Notes :
4)
If insulated cable is used for the primary circuit, the voltage category could
be improved according to the insulation characteristics given by the cable
manufacturer.
e.g.
Cable insulation (primary) Category
HAR 05 600V CAT III
HAR 07 1000V CAT III
5)
Between primary (completely filling the aperture) and secondary.
