Tamper-resistant receptacles are designed to prevent what, and where are they required?

• A. To prevent moisture intrusion; required in basements.
• B. To prevent insertion of foreign objects by children; required in new dwelling units.
• C. To reduce energy usage; required in all existing homes.
• D. To reduce noise; required in kitchens.

Answer: (B)

Tamper-resistant receptacles are built with internal shutters that block the slots unless a proper plug is inserted, preventing objects from being pushed into the contacts. This design specifically reduces the risk of electric shock to children who might try to poke items into outlets. The code requires these devices in new dwelling units, ensuring that new homes have outlets that are less accessible to curious little fingers. The other options don’t fit because moisture control, energy savings, or noise reduction aren’t addressed by tamper-resistant outlets.
