Lutron Black 15 Amp Tamper Resistant Receptacle and Plug for Dimming use

Tamper resistant receptacles, unlike traditional receptacles, offer the added protection of a permanently installed, spring-loaded slider mechanism capable of resisting insertion of single pronged elements such as keys, hairpins, or nails while still allowing access to electrical plugs. Lutron Tamper Resistant Receptacles are compliant with article 406.11 of the 2008 National Electric Code NEC. The NEC prohibits the dimming of standard receptacles. The dimmable outlets of the Dual Dimming Tamper Resistant DDTR and Half Dimming Tamper Resistant HDTR are specifically designed to mechanically reject all NEMA standard plugs and thus can not be used for any other device fan, heater, vacuum, radio, etc. These receptacles will only accept the special mating Lutron replacement plug for dimming use RP-FDU . The result is an NEC compliant way to control a portable lamp with a dimmer.
