Largest 120/208 volt service

How did you end up dealing with 200ka fault current?

What you describe is typical, not the exception in NY.

4000-amp KRP-C fuses with 300 kAIC

I'm going to look those up, I need them.

Me too. Seems like taking service at MV and distributing that around rather than sending that much 208 around from one (or 4) locations would be more efficient.

Depends on who is going to maintain things. Not as many people are trained to work with medium voltage, and those that are typically want more pay than those that aren't. But one has several things to look at before making such decision. Already too many general maintenance guys in some places that probably shouldn't mess with electric as is, they certainly don't need to even have a chance at doing anything with medium voltages.

Nope.
Could be this guy, BTW much better sub-metering system.

Wish all panels looked like that good
