When greater than six branch circuits are required, the NEC requires a main disconnect and overcurrent protection device ahead of the meters. A fusible main switch module serves as this single point of disconnect and overcurrent protection. A fusible main switch module consists of a pull section to house the lugs for connecting to the utility feed and the main switch. A compression lug landing kit is included with each main switch module.
