Diversity factor
From Electrical Installation Guide
The term diversity factor, as defined in IEC standards, is identical to the factor of simultaneity (ks) used in this guide.In some English-speaking countries however (at the time of writing) diversity factor is the inverse of ks i.e. it is always ≥ 1.
