What is the demand load for one household range with a nameplate rating of 10kW, 240V, 1Ø?

In determining the demand load for a household range with a nameplate rating of 10kW, it’s important to consider how demand loads are calculated according to the National Electrical Code (NEC) and relevant electrical standards. The NEC allows for certain demand factors to be applied to household cooking appliances.

For a range, the standard demand load calculation specifies that the first 12 kW of cooking equipment are usually taken at 100% of their capacity, but for loads exceeding this, a demand factor is applied. However, for normal household ranges, the demand load is typically understood to utilize a lower demand factor for estimation purposes.

In practice, a common approach often taken is applying a demand factor which can be around 80% for ranges. Thus, if we take 10 kW and apply this demand factor, the calculation would yield 8 kW (0.8 x 10 kW = 8 kW).

Therefore, the correct demand load for the household range in question, when following these conventions and calculations, is indeed 8kW. This allows for a more efficient understanding of how much energy the range will consume during use rather than the entirety of its nameplate rating.
