Just looked at the link to manual switches.....sure wish I would have used a gen ready main panel on the house I am building RIGHT NOW! Too far into it to change now. I powered some apartments I used to own with cords by changing from unit to unit during an ice storm a few years ago, not easy but saved all the pipes. The renters thought I was just being nice to keep them warm so it was a little good will along the way. The problem with generators and power outages is that most people do not understand the electricity part well enough to keep someone from getting hurt. Preaching to the choir here I know....
