406.11 Tamper Resistant Receptacles in Dwelling Units.
In every kitchen, family room, dining room, living room, parlor, library, den, sunroom, bedroom, recreation room, bathroom, garage, basement, laundry and outdoor area, all 125-volt, 15- and 20-ampere receptacles shall be listed tamper resistant receptacles.

This is a dramatic and controversial code change. Tamper resistant receptacles are designed to prevent a child from being injured inserting a foreign object into the receptacle. Manufacturers use several different techniques to make their receptacles tamperproof. Many children have been shocked and badly burned by sticking keys, hair pins and other objects into receptacles.

No exceptions to this requirement are included. Receptacles for dedicated appliances, like refrigerator outlets, kitchen countertop receptacles, and other receptacle locations which are above the reach of a child are all included. In a dwelling unit, the receptacle outlets specified in 210.52 must be listed tamper resistant receptacles. Tamper resistant GFCI receptacles are available.

AFCI’s and tamper resistance receptacle requirements in the 2008 will increase the cost of wiring a single family home by about $1000 (estimate). Some of the changes to the 2008 NEC® are so controversial and increase the cost so much, that several states are either not adopting the 2008 NEC®, adopting the 2008 NEC® without AFCI requirements or reverting back to the 2005 NEC® if the 2008 edition was adopted.
