What is UL 1655 Ed 2?

UL 1655 Ed 2, also known as the Underwriters Laboratories Standard for Electric Baseboard Heaters, is a technical specification that outlines safety requirements and test methods for this specific type of heating device. Electric baseboard heaters are commonly used in residential and commercial applications to provide localized warmth. They consist of a long, narrow electric resistance heater element enclosed in a metal housing.

Importance of UL 1655 Ed 2

The UL 1655 Ed 2 standard plays a crucial role in ensuring the safety and performance of electric baseboard heaters. Compliance with this standard assures users that the devices they are installing or purchasing have undergone rigorous testing to meet established safety benchmarks. It also sets guidelines for manufacturers to follow during the design and production process, helping to reduce the risk of fire, electric shock, and other potential hazards associated with these heating devices.

Key Requirements of UL 1655 Ed 2

UL 1655 Ed 2 covers various aspects related to the construction, installation, and operation of electric baseboard heaters. Some key requirements outlined in the standard include:

Temperature limitations: The standard defines maximum allowable surface temperatures to prevent burns and potential damage to surrounding materials.

Electrical components: It specifies insulation requirements and tests to ensure that electrical connections and components can withstand specified voltages and currents without posing a risk.

Fire resistance: The standard establishes criteria for evaluating the fire resistance of the housing materials used in electric baseboard heaters.

Thermal protection: To prevent overheating, the standard mandates the inclusion of thermal cut-offs or other protective devices that interrupt power supply when excessive temperatures are detected.

Conclusion

In summary, UL 1655 Ed 2 is a technical standard that sets safety requirements and test methods for electric baseboard heaters. Compliance with this standard ensures that these devices meet established safety benchmarks, reducing the risk of fire, electric shock, and other potential hazards. By specifying construction, installation, and operational guidelines, UL 1655 Ed 2 plays an essential role in regulating the manufacture and use of electric baseboard heaters in residential and commercial settings.
