Abstract
An electrical power transfer system for selectively connecting a load to a first power source or a second power source includes a first switch having an input selectively connected to the first power source and an output connected to the load. A second switch includes an input and an output connected to the load. An isolation device has its input connected to the second power source and its output connected to the input of the second switch to provide a continuous neutral path for the second power source and to isolate a neutral current path of the load from the second power source.
