Abstract

Disclosed is an automatic electric transfer switch arrangement for connecting an alternate power source, which may be a standby generator to a residential unit in the event of a utility power outage. A control disposed in a sub-panel allows for the pre-selection of high power loads to reduce the total utility demand during peak demand periods. When the utility power is restored, the standby generator is disconnected and the utility power is reconnected. During a power outage, the high power load items that were pre-selected are disconnected from the generator to prevent the system requiring from more capacity than the generators capability. The load shed mode can be automatically activated remotely, via a wireless transceiver. Further disclosed is an ATS system that can monitor the power level at both the utility meter and standby generator due to it unique placement between the utility meter and the house breaker.
