210.8(A)(2) & (A)(5) Exceptions No. 1 and 2 Deleted. All 125-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in (1) through (8) shall have ground-fault circuit-interrupter protection for personnel. The exceptions for not readily accessible and the exception for a single receptacle or a duplex receptacle for two appliances located within dedicated space for each appliance that, in normal use, is not easily moved from one place to another and that is cord-and-plug connected have been deleted. There are still two exceptions included. One is for receptacles located outdoors for snow melting equipment that are not readily accessible, and the other is for unfinished basements for permanently installed fire or burglar alarm systems. Others than these two exceptions all receptacles installed in bathrooms, garages and accessory buildings with a floor at or below grade level, crawl spaces, receptacles in kitchens that serve countertop surfaces, laundry facilities and wet bar sinks where the receptacle is within 6 feet of the outside edge of the sink, and boathouses are required to have GFCI protection.

210.8(B) Other Than Dwelling Units. This section has been revised to now requires that All 125-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in (1) through (4) shall have ground-fault circuit-interrupter protection for personnel:
(1) Bathrooms
(2) Kitchens
(3) Rooftops
(4) Outdoors
Exception No. 1 for dedicated branch circuits for electrical snow melting or deicing equipment remains, and a new Exception No. 2 has been added.
Exception No. 2 For outdoor receptacles in industrial establishments where conditions of maintenance and supervision ensure that only qualified personnel are involved an assured equipment grounding program 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.
Question: For non dwelling units except for out of doors' snow melting or deicing equipment and in nonindustrial locations, receptacles located in the following locations shall have GFCI protection.
