Is UL approval required for electrical products in the US?

UL approval is not legally required for all electrical products in the U.S., but it is highly recommended and often expected by consumers, retailers, and insurers. UL (Underwriters Laboratories) certification indicates that a product has been tested for safety and meets specific standards, which can enhance consumer confidence and marketability. Many states and local jurisdictions may have their own safety regulations that require compliance with recognized testing standards, which often include UL certification. Thus, while not mandatory, UL approval is a valuable asset for electrical products.
