GFIC breakers
My house was built in 1983 and, therefore, has GFIC circuit breakers only
for the garage and outside outlets. I would like to have GFIC protection on my kitchen outlets as well. Can I just buy a 15 A GFIC breaker and replace the old (non GFIC) breaker in the main panel? Thanks -- Walter The Happy Iconoclast www.rationality.net |

Glad you mentioned the fridge. Thanks.
Maybe I should just put GFIC outlets in the kitchen, instead of using a GFIC breaker. -- Walter The Happy Iconoclast www.rationality.net "xrongor" wrote in message ...

By the way, when you go to the hardware store to get them, it'll work better if you ask for them by the right name: GFCI (not GFIC). Stands for Ground Fault Circuit Interrupter. Sometimes referred to as GFI (Ground Fault Interrupter) - same thing. -- Regards, Doug Miller (alphageek at milmac dot com) Nobody ever left footprints in the sands of time by sitting on his butt.

Maybe I should just put GFIC outlets in the kitchen, instead of using a GFIC breaker. GFCI breakers are expensive, full size (at least for my brand) and a general PITA. Unless you have a good reason not to use a GFCI outlet instead, they are the best choice. You know that you only need one GFCI outlet per cicuit, don't you? Make it the first outlet on the circuit and those after it are protected. I think it was code back in 1983 that kitchens needed two circuits, and the refrigerator had to be on a third circuit. (Mine was done that way, also 1983, and they didn't do anything better than the bare minimum.) You might want to check if yours was done that way before installing anything. |

this thread got me checking my kitchen wiring. everything else around here
was done with one buttock and it's no surprise that this was too. there are 2 20A circuits used for outlets in the kitchen. I'm guessing that originally neither was GFCI protected. Well the previous owners must have decided at some point to add GFCI protection and probably just replaced an ordinary outlet with a GFCI outlet in each circuit. I'm further guessing that the repeated tripping caused by the refrigerator rapidly caused one of the outlets to break. The one on that circuit is broken now. It functions as an outlet but it doesn't provide GFCI protection (it fails the test button) and the circuit as a whole shows an open neutral. The wiring on the outlets looks sound, as best as i can tell given push in terminals, and the wiring at the panel is solid, so I'm guess that that indication is caused by the faulty GFCI outlet. Of course this outlet is within 6 feet of the sink and so it's gonna have to be protected... which means flipping it over to the other circuit... which means fishing cable.... sigh.... at least i caught this before we put up all the new cabinets. |

Question: How can I tell which one is the *first* outlet on a circuit? The first outlet is usually the one nearest the breaker box; but not always. You can tell the last outlet; it only has one cable going to it. And again, you can usually figure out which is first by finding out which is last. You test your theory by disconnecting one wire from the outlet you think is the first one. That will cut power to 1) the outlet in question, 2) All outlets but the one you working on, 3) All outlets, or 4) some outlets but not all. I won't explain this; if you can't figure it out yourself, you shouldn't be doing it! If it isn't the first outlet, then you just have to try another. (Naturally you have to have the breaker off any time you might encounter a live wire...) I am making the assumption that the circuit has only outlets on it; but that should be true for a properly wired kitchen. |

thinking about this further.
Does current code call for 2 GFCI protected outlet circuits and an additional one for a refrigerator? If that's the case I need to have a new 20A circuit run for the fridge. |

Hi Doug
I have followed your advice and invested in the Home Depot "Electricity 1-2-3" book and also the "Complete Wiring" by Stanley Tools. A new challenge! Thank you for your concern.

CAREFUL! First outlet has minimum 2 hot and 2 neutrals. Disconnecting the
wrong one and the outlet still has power. Assume everything has power until you "prove" otherwise. "toller" wrote in message ... You know that you only need one GFCI outlet per circuit, don't you?

