All NEMA 6 devices are three-wire grounding devices (hot-hot-ground) used for 208 and 240 V circuits and rated for 250 V maximum, with the 6-15, 6-20 and 6-30 being grounding versions of the 2-15, 2-20 and 2-30, respectively. The 6-15 resembles the 5-15, but with collinear horizontal pins, spaced 23 ⁄ 32 in (18.3 mm) center-to-center. The 20 ...
The lens assumes a crop factor of roughly 1.5, and therefore is not usable with on full-frame or 135 film cameras. In 2013, Sigma announced that the lens would be replaced by a redesigned model designated as the Sigma 30mm f / 1.4 DC HSM A; the new lens went on sale in March of that year in Canon, Nikon, and Sigma mounts.

4 and 4X: Watertight. Must exclude at least 65 GPM of water from a 1-inch nozzle delivered from a distance not less than 10 feet for 5 min. Used outdoors on ship docks, in dairies, in wastewater treatment plants and breweries. X (as 4X) indicates additional corrosion resistance. 5: Dust-tight.
This diagram was created with Inkscape, or with something else. This diagram uses embedded text that can be easily translated using a text editor. This version simplified from my table:NEMA receptacle pins.svg File:NEMA receptacle pins.svg by removing the bottom row's 3-phase power plugs and IEC computer connectors, as a way to simplify the table.
The Sigma 12-24mm f/4.5-5.6 EX DG HSM is a professional-level wide-angle zoom lens made by Sigma Corporation. [1] At launch it was the widest rectilinear lens available for full-frame 35mm SLR cameras, providing a field of view of 122 degrees.
Bill Whitlock, president of Jensen Transformers, writes, "never, ever use devices such as 3 to 2-prong AC plug adapters, a.k.a. 'ground lifters', to solve a noise problem!" [ 5 ] Whitlock relates how an electrical fault in one device that is connected to its electricity source through an ungrounded cheater plug will result in dangerous, high ...
NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power . [ 1 ] [ 2 ]
The J1772 5-pin standard supports a wide range of single-phase (1φ) alternating current (AC) charging rates. They range from portable devices that can connect to a household NEMA 5-15 outlet that can deliver 1.44 kW (12 A @ 120 V) to hardwired equipment that can deliver up to 19.2 kW (80 A @ 240 V). [2]
