  • Standards That Help Make Life Easier

    If you want a power cord you can depend on, call NEMA Power Cords! It may sound like a super hero, it is not, but it does act as the power cord of a super hero should! I recognize I am being ridiculous, I apologize and will now stop. NEMA power cords, or National Electrical Manufacturers Association power cords are the standard models used in North America. The association is also able to supply plugs and connectors. Popular in the United States and parts of Canada, this company is able...

  • Two-Pronged Plugs: Infinite Frustration/Safety

    One of the greatest household frustrations (in the minute frustrations category, that is) is reaching to plug two-pronged plugs into outlets. Two-conductor power cords are still prevalent in consumer and even commercial and industrial contexts. While it's true that a grounding pin is an important safety feature in many power cords, it is not always necessary. In addition to its benefits as a safety feature, though, the grounding pin in a three-prong plug serves another purpose. There's no guessing about plug orientation with a three-prong plug. As long as you...

  • NEMA Power Cords: Here, There and Everywhere

    If you were to see a NEMA power cord, you would be in any one of three possible places. The first and most likely possibility is somewhere in the United States or Canada. NEMA stands for National Electrical Manufacturers Association, and since 1926 NEMA has published standards pertaining to the design and specifications of all manner of electronic components, including plugs and receptacles. A NEMA cord might as well be called a North American cord. The most common NEMA configuration, the NEMA 5-15, is characterized by its distinct, parallel flat...

  • Traveling with Electronics

    Have you ever traveled abroad and wondered if your electronics would work if you plugged them into the wall? I frequently travel, having been to 14 countries I have learned to do my research before leaving the country. The majority of the time a converter will be needed for your electronics if you are traveling outside of North America. This is because the standards set by the United States and other countries that use this system are controlled by the National Electrical Manufacturers Association (NEMA) use a set standard that...

  • Medical Power Cords

    Signal and Power Delivery Systems introduces world’s first line of low profile molded medical power cord plugs, an ideal solution for all medical and hospital installations where space is limited. Campbell, CA April 18, 2011 -- Various medical and hospital equipment applications require power cords with “green dot” certification and UL approval. Until now, power cords for medical applications containing the NEMA 5-20P, NEMA 6-15P or NEMA 6-20P needed to use expensive and bulky assembly style or molded plugs. This new line of products from SPDS is the world’s first...

  • Brand NEW and UNIQUE AUTO-LOCKā„¢ System for IEC

    For years, Networking and Medical Professionals have strived to find solutions for cable retention.  Advanced Information Technology has always required connectivity and advocated new methods of preventing unintentional disconnection.  Quail Electronics is pleased to introduce a new and exciting solution to power electrical connection: the IEC AUTO-LOCK™! The Auto-Lock™ is an internal retention mechanism that actually hooks to the pins of power supply inlets and resists any axial force unless the Auto-Lock™ mechanism is released!  Tremendous amounts of force cannot get the electrical connector to budge, but as soon as...

Industry Information

NEMA Power Cords

NEMA power cords, or National Electrical Manufacturers Association power cords, plugs and connectors are the standard electrical plug used in North America, especially in the United States and throughout much of Canada. NEMA is an American-based organization formed in 1926 which sets the standards for electrical components and systems to adhere to and maintain.

Almost all of the electrical plugs and electrical receptacles used and sold in the US abide by the manufacturing and material quality standards set by NEMA. An important result of this is the increased consistency and expectations between electrical component manufacturers and consumers. The two most common NEMA standard connectors are the 1-15P and the 5-15; these are plugs with a body typically made of molded rubber and prongs made from steel or brass with a zinc, tin, or nickel coating. The 5-15 is used typically for general electrical devices and light-weight power loads. These are found broadly in homes, commercial and office applications. Other NEMA connectors carry different variations on these two common plugs, with more or differently placed prongs and increasing voltage capacities. The twist-locking L series and most other connector types are used for industrial purposes, and the types of connectors coincide with various types of use and voltage. For example, some types of locking connectors are used in boats, where there is movement and it is important that power connection not be lost or exposed where water damage could cause a short. The twist-lock cannot be pulled out of its outlet unless it is twisted open.

Devices approved by NEMA are typically engineered to be one wire or two wire devices depending on whether or not a device is polarized or grounded. Different considerations to keep in mind when purchasing electrical components include: the intended use of the power supply cord, plug or connectors, the intended energy load and transfer that will be required and the device for which is it needed. As NEMA components are the standard for the US, other power cords and connectors will be required if there is to be any travel or exposure to an international power source. Plug adapters and international power cords are widely available, but are not always required to meet NEMA standards and therefore it will still be important to consider individual manufacturing and material quality. Increased safety features and requirements are another benefit of having NEMA manufactured products available, and this is an important element missing from appliances that do not adhere to NEMA standards. Safety features on many NEMA parts include tamper resistant receptacles to reduce electrical shock, and grounding capabilities, especially in plugs which are intended for use in potentially wet areas such as out of doors, kitchens or basements in which a grounding capability will cut off the flow of electricity.
