Has anyone used these small residential transfer switches made by APC (Scheider Electric) for standby portable generators? I saw one at a customers home the other day and they seem good. They can load shed if the draw goes over the generators capacity.

The one thing that I didn't like was there was no exterior control of the individual circuits and the overcurrent protection (fuses) are behind the cover, so the average homeowner can't reset/replace when tripped.

Just looking for comments from others who have used the product?
