Can you put a 110A or 125A branch breaker in the SO2040M200S Combination Service Entrance Device?<br /><br />

The ampacity of branch breakers suitable for use in this device is restricted to 15 - 100 ampere and 150 - 200 ampere. The 110 - 125 ampere breakers are restricted due to heat rise on the branch connector fingers. The 150 - 200 ampere breakers are allowed because they are designed to connect to 4 connectors fingers, rather that the standard connection to 2 connector fingers.
