Below is a list of NEMA enclosure types; these types are further defined in NEMA 250- Enclosures for Electrical Equipment. Each type specifies characteristics of an enclosure, but not, for example, a specific enclosure size. Note that higher numbers do not include the lower-numbered tests. For example, types 3, 4 and 6 are intended for outdoor ...
The tables were developed under the auspices of the American National Standards Institute, C12, SC17, WG2. The standard is sponsored by NEMA, and also published as MC12.19 and IEEE Std 1377.

A song must have been sold for at least $0.49 for that sale to be logged for a given tracking week; units sold for less than the minimum price requirement in the first three months of release would not be considered for weekly charts. A "song unit" was determined by an algorithm that weights a digital song sale as 1 and respectively values 120 ...
Premium efficiency, when used in reference to specific types of Electric Motors (with a rotating shaft), is a class of motor efficiency.. As part of a concerted effort worldwide to reduce energy consumption, CO 2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many countries have introduced, or are planning, legislation to encourage the ...
