Abstract

An automatic transfer switch apparatus for use with a stand-alone generator, for supplying emergency power to a residence or small business.

The automatic transfer switch apparatus is configured to sense a utility line failure, start up and stabilize the generator, and switch over the household circuits from the utility to the generator, and switch back when the utility recovers. A load-shedding feature is provided for shedding and restoring different circuits within the residence, that represent loads of different priority, with loads being shed and restored, according to their priority.
