Square D Meter Centres are designed to provide a compact and versa tile metering and distribution centre to suit today's residential, commer cial, and industrial markets Meter Centres now feature new combined 125/2A stacks in one sub-service as well as 3-high 125A 4 and 5 Jaw stacks. All metering stacks are shipped from the factory with meter sockets and vertical bus bars pre-installed, and require a minimum of on site labour time to install the circuit breakers and main bus links. Screw-on, sealable covers over the meter sockets and circuit breakers are finished with a grey epoxy powder coating. Provision to lock and seal the circuit breaker handles in the “off” position has been made for the convenience of utilities and electrical inspectors. This main tap box with 12A rated main bus and main 1 phase service can provide (3) AWG 4-75 MCM or (4) AWG 4-6 MCM in aluminium or copper lug size. The unit comes in sizes of height 19 in, 23 in width and 9.55 in of depth. All meter stacks are designed for CSA Type A “cold metering” in which the individual sub-service breakers are connected on the line side of the meter sockets thereby protecting the meter and all electrical equipment installed subsequent to it.
