Buying Guide
What to consider when choosing a 277/480V 3-phase metering solution
- Metering type and scale: Choose between inline meters, panel-mounted options, or full enclosure kits based on space and load requirements.
- Electrical configuration: Confirm 3P4W versus 3P3W compatibility and whether a neutral is needed for your system.
- Data interface: Look for RS-485 (Modbus), Pulse Output, and cloud-ready gateways to match your BAS or AMR needs.
- Compliance and safety: Ensure UL/cUL or ANSI C12.1 conformity and enclosure ratings suitable for indoor or outdoor placements.
- Installation complexity: Pre-assembled panels and kits reduce field labor; verify knockouts and conduit connections.
- Future scalability: Consider TOU support, real-time data access, and gateway options for expanding reporting to tenants or property managers.
Common buyer questions
- What is the difference between a 3P4W and a 3P3W setup?
- Do these meters support cloud-based energy data reporting?
