True or False: The ampere rating of a range receptacle can be based on a single-range demand load according to NEC Table 220.55.

The assertion that the ampere rating of a range receptacle can be based on a single-range demand load according to NEC Table 220.55 is accurate. NEC Table 220.55 provides specific guidelines on how to calculate the demand load for cooking appliances, considering that actual usage is often lower than the maximum capacity.

When determining the necessary ampere rating for a range receptacle, it is standard practice to reference the demand load rather than simply relying on the full rated load of the appliance. This allows for proper sizing of the receptacle and circuit, ensuring safety and efficiency. The table takes into account various factors, including the number of appliances and their expected usage, which is crucial for residential wiring practices.

Using demand load as a basis also recognizes that not all cooking appliances will be in use simultaneously at their maximum capacity. Thus, this approach aligns with NEC's intent to promote energy efficiency and safety in electrical installations. The guidance provided by NEC Table 220.55 helps electricians and code compliance professionals determine appropriate equipment and wiring sizes to meet both safety standards and real-world usage scenarios.
