NEMA 5-15P plug and NEMA 5-15R receptacle (different scales, blade spacing is 0.5 inches (12.7 mm) for both.) Each receptacle also accepts an ungrounded plug, whether polarized or unpolarized. Typical 5-15R residential receptacle 5-20R T-slot receptacle mounted with the hole for the ground pin at the top. The neutral connection is the wider T ...
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.
Ground pins are all shown in the up direction. Reorienting 14-30 and 14-50 this way makes the diagram match most commercially available cables. Reorienting 5-15 is controversial because most residential installations use ground down, but many commercial or healthcare installations use ground up, and I'd like the diagram to be consistent.
NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power . [ 1 ] [ 2 ]
A popular choice for the latter is the NEMA 14-50 receptacle. This type of outlet provides 240 volts and, when wired to a 50-ampere circuit, can support charging at 40 amperes according to North American electrical code. This translates to a power supply of up to 9.6 kilowatts, [91] offering a faster and more efficient charging experience.
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 simplest type, designated CEI 23-50 P 17/11, has a central round hole flanked by two figure-8 shaped holes, allowing the insertion of CEI 23-50 S 10 (Italian 10 A plug unearthed), CEI 23-50 S 11 (Italian 10 A plug earthed), CEI 23-50 S 16 (Italian 16 A plug unearthed), CEI 23-50 S 17 (Italian 16 A plug earthed) and CEE 7/16 (Europlug).
SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".
