I am preparing a calculations training for several of our electricians. I wanted to go a little deeper into voltage drop and give them background into how it was developed. This is when I came across an article on the EC&M website that states that K needs to be adjusted for cable larger than 1/0. The adjustment is achieved by multiplying K by Q. Q is found by dividing the AC resistance by the DC resistance. I wanted more than one source, before putting this information out in training. I see there are a few posts in the forum that references this adjustment. Can anyone provide me with another reference other than the EC&M website? I have posted the link to the article below.
Code Calculations
Last month, we covered how the NEC addresses voltage drop through a discussion of six Fine Print Notes (FPNs) and several specific rules. This month, we’ll review examples demonstrating...
