Connection scheme for a 4.375 MVA, 12.47 kV cogeneration generator feeding through existing partial main breaker 73DAB2 in the cogen motor control center room. A feeder circuit routes from 73DAB2 with 3-350 kcmil 15 kV conductors and a number 2/0 ground in a 5-inch conduit to the cogeneration generator. An additional connection feeds panel PNL73DC with two number 4 conductors in a 1-inch conduit. Existing switchgear EM is connected upstream within the partial main breaker assembly.
