On October 12 Underwriters Laboratories (UL) issued a public notice alerting consumers, retailers, manufacturers, regulatory agencies and AHJs to the presence of four communications cables that bear unauthorized references to UL. "The communications cables have not been evaluated by UL to the appropriate Standard for Safety for the United States, and are not authorized to bear the UL Mark or any reference to UL," the notice stated.
One of the four cables listed in the notice is the one we told you about in February, which has copper-clad aluminum conductors. Two of the other three cables in the alert also have copper-clad aluminum conductors.
