Notes When calculating the heat dissipation, the quadratic relationship
of current with the rated diversity factor α must be considered.
Pv = I2 x R
Pv’ = Pv x α2
If no data is available concerning the load
relationships of the individual circuits, the
rated diversity factor is selected conform to
VDE 0660 Part 500.
