Which amperage is NOT commonly recommended for disposal according to NEC standards?

The national electrical code (NEC) provides guidelines for electrical installations, including recommendations for various equipment ratings and standards for safety. In this context, amperage levels such as 5.6, 15, and 9.8 are commonly associated with specific applications and equipment.

The reason 19 is highlighted as not being a commonly recommended amperage relates to standard practices in electrical engineering and device compatibility. Electrical devices and circuits often utilize rounded values for amperage ratings, which tend to conform to circuit standards and safety regulations. The other options represent standard circuit breakers or devices that can normally be found in residential or commercial electrical applications, making them appropriate for disposal under NEC guidelines.

In summary, the selection of 19 signifies that it does not align with typical amperage ratings used in electrical equipment, leading to its classification as an outlier in terms of disposal recommendations by NEC standards.
