I'm working on an excel voltage drop calculator and have been a little confused by a few other calculators that I've seen related to Table 8. My understanding is that the conductor resistances from Table 8 are only valid for DC systems and Table 9 should be used for AC.

What are your thoughts and the consensus of for using the DC resistances?
