Well, Rich,
I guess that's what happens when I start thinking (typing) too quickly. Oh well, I knew what I wanted to say. And, I sincerely thank you for this clarification and all of your always accurate emails and thorough attention to details.

Be careful here. 1. NRTL "approval" is NOT mandated through legislation (see points 3 and 4 below). 2. NRTL certification is NOT for equipment intended for the commercial environment, but for equipment intended for use by employees in the workplace. 3. 29 CFR Part 1910, Subpart S applies to employers, not to equipment manufacturers. 4. Subpart S has two alternatives for employers: a) employees may use equipment with an NRTL mark, or b) employees may use equipment the employer has tested and found to be safe according to various safety codes. Clearly, the easy way for employers to comply is to only buy and use equipment that has an NRTL mark. (As manufacturers, it behooves us to obtain the voluntary -- for us -- NRTL mark.) 5. Products intended for all other environments are subject to the local electrical code, which generally is the NEC, which invokes "listing." As a general rule, NRTL certification satisfies "listing" under the local electrical code.
