Appendix A. United States design standards There are basic standards to adhere to when designing electrical systems. The only standards to be used in the United States are the American National Standards Institute (ANSI), National Electrical Manufacturers Association (NEMA), and Institute of Electrical and Electronics Engineers (IEEE) Standards. These standards define all the electrical requirements and rules necessary for the connection and use of electricity. The commonly known National Electric Code (NEC) must be followed when installing any electric service up to 600Volts. The IEEE color book publications that apply to IT installations in different facilities are listed below in Table A-1. Table A-1.
