Disconnect the breaker to the outside power lines. Plug your portable generator into the dryer outlet. You can run whatever is the capacity of your generator.

If you want to plan for this. Place a four pin, 220 welding socket and box at your breaker. Assemble the required jumper cable and you are ready for an outage.

If you have any questions or comments on this suggestion, don't do it. Have a local electrician install and give you instructions.
