22k AIC requirement from inspector on resi???

[don_resqcapt19]

Ok , but I am use to the POCO engineer quoting the fault current at my installed equipement after they calculate the impedance due to wire size and distance.
The issue is 22k at the trans?
or 22 at the metering equip?
The OP needs a letter from the POCO telling what the Fault current is at the meter and then install the properly rated equip downstream. I doub't the city would allow the rating be done by the EC unless he is a EE.

The letter from the POCO should suffice.

Around here the power company only gives the short circuit current at the secondary of their transformer.
