Emergency Generator Circuit
We own a 5000/6260 Watt generator that is used for temporary emergency
service during electrical outages. In our area (SE Kansas). Outages related to thunderstorms and ice storms are fairly common. Outages can last from a couple of hours to more than a day. Being a lot Irish, I really don't want to spring for the full $600 - $1,000+ plus for a full up transfer switch installation. A am also opposed to the old Dryer Plug approach. Remembering to isolate the house with main breakers might work now; but as our brains age it looks like a good way to kill a lineman. Here are needs and a proposed approach: Main Needs a 1) Sump Pump main control circuit (basement) 2) Backup Sump Pump battery charger circuit (basement) 3) Furnace (central heat NOT air conditioning - basement) 4) Freezer (basement) 5) Refrigerator (main floor) These five items are well within normal and surge capacity of the generator so I should have some capacity to run a few lamps. Planned Approach: 1) Install a standard four prong female generator connection box so that 10/4 wire passes directly through the sill plate of the house. This will be done outside, or just inside of the garage door. (In either case the generator will, of course, be located well away from the house). 2) The 10/4 wire, from the box, will enter the basement and be routed down to about four feet above the floor via conduit. 3) At the bottom of the wire/conduit I will install a fourplex box and split the circuit into two 120v circuits with a standard two-plug receptacle on each. This will serve items 1) through 4) above via direct connection or extension cords. The longest cord run will be 15-20' This circuit will be "dumb" and will not be hooked to the main house circuit. When needed, we will move the generator outside of the garage and use a standard 4-blade, 30 amp, 30' generator cord to connect the generator to the dumb circuit which will serve basement needs. The fridge and lights will be served by a couple of the four standard 120v circuits on the generator. Anyone else done something similar - or better? I do want to keep cost down and keep it safe. But it is a solution that MIGHT get used once every year or so. Thanks RonB |

Always a pia to have to drag cords out, especially if it turns out to be a short outage. If you have a garden variety circuit breaker panel, you can probably install an interlock kit, which cost around $150. Personally, I'm pretty cheap, so I built my own. Cost about a buck. Here's a link to the interlock kit: http://www.interlockkit.com/?gclid=C...FYg65QodWSKgCA |

Thanks RonB Cheapest way I know of for a safe system is to use Kirk locks. place them on the main breaker and the breaker used to connect the generator. The locks allow only one of the breakers to be ON at a time. Jimmie |

It's a complete kit, and only takes a few hours to install: http://www.amazon.com/Reliance-Contr...3587946&sr=1-1 |

Thanks RonB I made some long extention cords out of 12/3 wire. I put male plugs at the generator end, where they plug into the generator outlets. They end up in outlet boxes located so that I can unplug the refrigerator and freezer from the wall outlet and plug them into the generator outlet. I have plugs attached to the lines to the water pump, furnace, etc., and just switch from house to generator when needed. Not elegant but it's cheap and it works. |

But it is a solution that MIGHT get used once every year or so. Thanks RonB Whatever you decide, spend some quality time with the local electrical inspector. You might find that an extension cord "bolted to the structure" is no longer an extension cord. Even stuff that's not permanently energized might be under the jurisdiction of the local authorities. "Safe" and "Legal" may not be equivalent. YMMV The disturbing part was that the inspector said he'd approve stuff that appeared to be specifically prohibited by the NEC. Depending on with whom I talked, if I messed with the breaker box, I may or may not have to bring the whole primary side up to current code. That's PROHIBITIVELY EXPENSIVE. Last thing you want is for your fire insurance provider to find a loophole. Better to have the inspection sticker. I found a great deal on a generator at a garage sale. Found another great deal on a Reliance DIY transfer switch. No doubt in my mind that I could make a safe and reliable installation. By the time I talked with the local electrical inspector and found out that the permit and inspection fees cost more than the generator, I scrapped the project. Easier to put a doggie door in the wall and poke the extension cord thru when needed. No muss, no fuss. |

What an interlock switch does is guarantee that when the MAIN is ON, these two new breakers must be OFF. When the two new breakers are ON, the MAIN must be OFF. All this is done to prevent your generator from backfeeding the distribution system and presenting a safety hazard to the linemen. You may dispense with the interlock switch is you're careful. Your cost for this set-up is maybe $20 each for the breakers and $40 for the male plug. |

