Textbook Question
Chapter 10, Problem 4PA
Using the above example, determine the wire size needed for the 400-ampere service in accordance with the National electrical Code. Assume that the conductors have type THWH insulation. (Note: As a general rule, for each 100 feet of conductor length the wire size is increased one standard size because of voltage drop.)
