Eaton's Main Service Modules are part of the Gangable Metering offering, which consists of a Main Service Module used in conjunction with a Meter Stack to make a custom metering lineup. The Main Service Module can be main lug, main circuit breaker, main fusible switch or bolted pressure switch. Gangable Metering is often used in large condominiums, strip malls and light commercial applications where more than six units are metered, or there will be a future need to add more units.
