NETA
ANSI/NETA ECS-2024 is the standard for electrical commissioning specifications for electrical power equipment and systems. It is published by NETA, the InterNational Electrical Testing Association, and carries the American National Standards Institute designation. It addresses commissioning at the system level: the functional and integrated tests that show installed equipment works together as designed once equipment acceptance testing is done.

Where the acceptance and maintenance specifications from the same publisher focus on testing individual pieces of equipment, this document concerns the installed system as a whole. Its subjects include verifying that protection, control, interlocking, metering and alarm functions operate together, confirming correct sequences of operation, and the checks made when the system is first energized and brought under load. Commissioning agents, testing firms, owners and engineers use it to plan and document that work in a consistent way, so that the commissioning record shows what was verified and under what conditions. System tests build on equipment acceptance results, so the two are normally used together. Work on energized systems brings its own hazards; read it alongside the owner safety program. The few pages in this encyclopedia that cite ANSI/NETA ECS-2024 explain the related tests in general terms and point the reader to the document for the governing procedures and criteria.
