alt Hacker NewsThanks for the additional info, I’m interested in learning more technical details about the electrical grid, like conductor size/ampacity but it’s hard to dig up information about it. I work in commercial construction and the highest voltages I ever deal with are 4160V and sometimes 5kV and 15kV, so I know a bit about medium voltage equipment and conductors but I’d like to know more about the utility side.
Are you on a mobile device? Ampacity charts for aluminum conductor steel-reinforced cable are pretty easy to find but most of them appear to be PDFs, like this one:
https://www.prioritywire.com/specs/acsr.pdf
Cables in that table are rated for between 105 to 1,751 amps under these conditions:
"Current ratings based on 75˚C conductor temperature, 25˚C ambient temperature, emissivity 0.5, 2ft/sec wind in sun"
