Hello,
I am working on the panel schedule, and I noticed that some panel has MLO, and some panel has MCB.
I believe that the omission of a main breaker in many of these cases is due to cost and perhaps in some cases available panel real estate. Is there any rule for MLO or MCB?
I am not quite sure the reason why.
