I work in a factory that basicly has no GFCI in it my boss has asked me to find out what the code is on were we need to install them. we have outlets on almost every i beam throughout the plant with hard wired extension cords and some of the outlets are running next to water pipe that comes down the i beams. guys i need alittle help on this were all do we need to have GFCI's
210.8(B) Other Than Dwelling Units. All 125-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in (1), (2), and (3) shall have ground-fault circuit-interrupter protection for personnel: (1) Bathrooms (2) Rooftops (3) Kitchens
Per the code the above are the locations where GFCI protected receptacles are required. Of course 527.6 requires that any temporary wiring used for repair or maintenance must have GFCI protection. Extension cords are temporary wiring. So you either use portable GFCIs of install GFCI protected receptacles anywhere maintenance or repair work could be done. Don

i saw both of the sections you guys have listed in my nec book when i was looking today. the temp wiring (extension cords) are used by everyone in the shop so that is what i thought they should be protected. When we say kitchen does that include a break area that has 3 microwaves and a fridge.

As a rule of thumb, GFI's go where ever moisture is likely to be present. Therefore, a breakroom without a sink would probably not "need" them. Also, as a rule of thumb, GFI's might NOT be a good idea if the appliance messes up the power, by either having a motor start up against a load (refrigerator or compressor), or a large transformer (flourescent lights, battery chargers). I'd also think twice about GFI's serving equipment that invariable has some current leakage (dishwashers, garbage disposals). GFI's are very good detectors of damaged extension cords.
