Buying Guide
Key considerations when selecting a 200 amp 3-phase meter base include:
- Phase configuration: Confirm 3-phase service suitability and compatibility with existing equipment.
- Amperage rating: Choose based on current demand and future load growth; 200A is common, with 320A options for higher needs.
- Enclosure and mounting: Outdoor versus indoor use; examine NEMA rating, weather resistance, and mounting requirements.
- Bypass capability: If service isolation for maintenance is important, consider bypass-equipped models.
- Configuration flexibility: Some units support 1PH, 2W, or 3W configurations; plan for expected wiring scenarios.
- Code and safety: Ensure compliance with local electrical codes and utility interconnection rules.
- Manufacturer reliability: Milbank units are common in commercial installations; consider availability of parts and support.
Practical comparison tips
- Choose best for: If bypass is critical, favor the Milbank 200A bypass model.
- Better for higher demand: The Milbank 320A options handle more load and may be more future-proof for busy facilities.
- Outdoor durability: The DISGE kit is designed for outdoor use with flexible metering configurations.
- Simple replacements: The Generic Universal meter base is straightforward for standard 200A/240V single-phase needs.
Installation and safety notes
Always hire a licensed electrician for meter base installation. Verify service conductor sizing, enclosure protection, and grounding practices. Maintain clearances around the meter base and ensure permitted access for utility meters and service personnel.
