Demand Factor
Demand factor — the ratio of simultaneously used power to the installed one. Not all devices work at once — the panel would be oversized.

Why it is used
- The oven, washer and kettle do not work at the same time;
- The cable and breaker are selected by the calculated current, not the sum;
- For an apartment the demand factor is 0.6-0.8, for the office — 0.7-0.9, for industry — by process.
Example
Installed 15 kW, demand factor 0.7 → calculated 10.5 kW → at 230 V: I ≈ 46 A → input breaker C50, not C63.
