Thread: commercial kitchen GFI

  1. #1

    commercial kitchen GFI

    I was wondering if someone could clear up how the definition of a kitchen is worded in NEC 2005 210.8(B) "other than dwelling units". This section references the installation of GFCI protection in commercial or industrial kitchens. It defines a kitchen as " an area with a sink and permanent facilities for food-preparation and cooking". The text also makes clear that a sink must be installed in the food-preparation area for this section to require GFCI protection of the receptacles in these areas. Okay, so my question is how far does that area extend, does the 6 foot rule apply as it does in a dwelling unit?

    There is no '6 foot' rule for either dwelling units or non-dwelling unit kitchens.

    For dwelling units

    210.8(A) Dwelling Units. 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.

    (6) Kitchens — where the receptacles are installed to serve
    the countertop surfaces
    That is all of them serving the kitchen counter top regardless of the distance to water.


    For non-dwellings

    210.8(B) Other Than Dwelling Units. All 125-volt, singlephase,
    15- and 20-ampere receptacles installed in the locations
    specified in (1) through (5) shall have ground-fault
    circuit-interrupter protection for personnel:


    (2) Kitchens
    That is every one in the kitchen, there are no exceptions.

    No 6' rule, it applies to all 120 volt receptacles in a commercial kitchen. Even the ones protecting the refrig or freezer with the thousands of dollars worth of Filet Mignon and lobster.

    As far as our requirement, using a fast food resturant as an example, we consider everthing behind the counter as "kitchen/food pre", other than places such as offices, walk-in's and what not.
    I can build anything you want if you draw a picture of it on the back of a big enough check.

    There's no substitute for hard work....but that doesn't mean I'm going to give up trying to find one.

    The key word in the definition of a kitchen as per NEC - AREA

    The AHJ can determine, as Cowboyjwc has mentioned above, that the whole room may not be mandated as a kitchen, but an area/portion of it may be the kitchen.

    The NEC does not use the word 'area' in either 210.8(A)(6) or 210.8(B)(2).

    I am not sure what you may be trying to say...


    The requirements in 210.8(A) & (B) in regards to kitchen locations would not need to use the word 'area'. The word 'area' is part of the definition of kitchen and would be redundant.


    Example:
    Take a large house where there is a big room (we see this in vacation houses with large open floor plans). A kitchen is installed in an area of the big room. The whole room is not the kitchen, the area of the kitchen is the kitchen. How is that area to be determined? By the AHJ of course.

    Thank you all for your replies, that is what i was expecting. It is up to the ahj afterall. We are currently wiring a hospital kitchen wich is approximately 100x100. A few countertops have sinks but quite a few adjacent to those don't.

    The counter tops have no bearing on it, all the 125 volt 15 and 20 amp receptacles in a comercial kitchen must be GFCI protected.

    I am saying the word area has nothing to do with sections 210.8(A)(6) or 210.8(B)(2).
