Starting January 1, 2010, Tamper Resistant Receptacles are required for all newly installed receptacles. Tamper-Resistant (TR) Receptacles are safer than other preventive measures:

  • Once installed, they are permanent, offering continuous protection unlike plastic outlet caps that can be removed.
  • Shuttered wall plates add layers of material between blades and receptacle contacts. Underwriters Laboratories (UL) has withdrawn its listing from tamper-resistant wall plates.
  • Tamper-resistant receptacles are certified and subjected to severe and documented testing procedures defined by UL.
  • Automatic protection whenever a plug is removed.

Tamper resistant receptacles add about a dollar to the price of the receptacle.
