What is the minimum calculated service load for 1-12 KW electric range installed in a dwelling unit?

To determine the minimum calculated service load for a 1-12 KW electric range installed in a dwelling unit, we reference the National Electrical Code (NEC) guidelines, which provide specific calculations for residential cooking appliances.

For electric ranges, the NEC requires a certain minimum load calculation to ensure that the electrical system can safely accommodate the appliance's requirements. For a range rated between 1 KW and 12 KW, the minimum service load calculation is generally set at 8 KW. This value is based on typical cooking demand in residential settings, taking into account factors like peak usage during meal preparation.

Selecting 8 KW as the minimum calculated service load ensures that the wiring and circuit protection can handle the power demands of the electric range while also considering potential simultaneous use of other appliances. This approach helps maintain safety and efficiency in the electrical system of the dwelling unit.
