My supplier cannot find a manufacturer that offers a 200A.
120/240V. meter/main commercial panel with test bypass that is rated over 22 KAIC. Anyone else run into this? Fused panels are available but the client wants breakers.

22K panels are usually in stock. I am getting the specified AIC ratings off of the engineered drawings or utility reports. Seems like most of the jobs we do are 42-65 K rated.

If impendence is less then Aprox. 2.2 then you gotta jump up to 22000 .
50 kva secondary 208amps.
2.2 at 208 volts single phase. APROX.
I get APROX. 9454 , Its less if a distance away.
Check with Eng. But power companys always go high so do designers. You never wanna be lower then whats really required!!!!

If they don't have it, they'll manufacture what you need for your specs.... I believe they use Siemens gear
