a corner of the cabin to a night light near the waterfront on a post.  From 12 inches underground at the light post the UF cable is encased in pvc to the GFCI outlet.  I used a waterproof outlet box, and from the GFCI receptacle PROTECTED SIDE ran two lines, one, encased in pvc to the light, the other via UF through PVC pipe to an outlet on the dock.  BTW, UF stands for underground feeder and is cleared for buried or overhead use without the protection of metallic or non metallic conduit.  Cable rated NM-B SHOULD NEVER be used in either such case.  It is for interior use or under a house where there is no threat of it getting wet.

My curiosity about GFCI was aroused when we moved into our present house in Montgomery and experienced outlet outages in the master bath during exceptionally heavy rains.  Found that to restore service we had to reset the GFCI outlet IN THE GARAGE.

If there are any real electricians out there I would be curious to know that, even though the link from the house to the light post is IAW code, would it be better to move the GFCI box to the point that the circuit leaves the house?
