UL cannot require a company to List or not List anything. In some cases I have Listed a Class 2 device and in some cases I have not depending upon the business case. I once called a major manufacture of Class 2 home intercom/radio equipment and asked what did. They indicated that they have never obtained Listing for Class 2 devices and electrical inspectors have never been a problem.
