In parallel cables, the phase current is divided between two or more conductors. Typically in paralleling cables, the size and length of each cable are the same, and the current flow is equally divided between the parallel conductors. If the conductors (or lengths) are of unequal size, then the current will not be distributed ... WebFeb 28, 2024 · Of course 2 runs of AWG #6 would be 3.951 mΩ. The voltage drop from one run of AWG #8 would be 6 Amperes x 12.56 mΩ = 75.36 millivolts. The voltage drop from one run of AWG #6 would be 6 amperes x 7.9 mΩ = 47.4 millivolts.
