I think the simple answer is no. The NEC deals primarily with installation wiring and not with equipment plugged into that wiring. A phrase similar to "where listed equipment is installed" is found in many sections of the code, generally where special installation conditions are acceptable which would not be generally accepted. For instance, Article 645 deals with computer rooms. You are allowed to use the special provisions of the article if, among other things, 645-2(c) Listed information technology equipment is installed.
As a general rule, the NEC does require listed equipment within the building wiring such as receptacles, panelboards, etc. But, the code does not require that all equipment have a safety agency listing. It is an article by article issue. A specific listing by UL is never required. If listed equipment is required, the listing must be from a NRTL (Nationally Recognized Testing Laboratory). A list of NRTL's may be found on the OSHA website. At least as far back as 1982 some articles in the code required listed equipment. The NEC is issued every three years. It is not a regulation. It only has the force of law when adopted by a legal jurisdiction -- town, city, county, state, etc. And, even though the NEC is updated every three years, local legislation may not be. There are some cities whose electrical code ordnance is the NEC from as far back as 2988 or earlier. John P.
