Are receptacle contacts available in multiple designs based on amperage and voltage?

The assertion that receptacle contacts are available in multiple designs based on amperage and voltage is indeed true. Receptacles are designed to handle specific electrical loads, which vary by application and the devices they are intended to support.

Different designs cater to various amperage ratings, such as 15A, 20A, and further up for specialized purposes, and each of these typically has distinct configurations to prevent mismatching of devices and outlets. Additionally, voltage ratings also dictate the design, as lower voltage systems (like 120V in standard residential settings) look different compared to higher voltage systems (like 240V or 480V used in industrial applications).

Thus, the multiple designs ensure that receptacles can safely manage the electric load they are rated for and work properly with the corresponding plugs.
