RE: interrupt current
- transformer voltage and kVA
- conductor size and distance to the panel
- possibly load contibution downstream
The basic answer can be had from a table. A more precise answer is obtained by a calculation method. Several other threads in this forum have contributions on this topic. Have you tried a search?
RE: interrupt current
I suggest you use a good power system analysis program.

RE: interrupt current
1. Transformer kVA
2. Transformer Voltage
3. Transformer Impedance
4. Transformer Short Circuit MVA, if known
5. Cable and or bus size
6. Cable and of bus length
7. If there is a reactor, then its parameters
8. Panel number of phases

RE: interrupt current
the cable is 6-750 MCM
the length is 90 feet
what is the rating at the panel
RE: interrupt current
1. Provide requested information. It is needed for obtaining correct results.
2. Unless you just keep yourself busy.
