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.

Simply match your NEMA plug or power cord connector that you are looking for with the corresponding clickable “SPDS item number”. Need help constructing the optimum NEMA power cord for your application? Simply call 408-871-7928 or email sales@signalandpower.com for expert advice and guidance through your power cord or power cord plug adapter design. SPDS proudly offer the widest selection of NEMA plugs and receptacles power cords.
