Private boat dock: When is GFPE required?

[HomeInspectorKenton]

I thought receptacles on a boat dock were supposed to be GFCI-protected, but NEC 555.35 (A) (3) says that dock branch and feeder conductors should be GFPE. NEC 555.33 (B) (1) Calls for GFCI at locations other than shore power.
I'm confused. What dock receptacles need GFCI protection and which GFPE? receptacle needs GFPE protection?

Do you know the difference between the two types of protection?

All overcurrent devices that supply the dock will have GFPE. Receptacles, other than boat shore power will be GFCI.

Does anyone make a 2 pole 60 amp GFPE? If so what ma trip level? To be used for shore power.

SquareD does. I expect the other manufacturers do also.

Is it a 100ma trip device?

Thanks

If there are multiple shore power receptacles it would likely be a good idea to use a 100ma breaker for the feeder and 30ma on the individual shore power receptacles. (The 100ma allowance is covered by a TIA for 2017 TN Code)

I’m having trouble locating the 100ma device. 50-60amp breaker will work. Shore power cable is 4 wire #4 copper.
