- A receptacle in an accessory building, an implement shed, or even a storage shed also requires GFCI protection. Sometimes an appliance such as a food freezer or refrigerator is located in a garage, and where such an appliance is plugged into a GFCI receptacle, nuisance tripping of the GFCI device could cause food to spoil. Therefore, it is common to have some appliances supplied by non-GFCI circuits. Where a space is dedicated for a cord- and plug-connected appliance that is "not easily moved", the receptacle in such space can be non-GFCI protected, but it must be a single receptacle. If a duplex receptacle were used, an extension cord could be plugged in to the vacant receptacle and used to supply power for hand tools, trimmers, etc. A non-GFCI protected duplex receptacle could be used in a garage in a space dedicated for two appliances that are big enough to be considered "not easily moved"; each appliance would be supplied by one of the receptacles on the yoke of the duplex receptacle. Receptacles described by the term "not readily accessible" are garage door opener receptacles. It is not likely that these receptacles would be used to supply power for hand-held tools and other cord- and plug-connected equipment.

I know what you are thinking ... "BUT, Jerry, that *IS NOT* for "unfinished basements", well, just hold your horses there a minute.

All 125-volt, single-phase, 15- and 20-ampere receptacles installed in unfinished basements shall have ground-fault circuit-interrupter protection for personnel. For purposes of this section, unfinished basements are defined as portions or areas of the basement not intended as habitable rooms and limited to storage areas, work areas, and the like.

- - 1. Receptacles that are not readily accessible.
- - 2. A single receptacle or 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.
- - 3. A receptacle supplying only a permanently installed fire alarm or burglar alarm system.

- Masonry and concrete can provide a conductive path to earth. Bare concrete or masonry walls might be subject to moisture. Where a basement masonry or concrete wall has a framed stud wall in front of it, it should not be considered a damp location, because any cable installed in the wall framing would not be in contact with the bare masonry or concrete. Review the definition of "damp location" and also the allowable applications for wiring methods in Table E3701.4. There is no detailed description of what constitutes "moderate degrees of moisture" from the Chapter 34 definition of damp location.
- The exceptions are the same as for receptacle in a garage that are not readily accessible or are dedicated for an appliance or two appliances. (Jerry's note: Go back up and read the commentary for those one or two receptacles at garages.)
- A single receptacle (not a duplex) supplying a plug-in transformer for an alarm system is exempt since the receptacle is occupied, and nuisance tripping could disable the alarm system.
