The Electrical Generating Systems Association (EGSA) is the world’s largest organization exclusively dedicated to On-Site Power Generation. The Association is comprised of over 750 companies—Manufacturers, Distributor/Dealers, Contractors/Integrators, Manufacturer’s Representatives, Consulting & Specifying Engineers, Service firms, End-Users and others—throughout the U.S. and around the world that make, sell, distribute and use On-Site Power generation technology and equipment, including generators, engines, switchgear, controls, voltage regulators, governors and much more.
One of EGSA's prime functions is to participate in the writing of national standards involving the use of on-site power, e.g. The National Electrical Code. These standards include code listings, glossaries, and guides.
In addition to these inter-industry standards, EGSA has in the past developed performance standards for engine-driven generator sets, power generation components, and accessories, and other topics including genset test methods and engine noise reduction.
Many EGSA standards are available for free download from their website:
