Barry,

Thank you,

Where this matches the final 2008 NEC I find it a bit easier to copy and paste from, also, there are some nice diagrams.

Am I understanding this to mean that garage door "inaccessible" opener outlets are to be GFCI protected?

11
Article 210
Section 210.8 (A) Ground-Fault Circuit Interrupter Protection
for Personnel; Dwelling Units.
The exception numbers (1) and (2) have been removed and GFCI protection is now
required for most receptacles in unfinished basements and in garages and accessory
buildings that have a floor located at or below grade level not intended as habitable rooms
and limited to storage areas, work areas and areas of similar use.
(1) Receptacles that are not readily accessible
(2) 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 in accordance with
400.7(A)(6), (A)(7) or (A)(8).
Analysis of Change:
Lack of “accessibility” of receptacles in these areas is no longer seen as reason to exempt
them from the protection provided by ground-fault circuit interrupter protection for
personnel. Similarly, the exception for receptacles in dedicated spaces for appliances in
garages and accessory buildings has been removed. The expanded use of GFCI
receptacles in these applications will necessitate boxes having larger capacity in some
cases. Exception number (3) was retained for a receptacle supplying a permanently
installed fire alarm or burglar alarm system.

Yes.

*Most* of the previous Exceptions to GFCI protection have been removed. For all dwelling unit locations.

For example, the exception for GFCI protection not being required for 'appliances' (i.e., freezer and refrigerator) are also gone.

The reason for some (like the one on the ceiling for the garage door opener and other high ones considered "not readily accessible") the reason is that taller people should be afforded the same protection as shorter people. Makes sense when you consider that there is no reason to protect a shorter person and let a taller person be electrocuted.

The reason for some (like the appliances) is that appliances have, for quite some time now, been being manufactured to a higher standard regarding ground leakage, i.e., less ground fault current is allowed, making it such that when an appliance trips a GFCI - that indicates a problem with the appliance. That's what I've been saying here the last few years, and the reason why sump pumps were not given an exception (the sump pump motor was not allowed to have enough ground fault leakage to trip a GFCI, and, if it did, then there is a problem with the sump pump or its circuit).

On the subject of GFCI protection in a garage, are there any new (or old) requirements or even suggestions to prevent tripping of a freezer circuit from a remote location or to provide accessibility to reset the GFCI without moving the appliance? I am thinking of the typical set-up here where the front and rear exterior outlets are protected by the GFCI in the garage. I always tell people not to use the GFCI outlet so they don't loose the freezer full of meat when the Christmas lights on the front porch outlet trip the GFCI in the garage while they are gone for the weekend, etc.
Common sense can't be relied on for the electrician to put in a separate circuit for this, anything in the new codes address this?

That'll work as long as I get enough donations between now and then

As Jerry P stated per 2008 NEC code changes, ALL receptacle outlets within a garage shall be GFCI protected. NO exceptions !

Jim Luttrall · #10 (**permalink**) 11-24-2007, 02:38 PM

Jerry M., I got the ALL are required to be GFCI part. My question was if there are any additional rules or footnote advice to require a separate GFCI circuit for freezer spaces, etc.

BARRY ADAIR · #11 (**permalink**) 11-24-2007, 05:12 PM

Jim,

This may cover the answer you're looking for

Garage. A garage attached to a dwelling unit must have a receptacle [210.52(G)]. In an accessory building or a detached garage with power, a receptacle is also required. In either case, the receptacle must be GFCI protected [210.8(A)(2)]. A couple of exceptions exist:

Receptacles that aren't readily accessible, such as those in the ceiling for the garage door opener motor. See the definition of “Readily Accessible” in Art. 100.

A single receptacle on a dedicated branch circuit identified for a specific cord-and-plug connected appliance, such as a refrigerator or freezer. You can use a duplex receptacle without GFCI protection for two such appliances. Receptacles permitted by this exception must be within 6 feet of the appliance [210.50(C)].

Receptacles that aren't readily accessible (or those for a dedicated branch circuit for a specific cord-and-plug connected appliance, as permitted in the two exceptions above) do not count as the required receptacle described in 210.52(G).

Branch Circuits - Applying GFCIs and AFCIs

BTW if it does answer correctly you're buying lunch I'm not as easy as Rick and am not Kiddin'

Barry, close but no cigar. I guess that means you are stuck buying

I just finished reading through your post of NEC changes for 2008 and found no new requirements to prevent accidental loss from GFCI trips for refrigerators and freezers.

On a related note, given the expanded role of AFCI it seems that all outlets under the 2008 code will be either AFCI or GFCI protected. Does anyone know the reason that kitchens an baths do not require AFCI protection (yet)?

BARRY ADAIR · #13 (**permalink**) 11-25-2007, 04:42 AM

Jim,
If this is true and thus being the case, all of the refrigerated and frozen food that was intended for lunch has been lost from a nuisance trip during the storms we are having and lunch will be PBJ sandwiches at the park.

got milk?

Michael Larson · #14 (**permalink**) 11-25-2007, 08:58 AM

Wisconsin adopted the 2005 NEC but modified it to exclude any AFCI requirements.

We will see what happens when it comes to the 2008 NEC.

JM Comments: I fail to see any exceptions. Also, the new GFCI devices now available are not nearly as susceptible to nuisance tripping as older versions
BTW – how did we get on AFCIs?

Barry,

*NO* exception exist for 125 volt 15 and 20 amp receptacle outlets in the Garage (or an accessory building) - *ALL* "Exceptions" have been removed.

Probably the BAD INFO link I posted

Jerry P

Got that at Jim's posts but thanks to all for the reaffirmation.

Stay out of this

There is no mention in the 2008 of circuits for "exterior" outlets, thus, you could wire a house with one or more circuits for "exterior" outlets and *NOT* be required to have AFCI protection.

Was that a miss on their part? Or was it intended? I don't know, but it would allow non-AFCI protected 125 volt circuits to be "within" the dwelling unit so long as the "outlets" on those circuits were not in the dwelling units.

I am puzzled by all this interest in the 2008 NEC. Why are HI's interested?

After all, codes are NOT retroactive. The 2008 edition can be applied only to those projects whose plans were approved after the 08 edition was adopted by the local jurisdiction. I am not aware of any jurisdiction having yet adopted it.

Add to this the idea that HI's don't inspect new construction ... and I would expect this discussion to lay dormant for another year or two.
