NEMA power cables are made in current ratings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of contact blade widths, shapes, orientation, and dimensions create non-interchangeable NEMA receptacles that are unique for each combination of voltage, electric current carrying capacity, and grounding system.

There are two basic classifications of NEMA power cables: either straight-blade or locking-blade NEMA receptacles. Numbers prefixed by ‘L’ are curved-blade, twist-locking devices; others without a leading ‘L’ are straight-blade and non-locking NEMA cable.
