Can someone gives me ballpark number or guide to do quick estimate these:
1. 1500 feet run of concrete duct bank has (2) 4"C, no wires.
2. 1200 ft of 15KV, 400A cables run (conduits by other) - underground, cables would be 350KCM (good for 400A?).
3. 400 ft run of (1) 4" PVC schedule 40 conduits under crawl space, no wires.
