    Top 2008 Code Changes

    210.8 ─ Ground Fault Circuit Interrupter (GFCI) Protection for Personnel

    By Mike Holt
    Outdoor GFCI protection requirements for 15A and 20A, 125V receptacles at nondwelling unit occupancies were revised as follows:

    (B) Other Than Dwelling Units
    (4) Outdoors in public spaces. All 15A and 20A, 125V receptacles installed outdoors in public spaces ─ for the purpose of this section a public space is defined as any space that is used for use by, or is accessible to the public shall be GFCI-protected.

    The 2005 NEC only required 15A and 20A, 125V receptacles “outdoors in public spaces” to have GFCI protection. This change now requires GFCI protection for these types of receptacles installed at all outdoor locations, except as provided by the exceptions for snow-melting and deicing equipment and industrial establishments.

    The Fluke 1735 Power Logger is the ideal electrician or technician's power meter for conducting energy studies and basic power quality logging. Set the Power Logger up in seconds with the included flexible current probes and color display. The power quality meter measures most electrical power parameters, harmonics, and captures voltage events.

    Code Quiz
    By Steven Owen
    Q. When installing a concealable nonmetallic extension from an existing 15A non-grounding receptacle outlet in an existing dwelling unit, where there is no equipment grounding conductor, is it permissible to install grounding-type receptacles as part of the nonmetallic extension?

    1. Under no condition is a grounding-type receptacle permitted, as there is no equipment grounding conductor or grounding provision in the existing circuit.
    2. Yes, if an AFCI receptacle is installed to protect all receptacle outlets on the branch circuit.
    3. Yes, however, the only method permitted is the use of GFCI receptacles.
    4. Yes, if grounded in accordance with 250.130(C), 406.3(D)(3)(b), or 406.3(D)(3)(c).
