Which key feature is common to both hospital-grade receptacles and tamper-resistant receptacles?

Both hospital-grade receptacles and tamper-resistant receptacles share a fundamental emphasis on safety in their design, making safety-focused design the key feature that is common to both. Hospital-grade receptacles are specifically engineered to reduce the risk of electrical faults in healthcare settings, where patients may be in vulnerable situations. They often include features such as additional grounding and sturdier construction to ensure reliability and lower the chance of electrical hazards.

Tamper-resistant receptacles, on the other hand, incorporate mechanisms to prevent foreign objects from being inserted into the outlets, significantly reducing the risk of electrical shock, especially in settings where children may be present. This design focuses on enhancing safety by preventing misuse.

While it is true that enhanced durability and weather resistance can be characteristics of specific receptacles, they do not define the primary purpose or feature that connects both hospital-grade and tamper-resistant receptacles. Standard voltage ratings are also common to many types of receptacles but do not highlight the unique safety features these two types specifically emphasize. Thus, the focus on safety in their design is what ties them together as essential protective devices in their respective environments.
