such as sealed adapters or with lower grade ferrite core material,
this value may need to be reduced to 3600 Gauss due to the
higher operating ambient temperature. It is important to verify
that core saturation does not occur at maximum ambient tempera-
ture under overload conditions just prior to loss of regulation.
Maximum Primary Wire Diameter, OD (mm)
By default, if the override cell is empty, double insulated wire is
assumed and the standard wire diameter is chosen. The grey
override cells can be used to enter the wire diameter directly by
the user.
