Thanks guys. I reminded my friend not to go into a store and ask for an
AWG 11 cord. haha
And I also reminded him to use the surge/startup amperage listed on some
appliances rather than just the steady-state load. Finally, I pointed out
that he wouldn't have to worry about this if he had an electrician connect
his generator to his panel...he said he is too cheap, we'll see how he
feels about buying all of those extension cords!
