Terminals for the neutral (grounded) conductor in general, and for receptacles, plugs, and connectors specifically, are required to be substantially white in color [NEC 200.9, NEC 200.10 (B)], and if the terminal itself is not visible, the hole leading to it must be marked with the word "white" or the letter "W".
NEMA connectors implement these requirements. The NEC also permits grounding-type receptacles in non-grounded wiring protected by a GFCI; this only applies when old non-grounded receptacles are replaced with grounded receptacles, and the new receptacles must be marked with 'No equipment ground' and 'GFCI Protected' . 240 V receptacle faces

[6] Founded in 1926, it advocates for the industry and publishes standards for electrical products. Notably, the form of US household electrical outlets and plugs is specified by NEMA.
The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).
The NEMA 5-15 plug has two flat parallel blades like NEMA 1-15, and a ground (earth) pin. [48] It is rated 15 A at 125 volts. The ground pin is longer than the line and neutral blades, such that an inserted plug connects to ground before power. The ground hole is officially D-shaped, although some round holes exist and many plugs have round ...
