What is UL 476 ?

UL 466 is a technical standard that specifies the requirements for power outlets and socket-outlet units. The standard was developed by Underwriters Laboratories (UL) to ensure the safe use of electrical devices by consumers.

The primary 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. The standard covers various aspects of outlet design, construction, and performance.

Safety Features Specified in UL 466

UL 466 specifies various safety features that are required to be included in power outlets and socket-outlet units. These features include:

* A clearly labeled "NEMA 5-15R" or "NEMA 5-23R" classification, which indicates the type of equipment and its intended use.

* An effective grounding system, which provides a low-cost path to ground for electrical equipment.

* A grounding configuration that is easily accessible and provides a clear indication of the grounding system.

* A grounding test procedure that ensures the equipment passes the test and is free from electrical hazards.

* The use of non-metallic materials for the enclosure and the conductors, which are less likely to cause electrical fires.

UL 466 also establishes requirements for the design, construction, and testing of power outlets and socket-outlet units. These requirements include the use of fire-resistant materials, the provision of adequate ventilation, and the use of test procedures to ensure the equipment meets the necessary safety standards.

Impact on Various Industries and Consumers

UL 466 has a significant impact on various industries and consumers. The standard ensures that electrical devices are safe to use, reducing the risk of electrical fires, electrical shock, and other safety hazards.

For example, in the U.S., UL 466 has been implemented in power outlets and socket-outlet units used in residential and commercial settings. By requiring the use of fire-resistant materials and providing clear labeling of the equipment, UL 466 has helped reduce the number of electrical fires and injuries.

Similarly, in Europe, the standard has been implemented in various electrical equipment, including socket-outlets, switches, and other fittings. The standard has helped reduce the number of electrical accidents and has improved the overall safety of consumers.

Conclusion

UL 474 and UL 466 are important technical standards that have helped ensure the safety and reliability of electrical devices. By specifying safety features and requirements for power outlets and socket-outlet units, these standards have helped reduce the number of electrical accidents and injuries. By following the guidelines set out in these standards, consumers can feel confident in the safety and reliability of the electrical devices they use in their homes and businesses.
