I am working on a SKM model of some old buildings. During a site survey, Continental Company Electrical panels were noted. These panels are type NLAB. Can anyone point me in the direction of a data sheet for these panels? I need to know the KAIC rating of them and these were installed before this information was incorporated into nameplate information. Any assistance would be greatly appreciated. Thanks!

is it possible they were before anyone even considered AIC?
 
You can take approaches:

Everything without a label is rated at 5kA

Panelboards with breakers might take on the rating of the lowest breaker AIC.

I've seen both approaches used.
 
From what I remember, Continental was acquired by GE. The NLAB panel was marketed under the GE name using the TQB branch breaker. At that time, standard UL listing for these breakers was 5kAIC, as Ron indicated. The current GE THQB breaker is 10kAIC. The "H" in the cat# was for high interrupting capacity, now a standard minimum.
