| 1. A loadcenter for a first power source having a first status, a second power source having a second status, a third power
source having a third status, a critical load and a non-critical load, said loadcenter comprising:
a first distribution panel having a first circuit breaker to selectively receive power from the first power source;
a second distribution panel having a second circuit breaker to selectively receive power from the second power source;
a third circuit breaker to selectively supply power from the third power source to the first distribution panel;
a fourth circuit breaker to selectively supply power from the first distribution panel to the non-critical load;
a fifth circuit breaker to selectively supply power from the second distribution panel to the critical load;
a circuit isolator to selectively supply power from the first distribution panel to the second distribution panel; and
a controller structured to monitor at least the second status and the third status, and in response to the third power source
being unacceptable and the second power source being acceptable, being further structured to:
open the third circuit breaker;
open the circuit isolator;
close the first circuit breaker; and
close the second circuit breaker,
wherein the controller, in response to the second power source being unacceptable and the third power source being unacceptable,
is further structured to:
open the third circuit breaker;
open the second circuit breaker;
close the circuit isolator; and
close the first circuit breaker.
