The one thing that hasn't been addressed about the backfeeding, is why. I know it's against code, and that's a good enough reason. But, the reason it's against code is, when you do this, you are putting power back into the grid. The electricity from the generator will follow the electric lines right back out to the transformer. This can cause serious problems with the eletrical system in the area. It can even cause your generator to catch fire.
Unless there is a transfer switch on site, or the breaker box has been wired with an interlock on the main to a back-feed breaker, you should never backfeed an eletrical system.
