NEMA 5-15P power cords come with various connector configurations to accommodate different device requirements. Some of the most common connectors include:

C13 to NEMA 5-15P: This cable connects devices with a C13 inlet, such as computer power supplies, monitors, and printers, to a NEMA 5-15R wall outlet. The C13 connector is a three-pin female connector that is widely used in IT equipment and other electronic devices. It has a curved notch on one side to prevent improper insertion and is rated for 250V and 15A.
C5 to NEMA 5-15P: The C5 to NEMA 5-15P cord links devices with a C5 inlet, commonly found on laptop power adapters and smaller electronic devices, to a NEMA 5-15R receptacle. The C5 connector, also known as a "Mickey Mouse" connector due to its shape, is a three-pin female connector designed for devices with lower power requirements. It is rated for 250V and 2.5A.
NEMA 5-15P to IEC320 C15: This power cord joins a NEMA 5-15R outlet to devices with a C15 inlet, such as gaming consoles, projectors, and some medical equipment. The C15 connector is a three-pin male connector that is similar to the C13 but with a slightly different shape to prevent accidental interchanges. It has a curved notch on one side and is rated for 250V and 10A.
NEMA 5-15P to IEC320 C19: The NEMA 5-15P to IEC320 C19 cable connects a NEMA 5-15R receptacle to equipment with a C19 inlet, typically used for high-power devices like servers, power amplifiers, and large printers. The C19 connector is a three-pin female connector designed for devices with higher power requirements. It has a curved notch on one side and is rated for 250V and 16A.
NEMA 5-15P to NEMA 5-15R: This power cord extends the reach between a NEMA 5-15R outlet and a device with a NEMA 5-15P plug. It is commonly used as an extension cord or to replace a worn-out or damaged power cord on an appliance or electronic device. The NEMA 5-15R receptacle has two parallel slots and a round grounding hole, designed to accept the NEMA 5-15P plug securely.
NEMA 5-15P to NEMA 5-15R x 2: A NEMA 5-15P to NEMA 5-15R x 2 cord splits one NEMA 5-15R outlet into two, allowing you to power multiple devices from a single wall receptacle. This configuration is useful for reducing cable clutter and maximizing the use of limited outlet space.
NEMA 5-15P to NEMA 5-15R x 3: Similar to the previous configuration, this power cord multiplies one NEMA 5-15R receptacle into three, providing even more flexibility for powering multiple devices. This setup is ideal for workstations or entertainment centers where multiple devices need to be powered from a single outlet.

Cord Gauge and Length Considerations

When selecting a NEMA 5-15P power cord, it is essential to consider the appropriate cord gauge and length for your application. The gauge of a power cord refers to the thickness of the internal wires, which determines the cord's current-carrying capacity and resistance to heat and voltage drop.

Cord Gauge: NEMA 5-15P power cords are available in various gauges, such as 18 AWG, 16 AWG, 14 AWG, and 12 AWG. A lower gauge number indicates thicker wires and a higher current-carrying capacity. For most household appliances and electronic devices, 18 AWG or 16 AWG cords are sufficient. However, for high-power devices or longer cord runs, 14 AWG or 12 AWG cords may be necessary to ensure optimal performance and safety.
Cord Length: The length of the NEMA 5-15P power cord should be chosen based on the distance between the wall outlet and the connected device, as well as the specific application requirements. Cord lengths can range from 1 foot to 100 feet or more. It is generally recommended to use the shortest cord length possible to minimize voltage drop and reduce clutter. However, for applications where the device needs to be moved frequently or positioned far from the outlet, a longer cord may be necessary.

 

Safety and Compliance Standards

 

To ensure the safety and reliability of NEMA 5-15P power cords, they must comply with various industry standards and regulations. Some of the key standards and certifications include:

UL 62: This standard covers flexible cords and cables intended for use with appliances and other devices. It specifies requirements for materials, construction, and performance to ensure the safety and durability of the cords.
UL 817: This standard applies to cord sets and power supply cords, including NEMA 5-15P cords. It covers requirements for electrical and mechanical properties, as well as marking and labeling.
CSA C22.2 No. 21: This Canadian standard is similar to UL 62 and covers the safety and performance requirements for flexible cords and cables used with appliances and other devices.
RoHS: The Restriction of Hazardous Substances (RoHS) directive limits the use of certain hazardous materials in electrical and electronic equipment, including power cords. NEMA 5-15P cords that are RoHS compliant are made without these restricted substances, such as lead and mercury.
