(T/F) Receptacle contacts are offered in four primary designs to accommodate different configurations based on the amperage and voltage of a device.

• A. False
• B. True
• C. Not specified
• D. Depends on device

Answer: (A)

Receptacle contacts aren’t limited to four basic designs. The way a receptacle is configured depends on the standards it follows (such as NEMA, IEC, or other regional types), whether the connection is straight-blade or locking, and the required electrical ratings (amperage, voltage), as well as grounding and safety features. There are many different contact geometries to fit different plugs and outlets across various applications and regions. For example, in the US you’ll see straight-blade types like 5-15R and 5-20R for common 120 V service, plus locking variants like L5-20R or L6-30R for higher voltages and currents, and internationally there are additional connector families. Because of this variety, claiming there are exactly four primary designs to cover amperage and voltage configurations is not accurate.
