Explore the Variety of NEMA Power Cord Types

A NEMA extension power cord is an essential component for AC mains electricity in North America and other countries that adhere to the US National Electrical Manufacturers Association (NEMA) standards. These power cords come in various types, each featuring specific NEMA connectors. These connectors can be power plugs or receptacles/outlets designed to accommodate NEMA power plugs.

Most NEMA connectors are straight-blade and non-locking, identified by two numbers and a letter "P" or "R" followed by the second number. The two numbers are separated by a dash, indicating the specific configuration of the connector.
