Miami Gardens is now requesting these calculations to justify the kAIC rating of a new MB when doing any service upgrade. I have made calculations according to a letter from FPL that has the available fault current at the transformer and went from there.
Do these look okay? If I get a number below 10kA, can I say that a 10kAIC rated main breaker is the minimum required and that a larger rated main breaker can be installed (like a 22kAIC rated MB)?
This seems like overkill by Miami Gardens but they require it so I have to provide it...
