It integrates a meter socket with a main breaker and four spaces for additional circuits. While not a 320-amp unit, it offers a compact, weather-resistant option that can be used in spaces with limited depth or where a combined meter and distribution solution is beneficial. It supports outdoor reliability through NEMA 3R rating and corrosion-resistant construction.
Buying Guide: Key Considerations for 320 Amp Meter Sockets
- Current rating and compatibility: Ensure the socket is rated for 320 amps and compatible with your service entrance and meter base. Check whether the unit supports ringless, bused, or bypass configurations to match maintenance needs.
- Bypass and safety features: A bypass lever or switch allows safe maintenance without service interruption. Look for secure lockout provisions, tamper-resistant designs, and clearly labeled terminals for safe operation.
- Enclosure and weather resistance: Outdoor use requires a NEMA or UL-rated enclosure (e.g., NEMA 3R or equivalent). Coatings, G90 galvanized steel, or powder coat finishes improve long-term durability in harsh environments.
- Terminal configuration: Four-terminal, seven-terminal, or other configurations affect how you wire feeders, service entrance conductors, and downstream loads. Plan for ease of access and future upgrades.
- UL/MEG approvals and certifications: Look for MEG (Meter Equipment Group) approvals or other third-party certifications that indicate compliance with industry standards and safety requirements.
- Installation considerations: Consider pad mounting vs. surface mounting, required mounting hardware, and accessibility for future meter changes. Quick-install features can reduce labor costs.
- Compatibility with existing meters and loads: Verify that the socket matches your meter type, socket rings, and lugs, especially if you plan to reuse or upgrade meters in the same service.
- Maintenance and serviceability: A design that enables easy field servicing, including accessible lugs and lever bypass, can reduce downtime during inspections or repairs.
- Warranty and support: Check for manufacturer warranties and availability of replacement parts. Longer warranties can be an indicator of durability and manufacturer confidence.
These considerations help ensure you select a 320 amp meter socket that provides safe operation, straightforward maintenance, and durable performance in outdoor environments. Compare the listed options for bypass capabilities, ringless design, terminal count, and enclosure ratings to pick the configuration that best aligns with your installation needs and local code requirements.
