What is UL 466?

UL 466 is a technical standard that defines the requirements for power outlets and socket-outlet units. It was developed by Underwriters Laboratories (UL), an independent safety science company, to ensure the safe use of electrical devices by consumers.

The Purpose of UL 466

The main purpose of UL 466 is to establish minimum safety requirements for power outlets, so that they can reliably deliver electricity to connected devices without posing hazards such as electrical shock or fire. This standard covers various aspects of outlet design, construction, and performance.

Safety Features Specified in UL 466

UL 466 specifies several safety features that power outlets should have. One important requirement is the inclusion of a grounding feature, which allows excess electrical energy to be safely directed to the ground. This helps prevent electric shock, especially in the event of a short circuit or electrical fault.

Another key safety feature mandated by UL 466 is the provision of insulation between live parts and exposed conductive parts. This prevents accidental contact and reduces the risk of electric shock. Additionally, the standard requires adequate spacing between outlets to prevent overcrowding and minimize the chance of overheating or arc faults.

Testing and Certification Process

To ensure compliance with UL 466, power outlets undergo rigorous testing by accredited laboratories. These tests evaluate factors such as durability, resistance to heat and fire, resistance to mechanical stress, and overall performance. If an outlet meets all the requirements and passes the necessary tests, it receives UL certification, indicating that it has been deemed safe for use by consumers.

It is important to note that UL 466 applies specifically to power outlets installed in North America. Other regions may have different standards and certifications for electrical products.

In conclusion, UL 466 is a technical standard developed by Underwriters Laboratories to ensure the safety and reliability of power outlets. By complying with this standard, manufacturers can provide consumers with electrical devices that meet rigorous safety requirements, helping to prevent accidents and promote consumer confidence.
