wire size for generator run

I am connecting a Generac 7,500 watt generator (model 5943) to my electrical panel through a 30 amp inlet box located in my garage.   The run of wire will be about 125 feet long.  What size wire will I need?  I've read that since the run is over 100 feet I should size down to  8-3 wire.

#8 copper would be the right size for 30 amps at 125 feet.

I would also remind you that your "inlet box" should have recessed male connectors.  Under no circumstances should you use a cord from your generator to the house with male plugs on both ends.  Those are called "suicide cords" for good reason.  You should also install a transfer switch at the panel to disconnect your house wiring from the power company lines when using the generator.  Failure to use a transfer switch could allow the power from your generator to feed back out onto the electrical grid, injuring a nearby worker or damaging your generator.
