Note 2: Installation category, called over-
voltage category, specifies impulse
withstand voltage. Category II is for
electrical equipment.
Pollution degree indicates the degree
of existence of solid, liquid, gas or
other inclusions which may reduce
dielectric strength. Degree 2 is the
normal indoor environment.
