In a manual transfer switch, there is an operator who effects the transfer throwing a switch whereas in an Automatic Transfer Switch(ATS) the sense of one the sources has lost or got power automatically, generally installed were back up generator is available to provide temporary electrical power. To avoid possible injury that might be caused by such sudden start-ups, the system’s automatic start cir-cuit must be disabled before working on or around the generator or transfer switch. † When an automatic transfer switch is installed for a standby generator set, the generator engine may crank and start at any time without warning. The transfer switch is the device that transfers the power from the utilities power to the standby generators power, as shown in Figure 1. Set Up Outlets. Paired with a PowerCommand generator set, the result is a robust power system capable of ensuring reliable performance while maximizing cost effectiveness. If this is a standard circuit breaker, there is no possibility of it having more than one wire of different definitions (any wire directly attached to a circuit breaker terminal is considered "hot").
