What power rating is a NEMA L5-30 receptacle designed to accommodate?

The correct power rating for a NEMA L5-30 receptacle is 125 volts at 30 amperes, which aligns with the first option. This type of receptacle is typically used in applications that require a reliable power supply for equipment, such as generators or certain motor starters. The NEMA L5-30 configuration features a grounding pin and is designed for 125V applications, making it suitable for many loading scenarios.

The other options represent different voltage and phase configurations that do not match the specifications of the NEMA L5-30 receptacle. For instance, the second option involves a higher voltage of 208 volts and is not compatible with the standard used for this type of receptacle. Similarly, the specifications for 220 volts and 440 volts in the remaining options are beyond the design of the L5-30 standard, which is strictly rated for 125 volts. Understanding the significance of proper receptacle ratings is crucial for safely connecting equipment to electrical supplies, ensuring that devices operate effectively without risking overload.
