Application range of methods in IEEE1584

Hello everyone,

The application range for the empirical method is clearly defined : 208V to 15kV and a bolted fault current between 700A and 106kA.

But for the theoretical method, what is the applicable bolted fault current range?
Can it be used for any voltage?

The position about the type of bolted fault current is also not clear. Is it only for 3-phase fault? Or 1-phase fault can be treated?

How do you understand those? Do you use another standard in case of you’re out of one of the above range? READ MORE.
