Hey everyone. I was looking at Pyrotenax MI cables earlier today and it appears that they offer an online voltage drop calculator on their website. It requires a quick signup to use. What I ended up doing was taking their online voltage drop calculator and back calculating the impedance of a few of their conductor sizes so that I could use them in the future for a spreadsheet. When Pyrotenax was under the umbrella Pentair and Tyco, they used to publish their "voltage drop factors" which appear to be close to the impedance * sqrt(3). Anyone know if this data exists somewhere else on the internet?
