In a cruise ship that is 1000 ft. long and 300 ft. wide, a three-phase, 4160-V main feeder from the generator switchboard distributes 1200-kVA hotel load to 12 sectors fed by single-phase, 100-kVA, 120-V lateral feeders as shown in the following figure. Each junction of the main feeder and the lateral feeder has a single-phase, 100-kVA, step-down transformer for 120-V cabin loads. Determine 

(1) The size of the main and lateral feeders,

(2) The voltage available to the last lateral feeder at point E, and

(3) The voltage available to the last cabin at point EE. Assume (i) 0.85 pf lagging load and (ii) that both feeders have uniform size from the start to the end of the line (versus it having tapered cross section as the load current decreases from maximum at the start to minimum at the end).
