NEC Handbook error on Boat Hoist GFCI protection?

[Charlypt]

We have installed several boat hoists in the past and always supply the system with GFCI protection. But the other day we were installing some 30A motors and one of the electricians showed an NEC version (2017 Handbook) and said that in this case the code states that it does not require GFCI protection.
I had always used the normal code, not the handbook, where article 210.8 (C) is applicable for Boat Hoist, without discussion; but in the Handbook there is an additional note that says:
"The GFCI requirement applies only to dwelling unit locations and to boat hoists supplied by 15- or 20-ampere branch circuits rated 240 volts or less."
This is going to sound crazy, but if our motors are 30 A, does that mean they are excluded or is this a bug in the Handbook code?

It does only apply to dwelling units however I don't see where 15-20 amp is applicable.

nec 2018

210.8(C) Boat Hoists. GFCI protection shall be provided for
outlets not exceeding 240 volts that supply boat hoists installed
in dwelling unit locations

Note that while the Handbook commentary is normally spot on it is not code.

This what I said. Thanks.

Check the Handbook.

Documented cases of electrocutions associated with the use of boat
hoists compiled by the U.S. Consumer Product Safety Commission sub-stantiated
the need for this requirement. The GFCI requirement applies
only to dwelling unit locations and to boat hoists supplied by 15- or
20-ampere branch circuits rated 240 volts or less. It is important to note
that it applies to all outlets, not just to receptacle outlets. Therefore, both
cord-and-plug-connected and hard-wired boat hoists are required to be
GFCI protected.

but they should fix it because these should be explanatory notes, not to introduce confusion.

They probably should but the actual code sections between 210.8(A) and 210.8(C) is the real culprit IMO. "Boathouses" should not be in 210.8(A), 210.8(C) covers it completely.

I've got to regroup. Boathouses and Boat hoist are not the same thing. 210.8(C) stands alone and would require GFCI protection for all hoists but not all boathouses, my misstake.

I suppose they can refer to Boathouse without Boat Hoist, talking about receptacles only.

You are fast.

In the 2023 the GFCI requirement applies to all boat hoist outlets not exceeding 240 volts, not just hoists at dwelling units as in the previous codes. Also the rule was moved to Article 555 in the 2020 because the scope of 555 was expanded to include docking facilities at dwelling units.
