How many primary designs are receptacle contacts typically offered in?

Receptacle contacts are typically offered in three primary designs: the "hospital grade," "heavy duty," and "standard." Each of these designs serves different applications and environments, providing varying levels of durability, safety, and performance. The hospital grade design, for instance, is built to withstand rigorous demands in healthcare settings, while heavy-duty designs are used in industrial applications where robustness is crucial. The standard design is common for everyday residential and commercial use.

Understanding these designs is critical for selecting the appropriate receptacle for a specific application, ensuring both safety and functionality in electrical installations.
