UL+CUL Solar Cable

UL (formerly Underwriters Laboratories) is an American safety consulting and certification company that has played a major role in the adoption of electricity by the American public and in the ongoing drafting of safety standards for electrical equipment and components, including cables. The CUL mark is the UL mark for products sold in the Canadian market. Cable products with this mark have been certified to comply with Canadian safety standards, which are essentially the same as those cited by UL in the United States.
