I am involved in a lighting project with 3 sports fields. The customer wants all lighting to be manually controlled from one central location. The highest field lighting load is 55 kva @ 480 v (115 amps). The approx wire length from the proposed 480 panel to the field is 1000 ft. I would like to limit voltage drop to 3%.
If the field was supplied by a single 150 amp feeder the wire size calculates to 4/0. Is this reasonable?
Is there a 30A limit for exterior lighting? If so would 5-30 amp cb?s with #1 feeder be preferable.
Should primary service to a transformer be considered ?
HELP !
