Sometimes called Combos, All-In-Ones, Meter Centers or Meter Mains these units are increasing in popularity as the socket and load- center or main breaker are located in one location, thus providing the contractor with a labor and material savings when installing. Application Description In addition to residential installations, meter breakers are equally applicable for rural service entrance, mobile homes, and construction site tempo- rary power. Meter breakers are most often sold in the western, southwest- ern and southeastern United States. The popularity of meter breakers is continuing to increase as more utilities deregulate and pass the responsibility of supplying watt-hour meter sockets on to the electrical contractor. Application Considerations We have the meter breaker to meet your application.
