Commercial GFCI and AFCI

[fnewman (Frank P. Newman)]

In what locations are GFCi and AFCI devices required in commercial buildings, based on the most recent code revisions? TIA

AFCI protection is required when the commercial buildings contain dwelling units. GFCI protection is as follows from the 2014 NEC:

(B) Other Than Dwelling Units. All 125-volt, single-
phase, 15- and 20-ampere receptacles installed in the loca-
tions specified in 210.8(B)(1) through (8) shall have
ground-fault circuit-interrupter protection for personnel.
(1) Bathrooms
(2) Kitchens
(3) Rooftops
(4) Outdoors
Exception No. 1 to (3): Receptacles on rooftops shall not be
required to be readily accessible other than from the
rooftop.
Exception No. 2 to (3) and (4): Receptacles that are not
readily accessible and are supplied by a branch circuit
dedicated to electric snow-melting, deicing, or pipeline and
vessel heating equipment shall be permitted to be installed
in accordance with 426.28 or 427.22, as applicable.
Exception No. 3 to (4): In industrial establishments only,
where the conditions of maintenance and supervision en-
sure that only qualified personnel are involved, an assured
equipment grounding conductor program as specified in
590.6(B)(2) shall be permitted for only those receptacle
outlets used to supply equipment that would create a
greater hazard if power is interrupted or having a design
that is not compatible with GFCI protection.
(5) Sinks — where receptacles are installed within 1.8 m
(6 ft) of the outside edge of the sink
Exception No. 1 to (5): In industrial laboratories, recep-
tacles used to supply equipment where removal of power
would introduce a greater hazard shall be permitted to be
installed without GFCI protection.
Exception No. 2 to (5): For receptacles located in patient
bed locations of general care or critical care areas of
health care facilities other than those covered under
210.8(B)(1), GFCI protection shall not be required.
(6) Indoor wet locations
(7) Locker rooms with associated showering facilities
(8) Garages, service bays, and similar areas other than ve-
hicle exhibition halls and showrooms

LOL, that’s a ghost in the machine. For some reason the forum software subtitles smiley for the number 8.

It’s the combination of “8” + “)” that creates the smiley.
