NEMA connectors are power plugs and receptacles utilized for Air conditioning mains electrical power in North America along with other countries designed to use the specifications set by the US Nationwide Electric Producers Connection. NEMA wires devices are made in current rankings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of get in touch with blade widths, shapes, orientations, and dimensions produce non-exchangeable connections which are unique for every mixture of voltage, electric current carrying capability, and grounding system.

NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on typical household electric gear, and NEMA 5-15R will be the regular 15-ampere electric receptacle (electric outlet) found in the United States, and under appropriate national specifications, in Canada (CSA C22.2 No. 42, Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).

Other plug and receptacle types are for special purposes or perhaps for heavy-responsibility applications.

NEMA connections are named following an alphanumeric code comprising: prefix “L” (locking types), numerals, a hyphen, numerals, suffix “R” or “P” for “receptacle” or “plug”.

The two main basic categories of NEMA connections: straight-blade and securing. The metal conductive cutting blades are often informally known as “prongs” (as with “3-prong plug”). Numbers prefixed by ‘L’ are curved-blade, twist-securing connectors. Twist-locking kinds can be used as weighty commercial and industrial gear, where improved safety towards unintentional disconnection is required.

The numerals previous the hyphen encode the number of poles (current-carrying terminals) and cables linked to it, the voltage, and solitary- or three-stage energy. A connector with ground terminal is identified as getting much more cables than poles, e.g. two-pole, 3-wire; or four-pole, five-cable; etc. A low-grounding device may be two-pole, two-wire; three-pole, 3-cable; and so on.

The numerals following the hyphen will be the current rating of the gadget in amperes. This number is accompanied by the letter ‘R’ to suggest a receptacle or ‘P’ to suggest a plug.

As an example, the five-15R will be the common 125 V two-pole, three-wire receptacle ranked for 15 A. The L5-15R, while sharing the identical electric rating, is a securing design that is not physically appropriate for the straight-blade 5-15 style. The Five-30R has got the exact same two-pole, 3-cable configuration and 125 V rating, but is ranked for 30 A.

Although there are numerous low-grounding device kinds within the NEMA specifications, only three turn out to be in widespread use nowadays. These are the two-pole 1-15, still being used in an incredible number of structures built before the 1960s, and also the 3-pole 10-30 and 10-50.

Other kinds of NEMA connections that do not follow this nomenclature consist of: the ML collection (so-known as “Midget Locking” connectors named for diminutive size), TT (for connecting travel trailers as well as other recreational automobiles to external power sources), SS series (“ship-to-shore” connections to connect boats to shore power) as well as the FSL series (found in military and airplane applications).

The tiny opening nearby the end of the power (low-ground) blades of some NEMA plugs is utilized for convenience in production; if existing, it should be of specified size and place. Small specialized padlocks are available to match these openings, enabling “lockout” of hazardous equipment, by physically stopping placement of secured plugs in to a energy receptacle. Because a minimum of 1949, numerous receptacle gadgets are also invented to utilize these holes to hold the prongs in the receptacle slots, skocrg a corresponding latch or locking mechanism.

The cutting blades of the NEMA connector are identified in the dimensional regular as follows: ‘G’ recognizes the grounding conductor, ‘W’ recognizes the (grounded) neutral conductor, and ‘X’, ‘Y’, and ‘Z’ would be the “hot” line conductors. Single-stage connections just have a single terminal recognized as ‘X’ or two terminals, ‘X’ and ‘Y’. 3-stage connectors will use ‘X’, ‘Y’ and ‘Z’.

Criticism has been geared towards the style departing a space with uncovered prongs. This safety flaw continues to be exploited by way of a January 2020 Internet phenomenon referred to as Outlet challenge, in which conductive components, usually coins or paper clips had been dropped to the gap, causing electrical sets off, which once led to a building evacuation in Westford Academy
