Rating of utility service conductors in NYC

[Tainted]

Con-Edison usually provides 500MCM copper service conductors into NYC buildings

I know utilities have their own method for determining ampacity of their conductors, but does anyone here know what their 500MCM copper are rated for or the methodology used? Surely it's not as simple as looking at the NEC tables, but is 380 amps per every set of 500MCM copper a good estimate?

ut is 380 amps per every set of 500MCM copper a good estimate?

Not for a utility...it is likely much higher than that. Also, they size their conductors based on known real world loads, not the vastly inflated loads that result from the use of Article 220.

I figured the 500MCM might be higher, but I just wonder what value or at least an estimated value of the ampacity would be
