Automatically Operated Transfer Switch is installed where a backup generator is located so that the generator may provide temporary electrical power if the utility source fails. The Transfer Switch not only acts as a safety switch in the backup generator but also commands the backup generator to start. The Transfer Switch continuously monitors on the electric utility feed and it isolates the backup generator from the electric utility when the generator is on providing temporary power. Automatically Operated Transfer Switch is available in different specifications and dimensions to suit the specific requirements.
