What rating of a range receptacle can be based on a single range demand load?

The correct answer focuses on the amperage rating of a range receptacle, which is critical for safely supplying power to an electric range. The National Electrical Code (NEC) allows the demand load calculations for household cooking appliances to be based on their amperage requirements, as this directly correlates to the amount of current the receptacle can handle without overheating or creating a safety hazard.

When sizing a receptacle for a range, it is essential to consider the amperage because it determines the amount of current the circuit can carry. The demand load is reduced from the total connected load based on typical usage patterns; therefore, calculating the required amperage provides a practical way to ensure that the receptacle and its associated wiring can safely supply power during operation.

In comparison, while voltage, power, and frequency are important electrical parameters, the specific need for amperage here is rooted in the requirements for safely carrying the electrical load of a range. Voltage relates to the potential difference and must match the appliance specification, power combines voltage and amperage to represent wattage, and frequency pertains to the oscillation of electrical currents but does not dictate the safe loading of the receptacle. Thus, the strength of the demand load for a range receptacle is inherently tied to its
