NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
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.
Removing the grounding pin of the appliance’s plug is unsafe, and leaves the appliance without proper grounding even when relocated and plugged into a properly grounded three-prong receptacle. [2] Additionally, since most NEMA 5-15P plugs have both current-carrying prongs the same width and rely on the ground pin for correct orientation ...
The generally used hybrid socket is also defined in TIS 166-2547, in addition to a plain three-round-pin socket, with plans to eventually replace the former and phase out support for NEMA-compatible plugs. Sockets are polarised (as in NEMA 5-15). [62] The grounded plug is similar to, but not interchangeable with, the Israeli SI32 plug.
The term plug is in general and technical use in all forms of English, common alternatives being power plug, [1] electric plug, [2] and (in the UK) plug top. [3] The normal technical term (in both British and International English) for an AC power socket is socket-outlet , [ 4 ] but in non-technical common use a number of other terms are used.
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 ...
A variant of the Australian standard 10 amperes plug has a socket on the back to allow connection of a second appliance to the same outlet. This type of plug is known officially as a "socket adapter plug" but is referred to colloquially, in Australia, as a "piggy-back plug", or in New Zealand, as a "tap-on" plug and is shown below to the right.
NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power. [1] [2]
