I am planning to backfeed my main panel through a 220 outlet the I have inin my garage. I know that I have to turn off the main breaker so that I do not feed into the mainfeed, but is there something I need to watch for within my panel? Feeding the panelwith 220 won't hurt the 110 circuits? Had a friend say this could be a problem.What do the rest of you think?

That is how I do it and have never had a problem. First I turn off the main breaker, then I hook the 220 line from the generator to the dryer 220 outlet. Just be careful to remember which end of the line is hot. It should not cause a problem with your 110 circuits as long as you connect the 220 with a ground. If you think of it as a d.c. circuit it would be +110, gnd., -110. It is the same with a.c. except + and - reverse every 1/60 of a second. ....

Tim you propose what a lot of folks do and to a point it is not dangerous. Things to watch out for, if you need 110 you will have to pull a neutral from the generator. Hooking up 220/240 volt to a 2 pole breaker will not give you 110. As the other post mentioned, make sure you ground the generator and connect this same ground to the panel. Last, make sure you turn the main off and all of the other breakers until you start the generator. Bring the breakers back on line one at a time making sure you haven't overloaded the generator.If you plan to leave the generator connected all of the time or want something less temporary, there are a number of different ways to do this. Feel free to contact me if I can help. By the way I am a consulting electrical engineer.Good luck. ....

My father installed a seperate box, for this purpose about 3 months ago.It is very clean & neat, not to mention almost idiot proof. Not that anyone here is an idiot, but everyone can make even the slightest of mistakes or skip a step. electricity doesn't give second chances. IMHO, its worth the few extra bucks to have a small box installed, and hardwire it directly to the panel. Secondly, the wire for your dryer will be supporting the entire load. Shouldn't be a problem unless you have a sizable generator.BTY, I think he spend less than $50-75 for everything. ....
