MIL-DTL-2726; Receptacles, Receptacle Plugs, Switch and Receptacles, and Electrical Outlets, General Specification.
Covering the general requirements for power type electrical plugs, receptacles, switch and receptacle combinations, and outlets.
MIL-DTL-2726 is used in direct current (dc) circuits up to 250 volts, or in alternating current (ac) circuits up to 600 volts at frequencies up to 400Hz.
NEMA 5 is the designation for a three-wire grounding plug for 125 volt systems, so the most common selection when designing gear.
The dash 15 [5-15] indicates the amount of current the component is designed to handle. A 15 represents 15 amps, a 20 would represent 20 amps.
NEMA 1 is the ungrounded two conductor connector which is more common with some consumer equipment.
NEMA 6 is also a three wire connector, but having a different pin configuration, and used to designate 208 V and 240 V systems [250 volts max].
There are other NEMA classifications, but none that directly relate to designing electrical gear [computer and communication equipment].
An L preceding the 5 [L5-15] indicates a locking or twist-lock connection. While the absence of L indicates a standard push-in plug.
A P or R [L5-15P] should also be present to indicate the the connection is either a plug and receptacle
Note; The inlet connector needs to match the current rating of the cord, otherwise the pin configurations will be different.
The designations are of course different under the IEC standard.
However a C13 female receptacle and C14 male plug would be the corresponding types to the NEMA ones.
IEC-320-C14 [60320-14] would be the designation for a C14 type connector, 10 amps for this category.
The female connector (receptacles) have odd numbers, while the male conenctor (plugs) have even numbers.
The classification for C15 & C16 are very similar except they are keyed, the inlet has a ridge extension, the connector has a cut-away.
The IEC uses three straight blades, while NEMA uses one rounded blade contact [shown above].

Design hint; I have seen at least one engineer select a non-US standard power cord with out realizing it, or knowing any better.
Then only to get burned later when they tried to spice into it and found that the wire insulation did not match the commonly used U.S. standard.
Refer to the standard AC Wire Insulation Color Code used in the States, or in other countries.