YOU GUYS DISCUSD THINGS LIKE EVERYONE HAS PURCHSING POWER AND ACCESS
TO A HOME DEPOT OR ELECTRICAL SUPPLY STORE. WHAT IF ..... THE WORLD SHUT DOWN ..... NO ACCESS TO ANYWHERE LIKE THAT... COULD YOU BUILD THE GENERATOR AND SUPPLY YOUR PREMISES WITH WHAT YOU HAVE TO PROVIDE ADEQUATE POWER, TO YOUR COMPONENTS & SURVIVE THE WORLD? ARE YOU PREPARED TO SURVIVE, OR WILL YOU HAVE TO GO SHOPPING FOR ELEMENTS? JUST A THOUGHT PAT ECUM |

Maybe put a piece of PVC with a threaded cap on it through the band joist above the sill, so I have a ready-made hole to pass the extension cord through. -- aem sends... |

Nice thing about the Kirk locks is he would only need to install a 50amp 240 vac breaker for the generator the rest of the mod is just fastening the Kirk locks to the panel. On a residential panel room for the locks will be limited and the generator breaker will have to be mounted at the bottom of the breaker column . Jimmie |

I am working on this problem also. Generator will be propane fueled. Remote
switch for starting..Will add outlets near freezer, refrigerator and heat system. These will only be connected to the generator. Safe and easy to move plugs from one outlet to others. You will need a lot of propane, far more than 1 or 2 gas grill 20 pound tanks. buy the smallest generator you can get away with, because big generators use lots of fuel even at idle |

Congrats natural selection hasnt already shortened your life Anyone who has a visual hazard that may cause a traffic accident, and refuses to prune or better remove the offender completely, and threatens violence, needs serious help........ locally the town cites people like you, remove hazard or be fined and ultimately be brought in before the magistrate. one idiot failed to remove the hazard even after several accidents, the town courts finally jailed him for a couple days, and had the road crew remove the hazard, and billed him for the removal. he didnt pay and had his home liened. It drug thru the courts for years, he finally had to pay up at home sale time, rumors said it cost him 10 grand in legal court, lawyers, road crew removal at union wage rates. very expensive when 5 minutes with a chain saw would of saved him 2 days in jail and lost wages. he countersued and lost for lost wages. The town upgraded its line of site laws, the next idiot will be paying a thousand dollar a day fine..So the jerk left his legacy You his brother or uncle? |

An extension cord connects the inlet to your emergency receptacles. 3) At the bottom of the wire/conduit I will install a fourplex box and split the circuit into two 120v circuits with a standard two-plug receptacle on each. This will serve items 1) through 4) above via direct connection or extension cords. The longest cord run will be 15-20' This circuit will be "dumb" and will not be hooked to the main house circuit. When needed, we will move the generator outside of the garage and use a standard 4-blade, 30 amp, 30' generator cord to connect the generator to the dumb circuit which will serve basement needs. The fridge and lights will be served by a couple of the four standard 120v circuits on the generator. If your generator circuit breaker is not 20A you need 20A protection for the basement receptacles. I like the interlock from RBM. You would have to make sure the loads you want are balanced on both legs of the panel. Check the cost and convenience of different methods. -- bud-- |

Planned Approach: 1) Install a standard four prong female generator connection box so that 10/4 wire passes directly through the sill plate of the house. This will be done outside, *or just inside of the garage door. *(In either case the generator will, of course, be located well away from the house). 2) The 10/4 wire, from the box, *will enter the basement and be routed down to about four feet above the floor via conduit. 3) At the bottom of the wire/conduit I will install a fourplex box and split the circuit into two 120v circuits with a standard two-plug receptacle on each. *This will serve items 1) through 4) above via direct connection or extension cords. *The longest cord run will be 15-20' This circuit will be "dumb" and will not be hooked to the main house circuit.

Thanks RonB A transfer kit is easy to install you can do it yourself. I got a complete kit like the one RBM shows mine is a Generac kit from lowes and includes everything. it it safe and has built in amp meters so you can monitor the load. You might get one for 2-300. |

