Patent ID: 7599171

Claim:
An electrical distribution panel comprising: an enclosure; a first power input; a second power input; a first circuit interrupter including a first terminal electrically connected to said first power input and a second terminal; a first bus electrically connected to the second terminal of said first circuit interrupter; a number of second circuit interrupters powered from said first bus; a second bus; a number of third circuit interrupters powered from said second bus; a transfer switch including a first input electrically connected to said first bus, a second input electrically connected to said second power input, and an output electrically connected to said second bus, said transfer switch being structured to selectively electrically connect one of the first and second inputs of said transfer switch to the output of said transfer switch, wherein said first bus and said number of second circuit interrupters are structured to power only a number of non-critical loads, wherein said second bus and said number of third circuit interrupters are structured to power only a number of critical loads, which are different than said number of non-critical loads, and wherein said second circuit interrupters operate independently from said third circuit interrupters.
