2011 NECHB 210.8(C) commentary

[chris kennedy]

Blue highlight below is the commentary, red is the point of interest.

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

The proximity of this type of equipment to water and the wet
or damp environment inherent to the location in which boathoists are used is the reason for this GFCI requirement. Documented
cases of electrocutions associated with the use of
boat hoists compiled by the U.S. Consumer Product Safety
Commission substantiated the need for this requirement.
The requirement applies only to dwelling unit locations, and
GFCI protection must be provided for boat hoists supplied
by 15- or 20-ampere branch circuits rated 240 volts or less.
It is important to note that in contrast to the requirements in
210.8(A) and (B), 210.8(C) applies to all outlets supplied
from 15- and 20-ampere, 120-volt branch circuits, not just to
receptacle outlets. Therefore, both cord-and-plug-connected
and hard-wired boat hoists are required to be GFCI protected.

So my question is, where in 210.8 would the commentary authors find this requirement applies only to 15-20A hoists?
30A and I don't need GFCI?

Thanks

I agree with your point.
The earlier sections of 210.8 specifically apply to only 15 and 20 amp circuits, but the section on residential boat hoists (i.e. dwelling unit locations) does not have any such limitation.

Probably because most residential hoists are not rated more than 20 amps but I believe they took it for granted. IMO, a 30 amp cir would also need gfci protection.

It doesn't say that other than 15 amp and 20 amp do not require GFCI protection.

Probably because the editors never changed the commentary when the 2005 wording of "125 volt, 15 and 20 ampere circuits" was changed in the 2008 code to say "outlets not exceeding 240 volts".

That seems to be somewhat of a sporadic problem with the NECH commentary.

Yes, we have that issue with the commentary in the 2014 handbook, saying that dwelling unit dishwashers don't need GFCI protection, yet there was a new rule added in the 2014 code to specifically require dwelling unit outlets that serve dishwashers to have GFCI protection
