Hello Mark, The first product that comes to mind is air fresheners. S. C. Johnson makes an direct plug-in air freshener with a pass through receptacle. http://www.glade.com/glade-plug-ins/ There is a list of acceptable devices that can be connected to the outlet and there appear to be few restrictions.
This product is covered under UL 283 - Air Fresheners and Deodorizers. This standard sets size and weight limits for direct plug-in devices. There is no requirement for the receptacle other than compliance with UL 498, the standard for receptacles. If you can get a copy of UL 283, see if the torque requirement matches UL 60950-1. If UL 283 has a lower torque limit, it would be an indication that the mass of the plug in the pass-through receptacle has been taken into account.

"Mark Gandler" <markgandler@hotm ail.com> To Sent by: [email protected] [email protected] cc Subject 04/12/2007 08:42 Safety requiremnts for pass through PM outlet devices Hi, is there any special UL product category or standard for products with pass through outlet? Let's say it is a powerline device with pass through outlet on another side. These are the challenges I see to certify this type of product: 1. 60950 section 4.3.6, direct plug-in or torque requirement. How is one will know what you will plug on another side? If the product weight around 0.3kg and you put another 0.5kg on top of it or in extension to it, it will definitely fail 0.25N.m requirement. Please comment if my assumption is correct. 2. To test an outlet himself. Do you test outlet only or together with the product? Product components will probably fail extensive temperature as a result of overcurrent test on the outlet. Does anyone know any products which were UL certified and what was/were the standard/s they used? Thanks, Mark MSN is giving away a trip to Vegas to see Elton John.
