The 14-30 has a rating of 30 A, and an L-shaped neutral blade. The 14-50 has a rating of 50 A, and a straight neutral blade sized so that it does not mate with 14-30 connectors. NEMA 14-50 devices are frequently found in RV parks, since they are used for "shore power" connections of larger recreational vehicles.
NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power . [ 1 ] [ 2 ]
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 variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. [1 ...
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.

A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.
