Yes, I think these equations are used to obtain the qc1/qc2 value if you are calculating the amapacity of conductor assuming a wind. Equations (5a or 5b) are used to obtain qcn if you are calculating the amapacity assuming no wind, e.g. conductor in a substation surrounded by buildings. I'm...
I'm trying to determine the ampacity rating of three 1590 AAC in parallel arranged in a flat configuration 2 inches apart. I have calculated the ampacity for a single conductor using the IEEE method and understand how to calculate the proximity effect of the conductors. Is there any additional...
