Three-phase services carry more terminals to manage, and that's exactly what this 7-jaw base is built around. It gives each phase and neutral conductor its own dedicated contact point, so the meter reads accurately even as the circuit complexity increases compared with a standard single-phase setup.
The enclosure is formed from 1.2–2mm galvanized steel and finished with an electrostatically applied, baked gray powder coating, which gives it strong resistance to rust and surface wear across a wide range of climates. With a 600V rating built in, the unit is engineered to hold up under the higher electrical stress that three-phase distribution can place on a metering point.

05
Design Features
7 Jaw (7 Terminal) Design: With seven individually engineered jaws, the socket maintains firm, low-resistance contact across every conductor position, which matters directly for metering accuracy and for keeping the connection stable as current levels rise.
Durable Construction: The 1.2–2mm galvanized steel body resists dents, impact damage, and long-term corrosion better than thinner-gauge alternatives, which is particularly relevant for three-phase installations that often sit in higher-traffic commercial or industrial areas.
Easy Installation: Mounting holes come pre-positioned, and clearly labeled terminals reduce the chance of a wiring mistake - a meaningful time-saver on three-phase jobs where there are simply more connections to get right.
Protection Features: Built to NEMA 3R protection standards, the enclosure keeps rain, snow, and dust out of the internal contacts, and select models can accept a lockable cover for sites where unauthorized access is a concern.
Application Areas
Residential Properties with High Power Needs
Homes with electric vehicle chargers, central air conditioning, and other high-draw appliances often need more metering capacity than a basic residential socket provides - this base is sized to meet that demand.
Small Commercial Establishments
Retail stores, offices, and workshops that draw more power than a typical household, but still fall within a manageable service size, can use this base as a dependable metering and distribution point.
Industrial Auxiliary Systems
Facilities that run separate low-power sections off a main industrial supply can use this socket to give those circuits their own dedicated, independently monitored metering point.
Customization
We understand that every project may have unique requirements. Our 200A meter sockets offer customization possibilities as follows:
Color Customization
The standard baked gray powder coating can be swapped for a different color to match branding requirements or blend with a specific building's exterior.
Terminal and Wiring Configurations
Terminal sizing and arrangement can be reconfigured for projects with non-standard wiring layouts or space-constrained panel locations.
Conduit Hub Adaptations
For hub requirements outside the standard 1" to 2-1/2" range, custom sizes and entry positions can be arranged to match existing infrastructure.
Enclosure Customization
Housing dimensions can be adjusted to fit unusual mounting spaces without compromising the structural strength of the design.
Replacement Block Assemblies Compatibility
A compatible replacement block, PB200-7J, is available separately to support maintenance and future servicing without replacing the full unit.
