Creepage distances, clearances and distances through insulation
29.1
60335-1(ed.3)
Question:
In table 13 there are no values for creepage distances and clearances for working voltage
between 250 V and 480 V for reinforced insulation.
Which values shall be considered in this case?
Rationale:
See question.
Decision:
The values are determinated by extrapolation, with the following formula: 8 x (working
voltage)/250.
