When greater than six branch circuits are required, the NEC requires a main disconnect and overcurrent protection device ahead of the meters. A main breaker module serves as this single point of disconnect and overcurrent protection. A main breaker module consists of a pull section to house the lugs for connecting to the utility feed and the main breaker. A main breaker module does not provide the option for compression lugs and thus, when the utility specifies compression lugs, a separate pull box is required.
