NEMA wattage labels are standardized labels defined by the National Electrical Manufacturers Association (NEMA) used on street lighting fixtures to indicate the wattage of the lamp for maintenance purposes. Additionally, various colors are used to identify what type of lamp the fixture uses. A yellow sticker indicates the lamp is a sodium vapor lamp (HPS/LPS). A blue sticker indicates the lamp ...
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.g. R17A, R17B. The IEEE 315 ...
