Re: GFI receptacles
Your profile indicates that you are a consultant, and now I better understand the specific meaning in your case of the statement " We missed the ground wiring on the construction document. " If you are using a metal raceway system, or some other metal enclosed wiring method by which the metal enclosure is rated for use as an equipment grounding conductor in accordance with article 250, then I would have to say you could. Since I'm from the Chicago area, that is how most homes and business are wired. One exception would be health care situations, especially within the city of Chicago, where an insulated equipment is required, in section 18-27-517.13 (a), among other places.