* If a neighbor meddles with something on my house without knowing - or figuring out - what's up, he owns the problem, not me. The neighbor on one side of me is a granny-lady who can't figure out how to open her mailbox. The dude on the other side keeps coming in my yard and trimming my bushes (so he can see traffic when exiting his driveway). I've already told him that if he comes in my yard one more time with the intent to practice malicious mischief in the nighttime by destroying my property, I'm gonna shoot him in his ****in' head ! Congrats natural selection hasnt already shortened your life Anyone who has a visual hazard that may cause a traffic accident, and refuses to prune or better remove the offender completely, and threatens violence, needs serious help........ locally the town cites people like you, remove hazard or be fined and ultimately be brought in before the magistrate. one idiot failed to remove the hazard even after several accidents, the town courts finally jailed him for a couple days, and had the road crew remove the hazard, and billed him for the removal. he didnt pay and had his home liened. It drug thru the courts for years, he finally had to pay up at home sale time, rumors said it cost him 10 grand in legal court, lawyers, road crew removal at union wage rates. very expensive when 5 minutes with a chain saw would of saved him 2 days in jail and lost wages. he countersued and lost for lost wages. The town upgraded its line of site laws, the next idiot will be paying a thousand dollar a day fine..So the jerk left his legacy You his brother or uncle? Points: * Shows what you know. The bushes in question are no more than 2-1/2' high. He chops them to the ground. * I may agree with the point about a visual hazard, but that's not the case here. I also pity those who would live in such a benighted area. In fact I PLANTED the goddamn bushes to keep the neighbors from driving across the 15'-wide grassy strip and using MY driveway to get to the street (the passage in the street's median is in front of my driveway). * I'm not "threatening violence," my state's penal code is. Texas Penal Code 9.42 A person is justified in using deadly force against another to protect land or tangible, moveable property (2) when and to the degree he reasonably believes the deadly force is immediately necessary: (A) to prevent the other's imminent commission of arson, burglary, robbery, aggravated robbery, theft during the nighttime, or criminal mischief during the nighttime, ... * I'm neither his brother nor his uncle. To the best of my knowledge, we are not related (different races, he's an enlightened Yankee (but evidently not sufficiently enlightened), he votes Democratic, etc.). My dad has passed on so I can't ask him how frisky he was some 45 years ago. * He's got a 50' tall cottonwood tree between his house and the street. I've considered chopping it down because each fall my front yard is armpit-deep in leaves and I would think the principle to which he harkens would similarily apply. I haven't done so because of fear that the tree would land in the street and contribute to an INNOCENT person having an accident. |

You need a way to connect the furnace to an extension
cord. One of the better ways is to install an "inlet" (a male plug that mounts like an outlet) at the furnace. **I know you know this, and just mis-typed (double throw switch) An added double pole switch connects the furnace CY: Actually, a double pole double throw switch would be wise. So that the generator neutral doesn't get connected to the house neutral. to either normal wiring or the inlet. An extension cord connects the inlet to your emergency receptacles. CY: Sounds good, cord to the inlet. I like the interlock from RBM. You would have to make sure the loads you want are balanced on both legs of the panel. Check the cost and convenience of different methods. CY: The interlock sounds like a good idea, if the panel supports it. |

The transfer switch having to be single pole or double pole depends completely on the neutral/ground bonding system of the particular generator being used. In either case it needs to be double throw |

It'll work, but it's kind of a Rube. Always a pia to have to drag cords out, especially if it turns out to be a short outage. If you have a garden variety circuit breaker panel, you can probably install an interlock kit, which cost around $150. Personally, I'm pretty cheap, so I built my own. Cost about a buck. Here's a link to the interlock kit:http://www.interlockkit.com/?gclid=C...FYg65QodWSKgCA It is an infrequent enough event that dragging cords is not an issue. I am just trying to control the cord tangle. This approach lets me hit all of the basement items with short runs; and a relatively short run from the generator to the upstairs fridge. Otherwise I would have to run into the house, down a stairway, and then nearly the length of the house to get to the basement. There is a basement window near the basement items but that requires removing a window bubble -- not exactly what I have enjoyed doing during a downpour. Regarding other comments: 1) The next owner is not an immediate concern. This is our retirement house and I don't plan on selling it --- Our Kid's issue :^) 2) Inspection and building standards are not a real issue. I want it safe, but in our rural community there are no inspectors. The electrician who wired our home 2-3 years ago originally lived in KC and is KC code conscious and I was happy with that. Actually, I considered boring a big enough hole in the garage wall, through the sill, to accept a direct routing of a standard generator plug to the basement. The cord would be fed to the basement when needed; and then use an octopus plug from there. The hole would be covered with a simple, sealed cover to keep bugs out. However that requires boring a 3" hole and I am not comfortable with putting that large of a hole in the sill. RonB |
