Applied Research Laboratories Product Listing
Why do I need a listing?
Most cities and municipalities in the United States currently require equipment installed to be "Listed" and "Labeled" by an approved testing agency certifying its safety in regards to fire, shock, and personal injury in accordance with minimum safety requirements.
If your equipment is installed within a jurisdiction and an inspector notes there is no required listing mark from an approved testing agency, that inspector has the authority to refuse the equipment and deny approval of any installation containing that equipment. At that time, the equipment must either be removed and replaced by a listed piece or be tested and labeled by an approved agency.
Therefore, the lack of a listing mark on a small inexpensive piece of equipment can easily delay completion of a multimillion dollar project. Obviously, customer satisfaction would be severely affected.
