Siemens Uni-PAK Metering Centers – NEC 2020 Compliant Multi-Family Solutions
Published by Sonic Electric – Your trusted source for Siemens Metering Products
The 2020 National Electrical Code (NEC) introduced new requirements that significantly affect how multi-family meter centers must be designed and installed. To support these changes, Siemens has updated its Uni-PAK portfolio of multi-position metering to fully comply with NEC 2020 standards, including:
- NEC 230.62 – Line terminal barriers for enhanced safety
- NEC 230.71 – Separate compartments for each disconnect
- NEC 230.82 – Emergency disconnect labeling (included in box)
The result is a smarter, safer, and fully code-compliant metering system designed for duplexes, triplexes, apartment buildings, and other multi-tenant residential applications. The Uni-PAK lineup includes a wide range of configurations and ampacities from 200A to 1000A across three families:
Siemens WEPK Series (NEC 2020 Metering)
- Ring or Ringless Socket Covers
- 2 to 6 Meter Positions
