Crossover switch? Cutoff switch?
What's the switch called that you use to cut a circuit over from street
'lectricity to a generator? And do they come in a little 15- or 20-amp version? I just lost most of today's opportunity to work to a power outage (big windstorm today), and spent my down-time buying a generator. I can just toss an extension cord through the window of my office to the generator, but it'd be nice to connect it to my office plugs instead. -- www.wescottdesign.com |

Not something I recommend to anyone these days in most cases. Look for an interlock kit to match your electrical panel. Interlock kits are available for most panels now, in many cases OEM interlock kits, and they are less expensive and more versatile than a traditional transfer switch. I use a Square D interlock kit on my 200A QO panel with a 30A generator feed breaker. It works very well and the OEM interlock kit was ~$60. |

They can spew that nonsense, but that's all it is. It is physically impossible for your little generator to "fry a lineman" unless that lineman violates his safety procedures. They *must* test and ground every circuit conductor before they are allowed to handle it without insulating gloves, so it is simply not possible for them to be harmed by your generator unless *they are at fault*. |

Correction to the end of that last statement: "so it is simply not possible for them to be harmed by your generator unless *both they and you are at fault*." People are still liable for their actions, so charging a dead power line with their generator is strongly recommended against. -- I started out with nothing and I still have most of it left! --anon |

I do the same thing. (Ducks head as people scream at me.) And if I didn't turn off the mains power wouldn't my generator be trying to power up the entire neighborhood? What I'd really like is a little light to come on and tell me when mains power is back on. George H. |

Spend $60 on an interlock kit for your panel and $30 on an inlet box, or spend only a little less to rework those circuits to feed single receptacle boxes next to the panel and put plugs on the circuit conductors so you can unplug them from the panel feed and plug them into an extension cord from the generator. Don't forget to factor in the cost of the extension cords. Basically, doing it half-ass will cost about $75 and doing it right will cost about $100 and give you the flexibility to power whatever circuits are needed at the time. |

I can just toss an extension cord through the window of my office to the generator, but it'd be nice to connect it to my office plugs instead. Smallest I've seen for code-compliant installation in the US is 60 amps: http://www.homedepot.com/p/Reliance-Controls-60-Amp-Utility-Generator-Transfer-Switch-TCA0606D/202216483 We installed one of these and a separate sub-panel to feed the essential circuits (computers, furnace, stove, refrigerator, freezer, etc.) for about $140 and worth every penny. Prior to that we had a 50A range plug on the generator and a range plug fed from a 2-pole breaker in the main panel and a range cord feeding the sub-panel. Manually changing over was not a problem but the transfer switch makes it a 1/2 second task even in the dark. Carla If electricity comes from electrons, does morality come from morons? |
