The dept of water and power said they will supply my 1600 amp apartment switchgear (208Y, 120V, 3 phase, 4 wire) with a max fault current of 62KAIC. The motor contribution brings it up to 63.66 KAIC.
We originally spec'd a 65 KAIC panel, but the plan checker is saying we must provide a 100KAIC panel, for an additional factor of safety. Can he legitimately require something that goes beyond the requirements of the DWP and the engineer of record, and the calculated loads? If so, why?
At this stage of the project, we can't afford the switchgear upcharge, nor the opportunity for supplier to revisit their price quote.
