Re: NEMA/NEPA/IEEE
Sahafi, your question is too vague to even attempt an answer. I trust this will help a little and maybe you can put together a more definitive question.
NEMA is the National Electrical Manufacturers Association. They have developed a set of NEMA Standards of the years that govern how they make things. For instance, you purchases a transformer with secondary spades, the spades have a hole configuration that permits you to use any other manufacturer's standard lugs. and bolt them to the spades. That is called a standard NEMA drilling.
NEPA, I think you are referring to the NFPA which is the National Fire Protection Association. The NFPA is responsible for the NEC as well as a host of other Codes. They produce many standards and Codes from fire codes to mechanical codes to building codes. These are all done through the consensus process. That means that no more than one-third of the panel can be made up of labor, manufacturers, testing, etc. On my panel, I represent the electric utility industry.
IEEE is the Institute of Electrical and Electronic Engineers. They have produce some "how to" type books such as the IEEE buff book and the IEEE blue book. For instance, the IEEE blue book suggests a way to use a current limiting device to protect a circuit breaker if you can guarantee that the circuit breaker will be passive in the first one-half cycle. This would be an old and massive air frame breaker or an adjustable trip breaker where you could delay the opening.
I know this doesn't answer your question but I would recommend you contact some of the manufactures for guidance. Square D, Bussmann, Eaton, etc. would be happy to help you with your quest.