Refrigerator must be on its own circuit AND must not be
GFCIed. Obviously if the GFCI tripped, and was reset later, then the refrigerator has lots of unrefrigerated food that a human might not know about. Same applies to a circuit used by both refrigerator and other appliances. Another appliance tripping the circuit could leave a refrigerator getting warm. Again, a human safety issue solved by putting the refrigerator on its own and not GFCIed circuit. wrote: thinking about this further.

Current setup has 2 20A appliance circuits running into the kitchen.
plus (but not really applicable to this problem) 15A lighting 240V/40A oven 20A dishwasher/disposal The problem I've got is that the circuit feeding the outlet for the refrigerator also serves an outlet 6 ft from a sink. So I have 2 choices as I see it. 1) switch the outlet near the sink to the other 20A circuit. Provided the prev owners installed the new GFCI outlet as the first on in the stream that circuit would then be GFCI protected and all outlets near the sink would be on it. I'm gonna double check the install of that GFCI outlet to ensure it's first. The other circuit would then not be GFCI protected and all should be fine to have the fridge running on it. 2) add a 20A circuit dedicated for the refrigerator and GFCI protect both of the original 20A appliance circuits. Assuming that the GFCI outlet that broke is first in the stream I'd just have to replace that. (1) would certainly be easier but that would result in a single circuit w/coffee pot, toaster, new fangled wall oven, and then incidental appliances all on a single 20A circuit. I'm not sure what my toaster wattage is offhand but that circuit looks overloaded to me. Further it puts an outlet that is 6 ft. 6in from the sink on the unprotected circuit. There's more to this than just meeting the letter of the code. I'd really rather have that outlet on a GFCI protected circuit. So it really look like putting in a dedicated circuit for the fridge is the way to go. I've run circuits before in other houses but this one's gonna be a bear. Panel is as far from the kitchen as it could be. Truss roofing with a tiny dangerous attic space full of unfaced insulation with roofing nails sticking out of sheating a couple inches above your head. Electrician coming tomorrow to give me an estimate. Sometimes just cause you can do something doesn't always mean it's the best idea for you to do it. A'int owning a home grand! (yes it is ) ml |

the circuit stays intact upstream of the GFCI device even when it trips. thanks for the heads up ml |

It's all becoming clear to me now. There are actually a pair of breakers in
these devices. One on the line and one on the load side. Both trip when the device trips but how you wire it gives you the option of just removing the device or additionally all of the downstream devices. So lets say I wanted to keep the fridge outlet unprotected but wanted everything else on the circuit protected. It seems to me the answer is to simply wire the fridge outlet as first in stream with an ordinary device and then make the 2nd outlet in the stream a GFCI wired to remove itself and all downstream outlets when it trips, i.e. using the load terminals to continue the downstream circuit rather than using the pigtail method you described. One question though. It's not immediately obvious how the GFCI device sensor is isolated from the current surges when the fridge compressor comes on. Won't this trip the device? True the outlet to the fridge will still supply power and keep your food from rotting but won't you be having to constantly reset the time on coffee makers etc that are on the protected leg of the circuit. thank you for all your help ml |

Ahh reality rears it's ugly head.
Fridge outlet is last in the stream. Hmmm let's see... add a box to splice a new piece of cable to the existing one from the panel so I can make the fridge outlet first in the stream or just make the two outlets GFCI devices wired to just remove themselves...... think that one answers itself.... ml |

Can I just buy a 15 A GFIC breaker and replace the old (non GFIC) breaker in the main panel? The following discussion talks about GFCIs as if they are circuit breakers rated for 15 or 20 amps. But a GFCI does not trip at the rated current, it simply is designed to carry that amount of current. GFCI trip when there is a imbalance of current between the two conductors. This can be caused by you touching one side or the other while standing in a puddle of water. They are very sensitive and I believe the test button just connects a 10K resistor to ground. So, I don't see why any special provisions need to be made for a frige although you may want it to be the only thing on a breaker circuit because of compressor motor start-up transient current draw. |

