Abstract
An automatic transfer switch to automatically electrically connect an electrical panel to a second power source, e.g., an electric generator, during interruption or failure of a first power source, e.g., a utility power supply, includes a powered interlock arrangement that is operative to prevent the electrical panel from being electrically connected to both power sources simultaneously.
