What type of receptacle is designed to prevent the insertion of foreign objects?

• A. Standard receptacles.
• B. Tamper-resistant receptacles.
• C. Grounding receptacles.
• D. Weatherproof receptacles.

Answer: (B)

Tamper-resistant receptacles are designed specifically with safety features that prevent the insertion of foreign objects. This design includes internal shutters that only open when a two-pronged plug is inserted, making it difficult for children or others to insert objects that could pose a risk of electric shock or short-circuiting. Such receptacles adhere to safety standards set to mitigate hazards, especially in residential settings where children are present.

Standard receptacles do not offer this safety feature, leaving them vulnerable to accidental insertion of objects. Grounding receptacles focus on providing a path for fault current to safely discharge, while weatherproof receptacles are designed to withstand environmental conditions but do not address the concern of foreign object insertion. Thus, tamper-resistant receptacles are the best choice for enhancing safety in residential wiring.
