4)
This voltage is
– for functional insulation: the highest impulse voltage to be expected on the clearance (see 3.1.4);
– for base insulation, if directly or mainly influenced by transient overvoltages of the low-voltage network (see 2.2.2.2, 2.2.2.3.1 and 3.1.5):
– for other base insulation (see 2.2.2.3.2): the highest impulse voltage which may occur in the circuit
– for reinforced insulation, see 3.1.5.
Preferred values, as determined in 2.1.1.2
For PC board connectors, the values of pollution degree 1 apply, except for the fact that the value must not be below 0.04 mm as determined in table 4
The minimum clearances for the pollution degrees 2, 3 and 4 are based on experience, not on basic knowledge
