Nema Guide - Nema Power Cords, Plugs & Receptacles

NEMA (National Electrical Manufacturer's Association: NEMA.org) is by far the most popular set of standards used in America and Canada for the construction of power cords and their respective connections. The NEMA plug and power cord connectors are organized by maximum power consumption requirements beginning with up to 15 amps at 125 volts all the way up to 50 amps at 250 volts.
