If the main panel does not have a main breaker, is the amperage rated at the combination of the service conductors or the size of the individual conductors. Thanks for your help.
We will assume it complies to the “6 disconnect” allowance since no breaker is installed. You will at that point use the size of the service condutors, rating of the enclosure ( and if an electrician the calculated load ) but in the end if you are not able to determine then do not guess.
When you say “combinaton of the service conductors”…you are kinda saying you have parallel conductors…then you would add the phase or line conductors up…but if only one set of service conductors then it would be the ampacity of that conductor in question.
