Leviton makes it easy for you to comply with the 2008 NEC mandate for TR receptacles in all new residential housing. This requirement resulted from a Consumer product safety Commission study that reported alleged injuries in the home caused each year by children attempting to insert foreign objects into receptacles. TR receptacles have been mandated in pediatric care areas for over 20 years and have likely been successful in preventing electrical injuries. As a long-time manufacturer of tamper resistant devices, we are pleased to be at the forefront of this safety measure with an expanded product line that encompasses a wide range of TR devices in residential and commercial Grades. As more states and municipalities adopt the 2008 NEC code, we expect it to have a major impact on your market. Although there is an increase in cost per product, it is negligible compared to the priceless value of protecting children. To smooth the transition and help you meet your new construction needs, we provide a handy cross-reference of standard and TR catalog numbers on the following page.
