15A outlets on 20A circuits
Last week, I posted about running 12/2 wire for a kitchen reno. Well
all the circuits are run. I decided on running all 12/2 instead of 12/3 and splitting circuits. Looking ahead to outlets, had a question. I think I know the answer, but just wanted to confirm. I ran 4 new circuits for the fridge, microwave/range hood, and counter outlets. Am I allowed to use regular 15A outlets? For the counter outlets, I am using regular 15A Decora and GFI's, and for the fridge, microwave just wanted to use regular outlets, like the kind you can get a 10Pk for like $5 at Lowes. |

Why the big distinction between single versus multiple outlets? |

(B) Receptacles. (1) Single Receptacle on an Individual Branch Circuit. A single receptacle installed on an individual branch circuit shall have an ampere rating not less than that of the branch circuit." Since 20amps is greater than 15amps, the 20 amp receptacle may be used on a circuit where it is the only receptacle. |

If it trips, the fridge goes dead and the food spoils. |

All but one of the exceptions disappeared in the 2008 NEC. (The remaining one is for alarm panels.) The NEC panel does not see a problem with refrigeration on GFCI. In commercial kitchens plug-in refrigeration (15/20A, 120V) is required to be on GFCIs. The UL allowed leakage is around 0.5mA if I remember right. -- bud-- |

None of my garage outlets have any GFCIs The original wiring from the 1920's or 30's was constantly shorting out, especially those hanging light sockets hung by cotton covered wires which were half bare from age.

The wiring was a combination of knob and tube, some sort of cloth covered romex, metal sheathed cable, and a small section of conduit, which was actually black gas pipe. The fuse box was supposed to have two 15A plug fuses, but both were 30A fuses, with one cartridge fuse for a main fuses also being 30A, and a pull down shut off handle with both sides of the line switched (hot and neutral) and exposed so anyone could touch it. No one ever died from it. So why the hell do I need GFCIs now? As fas as this old wiring, about ten years ago the garage roof collapsed from snow, and caused the wiring to completely short out when the wires got torn apart as the roof fell. Those old hanging lights got crushed, and the fuse box was mangled. Well, I had to build a new roof, and in the process, I replaced 3 of the 4 walls due to rot and cracked studs from the roof collapse. I ended up having to replace the fuse box with a new breaker box having 12 breakers instead of two fuses. Then I had to rewire with modern romex and new light fixtures and outlets. Of course all of the old wiring was grandfathered in, because this was an old garage from the 1920's, it just had a new roof, and 3 new walls, so I was not required to follow any electrical codes on an 80 year old garage building like this. I even put that old turn type bakelite switch back on the wall just for memories, even though it's not connected. By the way, a year later I built an addition on to the garage and destroyed all but 8 feet of the studs of that original wall. So, it's now a completely new building. except for about 6 or 7 2x4's. But hey, this is an 80 year old building, so I dont need no stinking GFCI outlets or other useless modern nonsense. Hell, if the inspectors were to come, I'll just hammer out the dents on that old fuse box, and screw it to a piece of plywood, and put that plywood over the top of my breaker box. This is an 80 year old building (or actually 90 now), and they did not have breakers or GFCIs in 1920. Unfortunately, your conclusion that "no one ever died from it" is completely incorrect. Not only have people died from it, but buildings have burned down from it. This is exactly why the National Electrical Code has evolved, and every three years has an upgrade. Whether you agree with it or not, the intent of the NFPA and it's NEC is to safeguard life and property. |

I find interesting the statment that: "Of course all of the old wiring was grandfathered in, because this was an old garage from the 1920's, it just had a new roof, and 3 new walls, so I was not required to follow any electrical codes on an 80 year old garage building like this." Say what? The roof collapsed causing lights, wiring, even the fuse box to be damaged to the point they had to be replaced and you were not required to follow any codes because it was grandfathered? Where do you live? Every place I'm aware of you would be required to not only follow code, but bring the part that is being replaced up to the current code. And if, as you claim, you were not required to follow code, then why the need for this statement: "Hell, if the inspectors were to come, I'll just hammer out the dents on that old fuse box, and screw it to a piece of plywood, and put that plywood over the top of my breaker box. " Your approach to safety seems to be that since nothing bad has happened so far, that means you should just keep doing the same thing and not learn from standards and practices that are in place based on the experience from millions of similar situations over decades. Kind of like texting while driving and since you haven't had a wreck or killed anyone so far, it must be OK to keep doing it. |

I believe he was saying nobody had ever died from HIS terribly dangerous and inadequate garage wiring. However, the fact that he allowed the garage to collapse before repairing the water leaks and rewiring the garage doesn't say an awfull lot for his analytic capacity or his maintenance regimen!!!! |

For example, they even put a green ground screw on switches now. WHY? If the switch is in a metal box, it's grounded by the screws, but even in a plastic box, that small piece of metal on the front of the switch is covered by a plastic plate. Those old bakelite rotary swithces with the exposed HOT WIRE screws WERE dangerous, VERY dangerous. I would not even think of allowing such a thing. Not only can children touch them, but when I walk into a dark room fiddling around for the switch, I could easily touch them. In fact when I had that switch in my garage, I planned to replace it, but when I moved onto this property there were a million projects and all had priorities. Yet, I did apply some electrical tape over those screws shortly after moving here. Old wiring was extremely dangerous. Much did not even make common sense, such as any exposed HOT electricity. Those old knife switches were insane on 120V AC. They were fine for a 6 or 12 V battery circuit, but allowing them, or even using them on 120V AC was just stupid. Yes, people were electricuted and some died, and fires started. Then in the 1950's and 60's, all wiring was in metal. Conduit, BX, metal boxes, etc. That was likely the safest wiring ever made. Now we have plastic coated cable in plastic boxes. Plastic burns. It's not as safe, but we rely on breakers rather than plug fuses which could often be oversized. Yet, nothing stops someone from hooking that #14 wire to a 30A breaker if they know how. It's just that back when fuses were used, ANYONE could change a fuse, now it involves the use of tools and some guys wont open any electrical box. In some ways, wiring has improved, in others, it's gone backwards. I still believe that the old metal enclosed wiring was superior to what is used today. But much of that old metal enclosed wiring was connected to fuses, so we have advanced in the regard of breakers. I do have GFCIs on all my outdoor outlets, but not those in my garage, basement, or bathroom. But those are all existing installations and have not been rewired except for a few outlets that were replaced due to wearing out or just wanting a grounded one to avoid hunting down those damn adaptors all the time. Ground screws come on switches because there are a variety of ways to ground equipment, and some methods do require a ground screw. FYI in the 50's and 60's all wiring wasn't in metal. As early as the 20's wiring was available with or without a metal jacket, just as it is today. The conductor insulation has and continues to be improved as better materials become available. |

Before the grounded switches, they only allowed plastic screws on switch plates but that rule was not followed much either. Far as I know, a switch doesn't need to be "self grounding". The NEC just requires metal screws and a grounded metal box. (Receptacles that use the mounting screws must be "self grounding".) If I remember right, the argument was that you might have a plastic plate now, but someone could install a metal plate in the future. -- bud-- |

15A outlets on 20A circuits
wrote outlets, I am using regular 15A Decora and GFI's, and for the fridge, microwave just wanted to use regular outlets, like the kind you can get a 10Pk for like $5 at Lowes. 15 amp outlets are fine. The refrigerator doesn't need to be GFCI protected, but all the counter outlets do. A 15 amp GFCI outlet has a 20 amp feed through He is NOT using a GFCI on the fridge. Read it again. NEVER use a GFCI on a fridge or freezer. I read it too fast too. Ooops. |
