Ron As I understand it, based on replies to the OP and some further investigation.
The "requirement" (or strong recommendation at least) to be NRTL listed comes from: 1910.303(a) Approval. The conductors and equipment required or permitted by this subpart shall be acceptable only if approved. 1910.399 contains a number of definitions, including: Approved. Acceptable to the authority enforcing this subpart. The authority enforcing this subpart is the Assistant Secretary of Labor for Occupational Safety and Health. The definition of "acceptable" indicates what is acceptable to the Assistant Secretary of Labor, and therefore approved within the meaning of this Subpart. Acceptable. An installation or equipment is acceptable to the Assistant Secretary of Labor, and approved within the meaning of this Subpart S: (i) If it is accepted, or certified, or listed, or labeled, or otherwise determined to be safe by a nationally recognized testing laboratory; or ...other options However the exemption is in section(iv) below: 1910.302(a)(2) Not covered. The provisions of 1910.302 through 1910.308 of this subpart do not cover: (i)Installations in ships, watercraft, railway rolling stock, aircraft, or automotive vehicles other than mobile homes and recreational vehicles. (ii)Installations underground in mines. (iii)Installations of railways for generation, transformation, transmission, or distribution of power used exclusively for operation of rolling stock or installations used exclusively for signaling and communication purposes. (iv)Installations of communication equipment under the exclusive control of communication utilities, located outdoors or in building spaces used exclusively for such installations.
