Plug into safety with Leviton® line of tamper resistant receptacles. Leviton® makes it easy for you to comply with the current 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 , commercial, industrial and hospital grades.
