Hooking a generator up to main panel.

I recently purchased a 5500 watt generator. Someone told me that there is an extension cord with 2 female ends that is supposed to allow you to plug into any outlet in your house, and backfeed current back into your panel, to feed other breakers. I was told that you are supposed to turn off the main breaker, and any other large breakers, and just turn on the 15 amp breakers for your light's, sump pump, etc. Does this sound right? I thought you where supposed to install a backfeed box, and wire the circuits into this box that you want to run, and then wire those circuits to the breakers in the main panel. Any advise?

Don't listen to that "someone" about anything electrical. Thats a good way to hurt or kill someone and start fires.

You have the basics correct in the second part or your statement. The "backfeed box" you mention is called a transfer switch.

One of the electrical Pro's will probably be around and can provide references.

Yes you need, must have some sort of transfer switch to interlock the 2 power sources (utility and generator)
You could use one of these, for example, to back feed your panel. Generator InterLock Kit

And then get you one of these

The use of a cord as mentioned to backfeed the panel could have deadly consequences for yourself or a lineman. It is also not a Code approved means to supply generator power during an outage.

Do the correct thing and have a transfer switch installed.
