Where K=12.9, what is the approximate voltage-drop on a circuit where an 80-ampere, 240-volt, single-phase load is supplied with size 3 AWG copper conductors with THWN insulation, and placed 200 feet from a panelboard?



*Chapter 9 tables, table 8 conductor properties

(pg. 70-689) - CORRECT ANSWER-7.84 volts
