All NEMA 1 devices are two-wire non-grounding devices (hot-neutral) rated for 125 V maximum. 1-15P plugs have two parallel flat blades, 1⁄4 inch (6.4 mm) wide, 0.06 inches (1.5 mm) thick, 5⁄8–23⁄32 inch (15.9–18.3 mm) long, and spaced 1⁄2 inch (12.7 mm) apart.

In older plug designs both blades were the same width, so the plug could be inserted into the receptacle either way around. Many plugs manufactured since 1948 are polarized; the neutral blade is 5⁄16 in or 7.9 mm wide, 1⁄16 in or 1.6 mm wider than the line blade, so the plug can be inserted only one way. Polarized 1-15P plugs will not fit into unpolarized receptacles, which possess only narrow slots. Polarized 1-15P plugs will fit 5-15R grounded receptacles, which have the same wider slot for the neutral blade. Some devices that do not distinguish between neutral and line, such as internally isolated AC adapters, are still produced with unpolarized narrow blades

Hubbell’s first design was a socket which screwed into a lampholder (like the early lampholder plugs), but with a separable plug with pins (U.S. Patent 774,250) or blades (US patent 774251).

On November 8, 1904, Harvey Hubbell II patented the first detachable electric plug in the United States. The Separable Attachment-Plug, US patent number 774,250, followed Hubbell’s electric switch design in 1891 and his patent for the pull-chain electrical light socket in 1896.
