Leviton 400A Outdoor Meter Main Combo

Leviton’s LS140-S5D combines a meter main with a load center designed for rough-in wiring before breakers are installed. It features tin-plated copper bussing for superior conductivity and includes a provision for a field-installable main breaker, enabling flexible configurations for future upgrades or code changes. The ringless design reduces potential bypass paths, supporting safe service disconnect and reliable operation in outdoor environments.
Cooper B-Line 324 N Meter Enclosure

The Cooper B-Line 324 N is a narrow 400A meter enclosure with 4 jaws and a single-phase, 3-wire configuration. Its rugged design supports outdoor use with a focus on compact space savings in the service area. This enclosure is well-suited for applications requiring a reliable disconnect and a streamlined footprint, offering straightforward maintenance and durable performance under varied weather conditions.
SIEMENS 48104-02GP RingleSS Meter Socket

The SIEMENS 48104-02GP offers a ringleSS type meter socket with a 320A continuous rating and 400A maximum. It is designed as an outdoor enclosure (NEMA 3R), featuring a clamshell lever bypass and a 1-phase, 3-wire configuration. This setup is appropriate for installations requiring reliable disconnect functionality with a robust weather-rated enclosure and a straightforward bypass mechanism.
Milbank U7040-RL-TG 200A Meter Socket

Milbank’s U7040-RL-TG model provides a ranger of service options with overhead or underground applications. While rated at 200A, it is included for comparison of design approaches between 200A and 400A solutions, highlighting how different enclosure families handle bypass configurations, ringless designs, and field modifications in outdoor settings.
Eaton HP4040SHPVCSR Solar Ready

Eaton’s HP4040SHPVCSR is a 400A solar-rated ready solution for outdoor installations. The unit supports integration with solar-ready systems, offering a reliable disconnect option while maintaining robust protection. This model is suitable for users planning to incorporate solar or hybrid energy systems within a service-rated meter socket assembly, ensuring compatibility with modern resilience requirements.
Buying Guide
- Amperage and voltage: Confirm that the enclosure supports 400A service and compatible voltages (typical 120/240V single-phase). Some models offer 320A continuous with a 400A max rating, which influences protection and future expansion.
- Enclosure type and rating: Outdoor, weather-rated enclosures (NEMA 3R, G90 steel) resist moisture and corrosion. RingleSS versus ringless designs impact bypass strategies and maintenance access.
- Disconnection and bypass: Look for lever bypass or field-installable main breakers. A reliable disconnect enhances safety during maintenance and power shutdowns.
- Jaw configuration: 4-jaw or 5th jaw provisions affect how the service conductors connect to the meter base. Ensure compatibility with existing feeders and lugs.
- Conductivity and busing: Tin-plated copper bussing improves conductivity and longevity under load. Verify compatibility with your panel and conductor sizing.
- Expansion and future needs: Some units allow field add-ons (e.g., main breakers). Consider whether you might add PV or backup power later.
- Installation considerations: Outdoor installations require proper conduit, grounding, and clearances. Ensure that mounting and wiring paths align with local codes.
- Brand support and documentation: Favor brands with comprehensive manuals, installation guides, and readily available replacement parts to simplify maintenance.
The selections above cover practical configurations for a 400 amp service with disconnect capability, emphasizing safety, durability, and compatibility with outdoor installations. When selecting a unit, align features with your electrical design, local code requirements, and future expansion plans.
