Which load is not included in the standard for receptacle ratings in residential settings?

  1. 150 W per receptacle

  2. 200 W per receptacle

  3. 100 W per receptacle

  4. 250 W per receptacle

The correct answer is: 200 W per receptacle

In the context of receptacle ratings for residential settings, the standard typically considers the load to ensure safe and efficient electrical usage while preventing overload. The values assigned to the load per receptacle are derived from common usage patterns and electrical safety regulations. The load of 200 watts per receptacle is not included in the standard because it exceeds the typical estimates for general-purpose receptacle usage, which are aimed at accommodating a normal range of appliances and devices without risking circuit overload. The standards commonly reference lower wattage figures. For example, loads of 150, 100, and even 250 watts might appear in other specific contexts but do not represent the mainstream residential guideline for general-purpose receptacles. By focusing on the most frequently used wattages, codes and standards help maintain safety and efficiency in residential electrical systems. Thus, the correct answer reflects the wattage that does not align with the commonly accepted figures for receptacle ratings in these settings.
