HPN power cords are electrical cables suitable for AC-rated voltages of 300V and below. They are used for powering household appliances, electric tools, and various mobile electrical equipment. HPN power cords are made of rubber, which makes them flexible and suitable for frequent bending. They have certain weather resistance and oil resistance, making them suitable for outdoor use or in environments with oil contamination. HPN power cords are available in different colours, including black, white, and gray.

What You'll Learn
HPN-R power cords are used for indoor appliances
The HPN-R power cord is just one of many types of power cords available on the market. The National Electrical Manufacturers Association (NEMA) has established a standard for power cords in North America and some other countries, with amperages ranging from 15-60 and voltages from 125-600. NEMA codes indicate the plug configuration, with the first number representing the number of poles and wires, and the voltage. For example, NEMA 1 devices are 2-wire non-grounding devices rated for 120 volts, while NEMA 5 devices are 3-wire grounding devices rated for 125 volts.
In addition to NEMA, the International Electro technical Commission (IEC) has established designations for connectors used in appliances, computers, and laptops. IEC codes use the letter "C" followed by a number, such as C14 connectors commonly found on desktop computer power cords.
It's important to note that different countries and applications may have specific standards and regulations for power cords. For example, RV parks commonly use the NEMA TT-30 power cord type, which is rated for 125 volts. Understanding the specific requirements for your region and intended use is crucial to ensure safety and compatibility.
Overall, HPN-R power cords are designed for indoor appliances and offer a reliable power supply option within their specified voltage and temperature range.

NEMA codes indicate the plug configuration and amp rating
The National Electrical Manufacturers Association (NEMA) has a set of standards that specify which plug and receptacle configurations can be used with which amperages and voltages. These standards are designed to prevent "unsafe interchangeability" by making it physically impossible to plug a device into a receptacle that has the wrong kind of power for it.
NEMA codes have a two-part naming convention: a number before the dash and a number after the dash. The first number represents the plug configuration, which includes the voltage rating, the number of poles, and the number of wires. The second number represents the current rating in amperes. For example, the NEMA L5-30P is a locking plug with two poles, two wires, a current rating of 125 volts, and an amperage of 30 amps.
The second letter, which could be "P" or "R," indicates whether the connector is a "Plug" or a "Receptacle" (socket). For instance, the 5-15R is the common 125 V two-pole, three-wire receptacle rated for 15 A. The L5-15R, while sharing the same electrical rating, is a locking design that is not physically compatible with the straight-blade 5-15 design.
NEMA connectors refer to the power plugs and receptacles used in North America and other countries that follow NEMA standards. They are commonly used in IT equipment, electric vehicles, commercial kitchen equipment, and industrial machines.

IEC codes are used for computer and laptop connectors
HPN and HPN-R are types of power cord manufactured by Pshinecable and Tevelec. They are rubber power cords for indoor use with a rated voltage of 300V.
Now, onto IEC codes and computer and laptop connectors. IEC stands for the International Electrotechnical Commission. IEC connector standards ensure the interoperability and reliability of these connectors. IEC power cords are used to connect electrical devices to a power source safely and efficiently. They are known for their standardization, safety, flexibility, and replaceability. IEC codes can be identified by a number in the range of 60000 to 79999.
IEC 60320 is a standard for appliance couplers, which refers to both the appliance inlets and outlets, as well as the connectors on power supply cords. This standard allows manufacturers to produce the same appliance for many markets, with only the cord set needing to be changed for each market. IEC 60320 connectors are used for a wide variety of electronic equipment, including computers and their components, monitors, printers, and peripherals, as well as video game consoles, instrument amplifiers, and professional audio equipment.
The most common types of IEC 60320 connectors are the C13 and C14, often referred to as "kettle lead" or "computer power cord." The C13 connector features a three-pin design with a ground connection, making it suitable for high-power applications. The C14 connector is its counterpart and is commonly found on power distribution units (PDUs) and power supplies. It also has three pins and fits into the corresponding C13 socket.
Other types of IEC 60320 connectors include the C19 and C20, which are designed for high-power applications such as data centers and industrial equipment. The C19 connector has a higher current rating than the C13 and C14 and is often used with C20 inlets found on rack-mounted PDUs. The C20 connector is the counterpart to the C19 and is commonly found on power sources for devices with high-power requirements.
In addition to these, there are also C5/C6 connectors, also known as "cloverleaf" or "Mickey Mouse" connectors, and C7/C8 connectors, known as "figure-8" connectors.

Prime extension cords have letter designations for approved use
Each PRIME® extension cord has a letter designation that defines its type and approved use. These letter designations refer to the different features of the cord, such as its material, voltage rating, and resistance to the elements.
The "S" designation, for instance, indicates that the cord is a Hard Service flexible cord for general use and is 600-volt rated. The "P" designation indicates that the cord has a parallel construction, with each conductor separately insulated, and is typically used in household extension cords, air conditioner cords, and low-voltage landscape cables. The "J" designation specifies that the cord jacket is the standard 300-volt insulation type used in most extension cords.
The "W" designation signifies that the cord is rated for outdoor use, with the insulation and jacket compounds meeting specific temperature ranges. The "UL" designation indicates that the cord is Underwriters Laboratories listed, and the "Water Resistant" designation is given to cords made with water-resistant materials.
Additionally, the "C(UL)" designation signifies that the product has been tested and certified to Canadian Standards, while the "FT2" designation indicates that the cord is flame retardant. The absence of certain letters also carries meaning; for example, the absence of the "J" designation indicates that the cord jacket is an extra-hard-service 600-volt insulation type, referred to as a "Double Jacket" cord by PRIME®.

The S designation on Prime cords indicates a flexible cord for general use
Each PRIME® cord has a letter designation that indicates its type and approved use. The "S" designation on Prime cords indicates that the cord is a hard service flexible cord for general use. This means that the cord is approved for a wide range of applications and can be used in a variety of settings.
The "S" designation is typically followed by other letters that provide additional information about the cord's characteristics and approved use. For example, the letter "J" indicates that the cord has a standard 300-volt insulation type, while the absence of "J" indicates that the cord has a 600-volt insulation type with an extra-hard service jacket.
Another important letter designation is "T" or "E", which relates to the material used for insulation and the jacket. "T" indicates that the insulating material is PVC (vinyl) thermoplastic, while "E" specifies TPE-thermoplastic elastomer rubber for both insulation and the jacket. This distinction is crucial as it determines the cord's suitability for specific environments and applications.
Furthermore, the letter "O" is significant as it denotes that the cord is oil-resistant. This feature addresses a common issue with rubber cords, which tend to break down and lose insulating performance when exposed to oil or grease. This makes the "O" designation particularly important for cords used in automotive, industrial, or culinary settings where exposure to oil or grease is likely.
The "S" designation on Prime cords, indicating a flexible cord for general use, is a fundamental aspect that provides a foundation for understanding the cord's capabilities and approved applications. This designation sets the tone for the cord's versatility and adaptability across various contexts.
