What is UL 817:2007

UL 817:2007, also known as the "Standard for Safety of Cord Sets and Power Supply Cords," is a widely recognized and accepted safety standard in the electrical industry. It sets specific requirements for cord sets and power supply cords to ensure their safety and performance. In this article, we will delve into the technical aspects of UL 817:2007, exploring its key provisions and discussing why it is essential for manufacturers, consumers, and regulatory authorities.

The Purpose and Scope of UL 817:2007

The primary purpose of UL 817:2007 is to minimize the risk of hazards associated with cord sets and power supply cords while they are in use. It covers various types of cords, including those used for household appliances, computers, and medical equipment. The standard applies to both detachable and permanently attached cord sets and power supply cords.

Key Requirements of UL 817:2007

UL 817:2007 establishes comprehensive requirements for cord sets and power supply cords, covering various aspects such as construction, current ratings, voltage ratings, insulation resistance, mechanical strength, and grounding provisions. These requirements aim to ensure that the cords are safe, durable, and capable of handling the intended electrical loads without overheating or causing electrical shocks.

Certification and Compliance

Manufacturers should obtain UL certification to demonstrate compliance with UL 817:2007. UL conducts rigorous testing and evaluation of cord sets and power supply cords to verify their compliance with the standard's requirements. Products that successfully pass the testing process receive the UL Mark, which signifies their safety and reliability. This mark instills confidence in consumers and allows manufacturers to market their products more effectively.

In conclusion, UL 817:2007 plays a vital role in ensuring the safety and performance of cord sets and power supply cords. Manufacturers should strictly adhere to the standard's requirements to provide consumers with safe and reliable electrical products. Consumers, on the other hand, should look for the UL Mark when purchasing cord sets and power supply cords, as it guarantees that the product meets all the stringent safety standards mandated by UL 817:2007.
