Does anyone have a PDF or some type of reference on typical short circuit values for their service? .........
have you considered calling them and asking?Does anyone have a PDF or some type of reference on typical short circuit values for their service? .........
For where? (IIRC there was a fairly long thread which covered that in the last year- "network distribution" etc).
no such thingTypical underground service.
no such thing
Mid-town Manhattan or the "weeds" of Westchester Co (if such a place still exists)?
Length of drop or lateral, size of conductor and type plays into it, the longer the drop, the lower the current. Or are you looking for a starting point? Such as the transformer terminals?
See https://forums.mikeholt.com/threads/nyc-power-outage.150621/, it has a ton of info.
I am sure that across the ConEd system there are huge variations in the available fault current. On a recent Mike Holt webinar, an engineer that works in the networked areas says that there are locations where it exceeds 200kA and others where it is below 100kAGood info- but nothing I'm seeing on typical service short circuit values.

No, I don't and not 100% sure that it was one of Mike's, it could have been one of Thomas Domitrovich's. They both have youtube channels, but not idea of exactly what one that information was in.No surprise- he is correct. But I'm looking for official documentation. Something that I can site.
Have a link btw to the webinar?

Official documentation has to come from the utility on a case by case basis.
You ask the POCO during the application process?So how do I know what equipment so select? How do I know a service change is up to code?

Again, as I have said and some others have said as well, there is no such thing as typical.Haven't here- but to often I've been told "assume 200,000 amps"
