Buying Guide: Key Purchase Considerations For Double Meter Boxes
- Electrical capacity and configuration: Confirm the service amperage (200A is common for these options) and the number of spaces/circuits. Ensure the main breaker and meter socket setup align with local codes and utility requirements.
- Enclosure rating and weather protection: Outdoor use demands NEMA or IP ratings appropriate to your climate. NEMA 3R and IP66 are prominent for rain, dust, and corrosion resistance.
- Meter socket integration: Decide between separate meter sockets and integrated meter-main configurations. Consider compatibility with ring-type or straight-through meters and the ease of installation.
- Durability and materials: Look for corrosion-resistant materials (tin-plated copper, galvanized steel) and robust enclosures that withstand outdoor exposure and potential tampering.
- Installation and maintenance: Evaluate how easy it is to access for inspection, service connections, and ground lug installation. Padlock provisions and bypass features can aid maintenance workflows.
- Compliance and safety: Ensure UL listings and ANSI/UL standards compliance. Confirm that leakage protection, grounding provisions, and shock-safety features meet applicable codes.
- Future-proofing: Consider potential expansions (additional spaces or circuits) or migration to deeper metering configurations, and verify compatibility with standard breakers.
- Cost and availability: While prices are not listed here, assess total cost of ownership including enclosure upgrades, wiring, and support for outdoor environments.
Each option above offers a distinct balance of capacity, durability, and adaptability. When choosing a double meter box, prioritize the installation context (overhead vs underground, residential vs commercial), climate considerations, and the ease of integration with your existing electrical system. In all cases, adhering to local electrical codes and consulting a licensed electrician for installation is essential to ensure safety and compliance.
