ARTICLE 411. LOW-VOLTAGE LIGHTING
ARTICLE 411. LOW-VOLTAGE LIGHTING411.1. Scope.‚ÄÉThis article, which was new in the 1996 NEC, covers the installation of so-called low-voltage lighting. This lighting, although power limited, is not necessarily power limited to the same degree as Class 2 or Class 3 circuits in Art. 725. For example, the upper limit on voltage is 30, but the upper limit on current is 25 A, making the potential available power roughly 6 times that of a Class 2 signaling circuit. Recent changes, largely driven by LED technology, have resulted in extensive systems covered by this article that operate entirely within Class 2 limits, and the article title now simply refers to low voltage. Generally the specified limits are 30 volts ac and 60…
