Types of Power Cords

There are many different types of power cords. These are usually used in consumer products, information technology equipment, and hazardous locations. They can be made from various materials, such as woven cotton or plastic, and can be either detachable or fixed to the appliance. A detachable lead is safer, because it doesn’t have a live protruding pin. They may also come with twist-lock features and other attachments. In addition, power cord sets may include accessories, such as fuses for overcurrent protection, a pilot light to indicate voltage, and a leakage current detector.

Depending on the environment in which they are used, power cords are usually suitable for interior applications. However, if the cords are meant for outside use, it is important to choose the right material. In addition, if the cords are to be exposed to harsh environments, they should be made from more durable materials. Besides, right-angle plugs are also available to prevent the cable from bending too tightly and causing excessive wear. Finally, retractable cords are great for tight spaces, as they can extend in length and return to their original size quickly.

While UL 498 is the most common standard for power cords, different countries mandate their own standards. In North America, the National Electrical Manufacturers Association (NEMA) develops standards and certification agencies such as UL and CSA. In North America, ITE cords carry NRTL certification marks, proving compliance with these standards. To avoid potential hazards, it is recommended to check for a RoHS or temporary lighting REACH declaration from the manufacturer.

The National Electrical Manufacturers Association (NEMA) defines the voltage capacities and plug types on power cords. In North America, NEMA types A and B are common. Type B plugs include a grounding rod. In Europe, CEE 7/7 sets standards for plugs and receptacles. These are the most common types of power cords used in household appliances. There are also many specialized types, such as NEMA 5-15R.

Some countries use different standards when deciding on power cords, including the IEC 60320 standard. The IEC 60320 standard specifies different types of connectors for voltage and current and also the temperature. Most common connectors are marked “C” for international use, while others are standardized for use in certain countries. If you’re not sure which cord is right for your device, ask the manufacturer to send you a sample. It’s important to check all the connections for compatibility and safety before purchasing.

A basic NEMA 1 power cord is made of two flat pins approximately five inches apart. Below these two pins is a round pin. The third pin is for grounding. This plug is also commonly referred to as a grounded plug. The NEMA 5-15P plug comes with multiple outlets and is used for a wide variety of applications. The plugs of NEMA 5-15P power cords are rated 15A at 250V.
