What are Power Supply Cords?

Power cords, also known as power supply cords, are flexible electrical cables that connect devices and appliances to a power source. They're most commonly found on appliances that don't come with a power cord, such as dryers, stoves, and computer displays.

The male connector or plug on one end connects to the electrical receptacle, wall outlet, or extension cord. The female connector on the opposite end is connected to the appliance or another male connector. In some appliances, this female connector is omitted and replaced by a permanent cable.

Power cords are commonly found in both residential and commercial settings. Every electrical appliance, such as televisions, laptops, refrigerators, and air conditioners, uses them. However, because most plant equipment takes a lot of electricity and requires medium to high voltages, power cords are rarely used in industrial and manufacturing plants. Current and voltage ratings of 16 A to 20 A and 125 V are normal for power cords.

Types of Power Supply Cords

Different types of power cords include:

AC Power Cords

This power cable is used to conduct electricity in the form of alternating current (AC) or electrical power with a sinusoidal waveform, as the name implies. The common electricity format in most, if not all, electrical outlets is an AC electrical system.

Custom Power Cords

These are power cords that customers have specially ordered. Not everything can be made accessible on the market due to the innumerable combinations of plugs, connections, and cord standards. Customization options are available from top power cord suppliers to suit specific needs.

Heavy Duty Power Cords

Extension Cords

These electrical cords are used to extend the distance between the power source and the appliance. On one end is a socket connection, and on the other is an electrical plug.

Power Cords for Generators

These are usually cords with a high amperage rating. Before the power is distributed to the utility system, their current rating can reach 50 A. Generator power cords must have the same power rating as the highest-rated generator outlet to avoid insulation breakdown.

Power Cords with NEMA Plugs

NEMA power cords are electrical cords that adhere to the National Electrical Manufacturers Association's requirements (NEMA). NEMA standardizes each power cord component's design. North, Central, and certain South American regions employ NEMA standards.

NEMA 5-15P Power Cords

On one end, these power cords have a Type B electrical plug. NEMA 5-15P refers to a 15-amp NEMA standard plug. Two flat, current-carrying pins (live and neutral) and one spherical earth pin make up the plugs.

Standards for Power Supply Cords

The different standards for power cords include:

International Standards IEC 60320

IEC 60320 is a collection of standards for power cables for appliances with a voltage of up to 250 volts. Even though each country has its own power cable types and regulations, the IEC 60320 is widely accepted as an international standard. The letter "C" stands for the IEC 60320 code standard for connections. Multiple connector types are provided for different combinations of current, voltage, and temperature. C14 to C13 and C20 to C19 are the most often utilized power cord kinds.

Europe: CEE 7/7 (Type E, Type F)

In several European countries, as well as those that follow the CENELEC standard, CEE 7/7 is now the de facto plug standard. Denmark (AFSNIT 107-2-D1), Ireland, Italy (CEI 23-50), Malta (BS 1363), Cyprus (BS 1363), Gibraltar (BS 1363), and Switzerland (SEV 1011) are among the European countries that do not adopt CEE 7/7. CEE 7/7 to C13, CEE 7/7 to C15, and CEE 7/7 to C19 are the most common power cords that use the CEE 7/7 plug.

North American: NEMA 5-15P (Type B)

The NEMA standards are widely used in most North American countries and a few others. The NEMA 5-15P plug is the most extensively used in sockets among the NEMA 5-15P plugs. They are three-wire circuits (hot, neutral, and ground) rated at 15 amps at 250 volts, though they're generally used with 110 volts.

The most common type is the Nema 5-15 standard NEMA 5-15P to NEMA 5-15R power cord. The plug is designated by NEMA 5-15P, and the receptacle is designated by NEMA 5-15R. NEMA 5-15P to C13 and NEMA 5-15P to C15 are two other commonly used NEMA 5-15 plug power cord kinds.
