All of our panels are “Series Rated” by Square D. Example: A Series Rating on a QGL main breaker indicates that the 65kAIR main breaker and 10kAIR branch breaker, QO or QOB, combination have been tested and certified to UL. Both breakers may trip but safety will not be compromised. http://www.lyntec.com/139-0407_Series_Ratings.pdf.
