I know the code requires 2 dedicated 20 amp circuits for kitchen counter recepts. Is there any reference in the nec as to how many plugs can be protected down stream of a gfi recept? This kitchen has 15 recepts, and I am bringing in 3 circuits and 3 gfi's. That is 4 recepts protected by each gfi. I know this is probably a stupid question, but i dont do alot of new homes, and it seems to me i have heard some rule that applies to this. Any response would be much appreciated. Thanx John
Whatever rule you may have heard falls under the heading of "Rumors & Propaganda." There is no requirement in the NEC that limits the number of downstream receptacles on a GFI & there is no UL listing requirement that I could find that limits the number.
Few things are harder to put up with than the annoyance of a good example.
use my "real" kitchen appliances...... espresso coffee maker is 1250w the blender is 450w can opener is 180w coffee-maker, drip/brew cycles 1500w convection oven 1600w crockpot is 70w countertop microwave is 1000w food processor is 480w frying pan 1200w hot plate 1250w portable mixer is 125w popcorn popper 660w toaster is 1000w toaster oven is 1500w waffle iron is 800w clothes iron is 1100w [which i usually do in the kitchen] radio is 100w television is 150w
take the worst case of one dumb blonde [male of course], 50 coffee addicted relatives staying over for breakfast the day after thanksgiving, 4 duplex recepacles on one countertop s.a.b.c....... 1600+1500+1500+1250+1250+1200+1100+1000= !@#$%^&* 10,400w / 125v = 83.2amps...... so you should probably wire the kitchen somewhere around 3 or 4 awg cu
The NEC minimum requirement for a standard dwelling kitchen is two 120 V 20 A small appliance circuits. These two 20 A circuits can catch all the counter receptacles, the gas range outlet, the refrigerator (varify manufacturer's electrical requirements), clock outlet, wall outlets, breakfast nook outlets, dining room outlets and pantry outlets. See 210.52(B) and especially the Exhibit 210.25 in the NEC Handbook.
This is what can be done. . .may take a little getting used to for the cook(s). What you are proposing sounds like a more robust assembly.
I am absolutely sure that I have read on that little sheet of paper that comes in the GFCI box that there should be no more than 6 other outlets after the GFCI. But I don't know who's GFCI's or how long ago I read this.
