What is the minimum service demand for 10-8 kW ranges in an apartment complex?

The minimum service demand for a set of kitchen ranges in an apartment complex is determined using the demand factors outlined in the National Electrical Code (NEC). For residential applications, the demand factor for ranges is used to calculate the expected load.

In the case of 10 ranges rated at 8 kW each, one would typically not use the full rated capacity of each range for the service demand calculation because, in practice, not all ranges will be used at their maximum load simultaneously. The NEC provides a demand factor that allows for this calculation to be reduced based on the total number of ranges.

For the first four ranges, you would take the full load, which is 32 kW for 4 ranges. For the next six ranges, a demand factor is applied, which reduces the expected load significantly. According to NEC table, typically, the total demand for household cooking appliances can be calculated, resulting in a total service demand of around 27.2 kW for 10 ranges.

Using this context and understanding of demand factors provided by code regulations, we confirm that 27.2 kW reflects a realistic load requirement for the complex, making it the appropriate choice.