It would be most unfortunate to wake up in the morning to find your GFI
had tripped the evening before, for whatever reason. It would probably be a lot like the time the start relay on my compressor failed one night, and I woke up the next morning to find a small pond from the melted ice all over my formerly unwarped parquet floor. |

All done.
2 GFCI's outlets followed by a non-GFCI outlet for the fridge. All is working perfectly. Thank you Doug for your accurate advice and putting up w/my questions. You probably saved me in the neighborhood of $500 today. ml |

simple answer, yes. assuming they make one that fits your panel, and they
probably do. that said, you dont want the fridge on that circuit. Why would you not want the fridge on that circuit? In fact as far as that goes if money were not an issue and you did not care what breakers cost why would you not use all GFCI breakers for the entire house? Joe |

My house is only 6 years old so I have these breakers in my kitchen and

Yes, they may save someone in a very bizarre situation. But other than the very bizarre situations that you are concerned about, I'm comfortable using them only where they are most likely needed, and hesitate to put them into applications where they are not. Because as I pointed out they may kill you too which is why its completely against code to put smoke alarms on a circuit protected by a GFI but if you want to wake up to a fridge full of rotten food and ice melted all over the floor or perhaps not be alerted to a fire well then go right ahead and put GFIs wherever you want in fact you could even replace every outlet with a GFI AND replace every breaker with a GFI breaker just to be extra extra safe after all it is America and it is your house well technically I suppose its probably the banks house but go right ahead and do what you want its possible they make GFI switches too and you could also replace all your switches with GFIs and maybe too you could only buy light fixtures with built in GFIs and then this way you are getting like backups to backups to backups to backups and your house will be really really safe and protected against really bizarre situations. Unless of course, the misuse of a GFI kills you. That would be completely different. And - it would be really bizarre. |

Dude I am not trying to argue with you I am just trying to understand the
reasoning. You say code prevents smoke alarms from being on a GFCI circuit. OK. By this reasoning it is more likely that a smoke alarm would be made inoperative from a false trigger when your house is on fire than something actually accruing on that line to trigger the GFCI to shut down and turn off the smoke alarm. By this same reasoning it would be more likely that a GFCI would falsely trigger and shut down the refrigerator causing spoiled food and someone eating it and dieing than the breaker correctly triggering in that circuit and saving someone's life. Granted all of these would be very bizarre situations but if the cost of doing it were not an issue I am having a hard time understanding the reason not just use the a GFCI breaker on every circuit in the house. Do they false trigger that often? They have not for me. Joe "Matt" wrote in message oups.com...

Joe,
It's not an issue of how often they false trigger, or if they ever false trigger at all. If you want to put a GFI on your fridge circuit - go ahead. There used to be a guy here named Tom Horne, and he had every version of the NEC ever released memorized. He could tell you if there are any rules in the NEC that prohibit the use of a GFI on EVERY circuit, specifically on the utility circuits in your kitchen. I think Doug's constant posting of complete crap made Tom lose hope though, I havn't seen him post here in a long time. I can tell you that as *I recall* (from the period I worked full time as an apprentice electrician, regardless of the people who will insist I am a plumber, or am not at all qualified in any way to comment on electricity or electrical related items) in a house your age the smoke alarms *should* have been wired on a dedicated circuit, and they *should* also all have a third conductor which causes all of them to fire if any one of them fires. I say this to you because *if* your smokes are all on one circuit - and *if* (for whatever reason) the GFI you put in that circuit trips - the chances are VERY GOOD that you won't notice it. And in this situation, you have turned a life saving device into a life taking device. |

doing it were not an issue I am having a hard time understanding the reason
not just use the a GFCI breaker on every circuit in the house. Do they false trigger that often? They have not for me. No, they don't false trigger all that often, but they don't safe lives all that often either. In the absence of water or other excacerbating circumstances, it's actually pretty rare for an electrical fault to do anything other than give someone a painful shock. So the point isn't than the negatives of a GFCI are big, it's that, while they're small, the positives aren't necessarily bigger. Even when numbers are really, really small, some of them are bigger than others. |
