Generator wiring options
I am picking up a 5000w cont. / 6500w surge generator which should be
more than enough for my needs. I want to keep the refrigerator, 240v water pump, the oil boiler circualtors, and a few lights at at time running. Practically the whole house has the CF lights so my lighting is about 1/4 normal. My max surge is 4000w and running is 2400w. My home's 100A power panel is spread out pretty well where each room has its own 15A breaker which makes my transfer switch wiring a problem. Most of the switches seem to come with one 240 breaker (for my well) and 4 - 15A circuits (1 for Kitchen for fridge and 1 for heating). This leaves 2 rooms for lighting which is the most miniscule part of my needs. Rather than wiring up individual circuits is it possible to get a transfer switch that transfers the entire power to the generator line? |

My max surge is 4000w and running is 2400w. 4000w surge? Do you have a special no-surge pump? [and don't forget the defrost cycle on your frig and freezer] I don't have a pump and kicked off my 5500w generator last winter. [daddy forgot and used the microwave] But it did run the frig, freezer, a bunch of lights & the furnace.

Here are some 8, 10, & 12 Gen-tran transfer switches- http://www.apelectric.com/Manual-Tra...ches-s/128.htm Rather than wiring up individual circuits is it possible to get a transfer switch that transfers the entire power to the generator line? I imagine-- BTW- If you're hiring an electrician for this you might want to ask him about putting a 150 or 200amp service panel in. Probably not a lot more when he's right there. My insurance company was trying to get me to upgrade my 150 a few years back. Jim |

Years ago, I studied the various catalogs, and did some
division on their numbers. I came up with a galon of gas provides 4,000 watts for one hour. Think that's what I ended up. As such, plan to feed your generator a galon an hour. -- Christopher A.

Rather than wiring up individual circuits is it possible to get a transfer switch that transfers the entire power to the generator line? Short answer - make your own transfer switch: Add a dual 30Amp breaker to the panel. Feed the generator to this breaker via a 240 volt male outlet (inlet?). This special breaker should be OFF when power is being supplied by the mains. To enable the generator, turn OFF the main breaker, turn ON this special breaker, connect the generator. In sum, when the power goes out: * Connect the generator * Flip two switches (main to OFF, special to ON) * Start generator When the power resumes: * Flip special to OFF, main to ON * Disconnect generator You're good to go. |

Why should the power company (funded by its customers) pay to install equipment to protect from someone who simply doesn't care and just wants to do it their way? In this particular case what equipment would they install and where would they install it to protect against someone clueless enough to defy all common sense and standard practice? |

In fact, I would say what you proposed he do is far worse than Van Chocstraw's suggestion to backfeed via a generator suicide cord plugged into the dryer outlet. While both are illegal and code violations, at least Van's is a clearly temporary settup. Your proposing that he add a breaker and 240V male outlet to the main panel as a permanent addition. For starters, I've never seen such a male outlet and it seems for good reason. Does such a thing really exist? And now you have a permanent installation in total violation of the law, code, etc. Suppose the installer drops dead one day? Who knows what others in the family, future buyers etc will or won't do? Or how about one day the guy decides to have his kitchen remodeled and the contractor does the right thing and pulls permits. What do you think the electrical inspector is going to say when he sees your contraption? |

I was helping a freind of mine do some wiring in his
trailer. We were about to cut a branch circuit in the bedroom. I suggested turning off the power. He thought he had.

"Van Chocstraw" wrote in message ... That's about a 30 amp generator. You can feed it into the panel via the dryer outlet and it will take care of all your stuff, except electric hot water heater and electric oven. Just kill the main breaker before you connect it. Yes, this is illegal but it works like a charm without a $300 transfer switch. |

If the two chaps you chronicled are not snappy enough to actually TEST for voltage before they lay hands on the wire, they are, perhaps, candidates for a lineman's job that so many worry about. As for the odd person knowing which circuit breaker is which, they're labeled. And not with some strange acronym like "WH" that stands for "Heat Tape." That said, and as you so ably point out, absolute reliance on a properly-labeled circuit breaker is also a source of disaster. |

Do you really have no disregard for human life? My guess is that you are a bored housewife who posts lots of nonsense looking for attention... |

