Have existing switchgear . ( 1600 bolt-loc feeds I-line panel , 400 amp I-Line breaker feeds I-Line panel , 200 amp I-line breaker feeds 200 amp main breaker Siemens BQD panel ) . I have all the I-lines with 18,000 aic or more rateings . The BQD branch breakers are all 14,000 aic rated .The distance from the the main switch to this last panel is about 150ft . Is this a concern that we should consider having a EE go thru and verify the AIC rateings ?
