Where in the National Electrical Code (NEC) does it discuss the acceptable methods for temporary outlet panel wiring?
Article 305 of the NEC addresses the acceptable methods. OSHA relies on NEC’s specifications for certain matters concerning electrical systems. We have included the entire current NEC by reference in Subpart K of 29 Code of Federal Regulations Part 1926. Paragraph 1926.402(a) references the NEC, and states: “If the electrical installation is made in accordance with the National Electric Code ANSI/NFPA 70-1984… it will be deemed to be in compliance with §§1926.403 through 1926.408…” Apart from some exceptions that are not applicable here, compliance with the NEC also meets OSHA’s electrical requirements. If you need additional information, please contact us by fax at: U.S. Department of Labor, OSHA, Directorate of Construction, Office of Construction Standards and Guidance, fax # 202-693-1689. You can also contact us by mail at the above office, Room N3468, 200 Constitution Avenue, N.W., Washington, D.C. 20210, although there will be a delay in our receiving correspondence by mail.
