"The customer is not always right, but they are always the customer."
Most of the telecommunications providers require NRTL lab certification because they are not familiar with the other laboratory certification agencies. This has to do with risk management. They are afraid of "Garage Labs." Most carriers are self insured. Having a product certified and listed by a NRTL is a "comfort level" to the companies marketing and management.

For instance, one of the messages says that the NEC gives an electrician the right to unplug an un-NRTL-marked piece of equipment. Another message states that the NRTL's mark is the proof of product safety. Courtland's original question asked about products that were not NRTL marked. I want to follow that a little more. His original posting considers a product that is safety tested by a third party lab. The product has passed the third party safety certification. However the lab is not an NRTL. So the product just says "Conforms to UL 1950" or some similar verbage. 1. Are other certifications from other labs, such as A2LA and/or NVLAP allowed as long as there is a test report? 2. Does it matter what the voltage rating of the product is? 3. For products with external AC power supplies, would the NRTL mark need to be on the supply and the product? Or the supply only? 4. Does it matter where the product is used? (home, farm, factory ...) If the answer to the above questions are "No", "No", "Yes" and "No" then, theoretically, every piece of electronics in use in the United States would have been NRTL tested and marked. The tone of the answers in this thread sounds like this is true. But I believe it isn't. Am I whacked here?
