What is the minimum calculated service load for 1-9 KW electric range installed in a dwelling unit?

• A. 5KW
• B. 8KW
• C. 10KW
• D. 7.5KW

Answer: (B)

The minimum calculated service load for a 1-9 KW electric range installed in a dwelling unit is specified as 8KW. This figure is derived from the National Electrical Code (NEC), which outlines requirements for household cooking appliances. When determining the service load for electric ranges, the NEC provides guidelines that suggest using 8 KW as the standard load for any range in this power category. This approach ensures that the electrical service is adequately designed to handle the anticipated load while also considering demand factors that may reduce actual usage during peak cooking times. Selecting 8 KW helps ensure that circuits are not overloaded and that there is sufficient capacity for other household electric loads. Proper calculations and adherence to these codes contribute to improved safety and efficiency in residential electrical installations.
