My local code requires alternate egress paths where a switchboard has a prospective short-circuit current of not less than 15 kA.
I have a board that has an integral ATS capable of switching between the building supply (from MSB) and the standby generator supply (from generator switchboard).
There is also a 120 kVA UPS/battery arrangement connected to the switchboard.
Any ideas where to begin with this calculation? If anyone could recommend a design guide that is applicable to this type of install etc that would be great!