I want to keep the refrigerator, 240v water pump, the oil boiler circualtors, and a few lights at at time running. Practically the whole house has the CF lights so my lighting is about 1/4 normal. My max surge is 4000w and running is 2400w. My home's 100A power panel is spread out pretty well where each room has its own 15A breaker which makes my transfer switch wiring a problem. Most of the switches seem to come with one 240 breaker (for my well) and 4 - 15A circuits (1 for Kitchen for fridge and 1 for heating). This leaves 2 rooms for lighting which is the most miniscule part of my needs. Rather than wiring up individual circuits is it possible to get a transfer switch that transfers the entire power to the generator line? Short answer - make your own transfer switch: Add a dual 30Amp breaker to the panel. Feed the generator to this breaker via a 240 volt male outlet (inlet?). This special breaker should be OFF when power is being supplied by the mains. To enable the generator, turn OFF the main breaker, turn ON this special breaker, connect the generator. In sum, when the power goes out: * Connect the generator * Flip two switches (main to OFF, special to ON) * Start generator When the power resumes: * Flip special to OFF, main to ON * Disconnect generator You're good to go. Or not, what you described is not a transfer switch. A transfer switch is interlocked to strictly connect supply 1 or supply 2 but never both. Ah, right. Thanks for the correction. What I propose is power transfered by a switch, not a transfer switch. I apologize for the confusion. What you described doesn't accomplish any of that and assumes you will be the only one using it, will live forever and never be tired or in ill health or will even never drink that extra glass of bourbon. Correct. And your point is?- Hide quoted text - - Show quoted text - I think what he's suggesting is that what you are proposing is illegal and for the small amount of money involved, it's not worth it. In fact, I would say what you proposed he do is far worse than Van Chocstraw's suggestion to backfeed via a generator suicide cord plugged into the dryer outlet. Yes and aside from legality and even if there were no requirements it is just completely wrong to cobble together a potentially lethal nonstandard installation. Both you an Trader are mistaken. The construct I suggested is legal (with one minor modification). The "minor modification" is the installation to the above of a "generator interlock." Here's a PDF on how a generator interlock is configured (some study required): http://www.interlockkit.com/InstrK5410QOVertNewDsn.pdf Here's a picture of what a typical installation looks like http://www.interlockkit.com/typicalinstall1.htm And here's an exterior generator access plug http://www.grainger.com/Grainger/items/4XT17 I would say it isn't me who is mistaken. Backpedaling won't change that or give you ant credability. You stated this in this very thread when that very interlock kit was suggested: "Yep. $150 for a 6x6 inch bit of sheet metal with a couple of holes. My view is: If the power company wants their linemen protected from backfeed, they should provide the interlocks. " |

Linemen work 16 - 18 hurs for many days when storms strike, often in
nasty weather. give them a break and do the job RIGHT, its not that expensive and a positive at home resale time |

Question:
Let's say a person tries to backfeed a generator into a home (without the proper xfer switch) that has *not* been isolated from the grid by tripping the Main breaker of the home. The generator is now feeding back into the grid to all the rest of the homes on the grid and trying to power all of their electrical loads. What happens to that 5 or 6 kW generator? How soon will it happen? -- I filter all messages from google groups. |

Most brands: Under 1/10 second.
Federal Pacific Electric: Well over 5 years before it trips. With no breaker, my WAG is that either a secondary wire on the generator overheats and burns out, or the motor slows to stall point. Either of those in two to ten seconds. Easily enough time to kill a pole worker. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Caesar Romano" wrote in message ...

Easily enough time to kill a pole worker. a) it'll be out of phase and very unlikely at all to not stall it immediately; the overload is later b) it was postulated the line was _already_ live; the gen-set in this case wouldn't be the culprit (altho still both illegal and stupid trick to pull). Back-feed to distribution system is a serious problem when the line is _supposed_to_be_ disconnected (and has been by the utility or known damage) so the presence of voltage is unexpected. If they know they're working on stuff live then they won't work as if they were working on a (known) disconnected line. Where it's really a problem (and got one of our local co-op linemen a few years ago) is a situation such as a disconnected line, actually confirm it was isolated and talk to the farmstead owner who subsequently got impatient and hooked up the gen-set while they were still working w/o notifying them... Moral of story as homeowner is--don't be an ass or dumb****... -- |
