What is UL 496B?

UL 496B is an important technical standard in the electrical industry. It specifically focuses on requirements for lampholders, commonly known as light bulb sockets. This standard provides guidelines for the design and construction of lampholders, ensuring their safety and compatibility with different types of light bulbs.

Ensuring Safety

One of the primary purposes of UL 496B is to ensure the safety of both the users and the electrical systems they are connected to. The standard specifies various tests that lampholders must undergo to meet safety requirements. These tests include checking for adequate insulation, resistance to heat, and protection against electric shock. Compliance with UL 496B means that the lampholder has passed these rigorous safety tests.

Compatibility and Performance

Another crucial aspect covered by UL 496B is the compatibility and performance of lampholders with different types of light bulbs. This includes factors such as appropriate fit, secure connection, and reliable electrical contact. The standard also considers factors like temperature rise and proper support for the weight of the light bulb. In short, UL 496B ensures that lampholders can efficiently and safely accommodate a range of light bulb types.

Global Recognition and Compliance

UL 496B is recognized globally as a standard for lampholders and enjoys widespread adoption in the electrical industry. Its strict requirements and comprehensive testing procedures provide assurance to manufacturers, retailers, and consumers that the products meet established safety and performance criteria. Compliance with UL 496B is often indicated by the UL listing mark, which displays the manufacturer's commitment to quality and safety.
