What is UL 917

UL917 is a widely used standard in the electrical industry. It plays an important role in ensuring the safety and effectiveness of electrical devices. In this article, we will explain what UL917 is and why it is important.

Understanding UL Standards

Before diving into UL917, let's first understand what UL standards are. UL, which stands for Underwriters Laboratories, is a leading global safety science company that certifies, validates, tests, and inspects various products to ensure their safety and quality. UL standards are guidelines developed by UL that outline requirements for specific product categories.

UL standards cover a wide range of industries, including electrical and electronic equipment, fire safety, chemical safety, and more. These standards are designed to promote safety, reliability, and sustainability in different sectors.

What is UL917?

UL917 is a specific UL standard that pertains to plug-in and cord-connected switches for use in the US and Canada. This standard applies to switches rated at 600 volts or less and intended for connection to branch circuits not exceeding 20 amperes.

The purpose of UL917 is to ensure that these switches meet all necessary safety requirements and function properly under normal operating conditions. The standard defines various technical specifications and performance criteria that switches must meet to achieve UL certification.

The Importance of UL917

UL917 plays a crucial role in ensuring the safety of electrical devices connected to switches. By adhering to UL917, manufacturers can demonstrate compliance with recognized safety standards, reassuring consumers and regulatory authorities.

Under UL917, switches are tested for potential hazards such as electrical shock, fire risks, and mechanical failures. Compliance with this standard ensures that switches undergo rigorous testing and evaluation to mitigate these risks. Additionally, UL certification provides assurance that the switches meet industry quality standards and will function reliably over their intended lifespan.

Moreover, UL917 facilitates market access for manufacturers. It serves as a common safety benchmark that allows products to be easily evaluated and compared by consumers, contractors, and other industry professionals. Meeting UL standards can give manufacturers a competitive edge by enhancing reputation and customer trust.

In conclusion, UL917 is an important standard that ensures the safety and reliability of plug-in and cord-connected switches. By adhering to this standard, manufacturers can demonstrate compliance with recognized safety criteria and provide consumers with confidence in the products they purchase.
