NEBS Certifications and What They Mean

Network Equipment-Building System (NEBS) certifications were developed by Bell Labs in the 1970s. One of the main goals of the certifications was to standardize electricity conduction equipment, such as power inverters, that is used in Regional Bell Operating Centers (RBOCs). Standardizing the equipment makes it easier to achieve proper safety measures, predict the performance of the equipment, and helps simplify equipment maintenance.

Levels of NEBS Certification

There are three levels of NEBs Certification that are referred to simply as Level 1, Level 2, and Level 3. In this entry, we focus on what the levels of certification mean concerning the needs of end users. The information can help you determine whether your company or organization could benefit from implementing power inverters that have a NEBS certificate.

Level 1

The first level of NEBS certification applies to equipment that conforms to the personnel and equipment safety requirements of GR-63-CORE and GR-1089-CORE. However, this level of certification doesn’t address the operability requirements for inverters after installation. Consequently, Level 1 certification typically applies to inverters that are in the testing phase. Conformance to the safety requirements above helps make the hardware safer to test.

Level 2

The second level of NEBS certification applies to equipment that also conforms to the personnel and equipment safety requirements of GR-63-CORE and GR-1089-CORE. In addition, this level of certification establishes operating requirements for hardware that is used in a specific, controlled type of operating environment, such as a data center. Level 2 certification applies to equipment that doesn’t operate under adverse conditions, such as the ones listed below.

Level 3

The third level of NEBS certification applies to equipment that conforms to the personnel and equipment safety requirements of GR-63-CORE and GR-1089-CORE and is designed to operate under adverse conditions, including: unusual temperatures, vibration, and airborne contaminants. Because these conditions are quite common in industrial work environments, Level 3 certification tends to be the one that best suits the requirements of industrial companies and organizations.
