NECA Revises Recommended Practice for Commissioning Building Electrical Systems

This standard describes installation procedures for commissioning common newly installed or retrofitted building electrical systems and equipment.

NECA 90-2015 Standard for Commissioning Building Electrical Systems is now available from the National Electrical Contractors Association (NECA). This standard describes installation procedures for commissioning common newly installed or retrofitted building electrical systems and equipment. It defines the process of commissioning building electrical systems and provides sample guidelines for attaining optimum system performances that conform to design, specification, and industry accepted codes and standards. This standard is not intended to cover commissioning processes for every type of electrical system and references other specific NEIS documents where such information is provided.

This edition of NECA 90 has been carefully revised and significantly expanded to reflect the latest techniques used in building and electrical system commissioning processes. This includes the traditionally separate functions of equipment startup, control system calibration, testing and balancing (including electrical load balancing as required in the NEC), functional performance testing, system documentation, and training.

Commissioning and startup processes are an essential part of the acceptance process for facilities. This recommended guide hits the mark and provides the essential references to other important testing and evaluation standards related to electrical system and equipment commissioning.  

“NECA’s National Electrical Installation Standards (NEIS) library has grown over the years, and as new technologies emerge, the NEIS evolve and keep pace,” stated Michael Johnston, NECA’s executive director of standards and safety. Johnston also emphasized that “the NEIS help professionals in developing design specifications in that they reduce and often eliminate specification writing time.”
