Current (ampacity) Notes: The current ratings shown in the table are for power transmission and have been determined using the rule of 1 amp per 700 circular mils, which is a very conservative rating. For reference, the National Electrical Code (NEC) notes the following ampacity for copper ...

I have a max VD of 5% per NEC -- I understand that the NEC does not specify VD for service conductors, but since it specifies it for all others, I'm just going with that.Now, the fun part. My question is not really about the calcs, but rather what values for R to use. The ...
