Which statement is true regarding the use of parallel conductors?

The statement that the conductors must have the same size in circular mil area is correct because using parallel conductors that are of equal size ensures that the current divides evenly among them. When conductors are carrying current in parallel, it is essential for them to have the same electrical characteristics, including the circular mil area, to maintain balanced loading and prevent overheating. If conductors of different sizes are used, one may carry more current than the others, leading to a risk of overloading and potential failure. Ensuring all conductors are of the same cross-sectional area promotes safe and efficient operation, aligning with electrical codes and standards for installations involving parallel conductors.
