Group metering is a service entrance product line that consists of a main device and multiple meter sockets in one enclosure or several connected enclosures. Group metering allows the customer to install a multiple tenant-metering device in one location while providing a space and installation cost savings. Meter Packs are supplied as one complete unit and the user cannot "add" additional meter sockets to the unit in the future. The most common application for Meter Packs is garden apartments, small condominiums and townhouses where six or less units are metered through one centrally located Meter Pack.
