ECN Forum Forums Code Related Discussion NEC & other Code issues GFCI recep in industrial settings, need some code help.

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

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.

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.

jlhmaint,
there's really no definition of kitchen, however most may side with a food preperation area......

NFPA Definition of a Kitchen.

An area designated for storage, preparation, cooking, and serving of food for members.

Just my 2 cents but what code book are you following? Here in NJ it is the 1999 NEC.

JLH in our plant we use GFI for all watercoolers, the rest of them are not. We also use them on extension cords.

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.
