Receptacle outlets (if known) and ﬁxed multioutlet assemblies (if any) are entered into the calculation, and if the load is great enough, a demand factor is applied. Load calculations in the National Electrical Code have evolved over many decades. It was in the 1933 NEC that load calculation requirements began to resemble a format that the modern code user would find familiar. Since then, many things have changed, but the primary requirement remains the same — service equipment and conductors must be sized to handle the expected load.
