Sheet E-7011: Path 7-01 Landings from the 12.47 kV Boundary to the ATS Normal Terminals

What this sheet shows

E-7011 is the engineering study of path 7-01 from the project MV branch boundary to CB7-01, with each phase drawn and named rather than collapsed to one line. The note at the head of the sheet calls TB-MV7-01 L1/L2/L3 the project MV branch boundary, on a 12.47 kV design basis. Each phase lands on its own TB-MV7-01 terminal, marked MV feeder boundary, and leaves that terminal as Z7-MV-01-L1, Z7-MV-01-L2 or Z7-MV-01-L3 into MVS7-01 and FCO7-01 / LOADBREAK SET. Beyond FCO7-01 the same three phases are Z7-FCO-XFP-01-L1, L2 and L3 into XFP7-01, then Z7-XFP-T-01-L1, L2 and L3 into the primary of T7-01. The transformer block reads 12.47 kV delta / 480Y-277 V, with Dyn1 noted as an OEM GA basis, and the secondary terminals drawn under it are X1, X2 and X3, with X0 taken off separately. X1, X2 and X3 become Z7-T-CB-01-L1, L2 and L3, pass through CB7-01, and continue as Z7-CB-ATS-01-L1, L2 and L3. The title block names that chain in order: FCO, XFP, T7-01, CB7-01.

Project boundary and the package-function label

TB-MV7-01 L1/L2/L3 is printed as the project MV branch boundary. The loadbreak callout on the feeder side of the branch is two lines: MVS7-01, then FCO7-01 / LOADBREAK SET. The conductors that leave FCO7-01 into XFP7-01 are tagged Z7-FCO-XFP-01-L1, L2 and L3. The title block lists FCO first, and that element is the device tagged FCO7-01. XFP7-01 is labeled XFMR PRI LB + FUSES, and the line under that reads transformer package function. The primary loadbreak and the primary fuses carry that package-function label. The head note is the coordination instruction at the feeder-boundary terminals. It calls the landings project interface points, and it says hardware selection and utility demarcation are to be coordinated. That utility demarcation, to be coordinated, is discussed in the electrical architecture notes.

The neutral is two external jumpers

X0 is taken off on its own conductor, clear of the phase lines. It leaves T7-01 and lands on terminal 1, labeled TB-CB7-01-N, neutral landing from xfmr X0, external jumper 1-2. Terminal 2 of that block is labeled TB-CB7-01-N to ATS normal neutral, external jumper 1-2, and the conductor from terminal 2 is Z7-CB-ATS-01-N. Both segments carry the words external jumper, and both are numbered 1-2, so the sheet shows two external landings rather than a neutral drawn inside T7-01. The windings beside that neutral are labeled 12.47 kV delta / 480Y-277 V, and Dyn1 appears under the voltage, qualified as an OEM GA basis. X1, X2 and X3 are the phase terminals of that secondary, each carried on its own conductor to CB7-01.

What is printed study or to be coordinated

CB7-01 is printed once, above the three phase lines Z7-T-CB-01-L1, L2 and L3, and each of those lines is marked 3200 A STUDY. The same study figure is repeated on L1, L2 and L3. Beyond the breaker the phase conductors are Z7-CB-ATS-01-L1, L2 and L3, and each one ends like the neutral: a leader reading to 7021, and the words CB7-01 to ATS7-01 normal, followed by L1, L2, L3 or N. Those leaders are the edge of this sheet. ATS7-01 is not drawn on it. The title block calls the drawing an engineering study, shows No Scale, dates it 2026-09-27, and gives the number K&K DATA-E-7011. With the footer, the issue is Design Development — Public Edition P1, a reference design for study and evaluation. In the sheet's own words: hardware selection and utility demarcation are to be coordinated, the vector group is Dyn1 on an OEM GA basis, and each breaker pole value is printed 3200 A STUDY.
