A meter main is a combined electrical assembly that integrates a utility meter socket and a main circuit breaker into a single enclosure. It serves as the primary point where utility power enters a building, simultaneously handling metering for billing purposes and providing overcurrent protection for downstream distribution. This compact design simplifies installation and reduces the number of individual components required at service entrance.
