    More importantly, you need an interlock plate for your fuse panel so that the backfed breaker and the main cannot be on at the same time. There has been a suggested reference recently here.

    You don't want to electocute a lineman, do you? Your generator can electrify the line to 10,000 volts or more with a transformer acting in reverse.

    You also need a generator input connector mounted on the outside of your house.

    Even so, you'll need 4 conductor wire from the generator to the input connector, but you may be able to by the cordset.

    Inside you'll need 3 conductor with ground.

    Alternatively, you can use a transfer switch instead of the interlocking breaker.
