This makes multi-circuit NEMeter systems particularly attractive for:

  • Commercial office buildings and shopping centers
  • Apartment complexes and multifamily properties
  • Industrial manufacturing facilities
  • Tenant electrical submetering
  • Branch-circuit energy monitoring
  • Data centers and equipment rooms
  • Energy management and building automation systems
  • Electrical energy-code compliance applications

By consolidating multiple monitoring points into one system, contractors can reduce the amount of hardware required while providing building owners with greater visibility into electrical consumption.


Flexible Current Transformer Options

Every electrical installation presents different challenges, particularly when working in existing facilities.

NEMeter systems support multiple current transformer configurations, including solid-core, split-core, hinged, and Rogowski CT options, depending on the meter and application.

This flexibility allows electrical contractors to select the most appropriate solution based on conductor size, available installation space, electrical load, and accessibility.

Split-core and hinged CTs can be especially beneficial for retrofit projects where minimizing disruption to existing electrical installations is important.

Rogowski CT options provide additional flexibility for applications involving larger conductors or challenging installation conditions.


Revenue-Grade Accuracy for Reliable Energy Measurement

Accuracy is one of the most important considerations when selecting an electrical submetering system, particularly when the information will be used for tenant billing, cost allocation, or energy management.

NEMeter multi-circuit systems offer high-accuracy metering, with configurations supporting ANSI C12.20 Class 0.2 accuracy.

Revenue-grade measurement helps property owners and facility managers obtain dependable electrical consumption data for applications such as:

  • Allocating electrical costs between tenants
  • Measuring individual departments or production areas
  • Tracking energy consumption by equipment
  • Identifying abnormal electrical usage
  • Evaluating energy conservation initiatives
  • Supporting energy management reporting

For commercial property owners, accurate submetering can help establish a more transparent method of allocating electrical expenses based on actual usage rather than estimated consumption or square footage.

For industrial facilities, detailed electrical monitoring can help identify energy-intensive equipment and support decisions about operating schedules, equipment upgrades and energy efficiency investments.


Flexible Communications – BACnet, Modbus, Ethernet, Cellular Connectivity
