What is the function of tamper-resistant outlets?

Tamper-resistant outlets are specifically designed to enhance safety, particularly in environments where children may be present. The primary function of these outlets is to prevent the insertion of foreign objects into the slots. This is achieved through internal shutters in the outlet that only open when a plug is properly inserted, thereby reducing the risk of electrical shock or injury that could result from someone trying to insert an object that doesn't belong there.

This design feature is critical for child safety since young children may be curious and attempt to insert toys, fingers, or other items into outlets, which can lead to severe accidents. Therefore, tamper-resistant outlets serve an important role in improving the overall safety of electrical installations in homes and public spaces.

The other options do not align with the primary function of tamper-resistant outlets. While increasing efficiency of electrical flow, allowing more devices to be plugged in, and minimizing wear and tear on devices are all valuable concepts in electrical installations, none of them pertain to the specific safety feature that tamper-resistant outlets provide.
