What is the minimum calculated service load for 10-10.8 KW electric ranges installed in dwelling units?

The minimum calculated service load for electric ranges installed in dwelling units, specifically those rated between 10 and 10.8 kilowatts, is set at 25 KW. This value is established in the National Electrical Code (NEC) guidelines, which provide standards for electrical installations to ensure safety and adequate service capacity.

When determining the service load for electric ranges, the NEC accounts for the maximum capacity that might be required to operate these appliances efficiently. A 25 KW service load accommodates not only the operation of the range but also considers additional factors such as potential simultaneous use with other appliances and overall electrical demand within the dwelling.

By using this load calculation, it ensures that the electrical system is designed to handle the expected usage without the risk of overloading circuits, which can lead to potential fire hazards or equipment failure. Therefore, 25 KW is recognized as a standard for installations of this nature, making it the appropriate choice in this context.
