Sdge fault current rating
Webb1 mars 2024 · #1 Greetings, To specify the panel board short circuit current rating (AIC), one thing that plays a big role is fault current at the utility side before the meter. I have always had hard time to find that information. I was wondering if there is a good assumption to consider a realistic value for fault current at the utility side. WebbFault current rating See “short circuit current rating (SCCR).” Filter The electronic device that limits certain frequency bands while allowing others to pass through. Filter designs that are integral to one-port surge protection devices are of the band-pass variety that attenuates a thin range of frequencies between line and ground mode.
