Correct answer to question 13056
- D: 80 %
Explanation
The neutral of a 120/240 V 3-wire circuit carries only unbalanced current and is not counted, so there are 3 x 2 = 6 current-carrying conductors and 4 to 6 conductors require 80 %. Counting the neutrals as well (9 conductors) leads to the wrong 70 % factor.
