100ft
i assume thats as close as you can get and be reasonably level ?
trees or other structures in the way
that far from the house, why not run your generator during the day when it is the hottest period, and more likley to have low voltage power problems
a 20 or 30 amp power outlet, your going to struggle during the day if you need the MW, coffee maker, toaster or any other high draw item, while the A/C is running
you can't run (2) high draw items on a 20 amp home circuit at 100ft of extension cord
