Texas Journeyman exam practice question · Wiring Methods & Materials

A raceway has 1.00 square inch of internal area and the supplied allowable fill is 40 percent. What conductor area may be installed?

A2.50 square inches
B0.25 square inch
C1.40 square inches
0.40 square inch

Why D is correct

Allowed conductor area equals raceway area times the supplied fill percentage. One square inch times 0.40 gives 0.40 square inch; the calculation does not divide by the percentage.
