What is the minimum calculated service load for 20-8 KW electric ranges installed in dwelling units?

The minimum calculated service load for 20-8 KW electric ranges installed in dwelling units is determined based on the requirements outlined in the National Electrical Code (NEC). According to NEC guidelines, when calculating the service load for electric cooking appliances, the total watts of the appliances must be considered.

For ranges, the calculations typically indicate that a specific amount of load, in this case, for multiple ranges that total anywhere from 20 to 8 KW, results in a higher minimum service load requirement to ensure that the electrical infrastructure can safely handle the demand. When these ranges are added together, they yield a sum total that aligns with the 35 KW figure.

Ultimately, this requirement ensures that homes are adequately equipped with a service load that accommodates modern cooking appliances without posing a risk of overloading the electrical service. In this context, the choice reflecting 35 KW properly represents this calculated requirement, making it the correct answer for the minimum service load for the specified electric ranges.
