【Safety Certification】The Clearances, Creepage Distances and Solid Insulation in Product Safety
Appliances shall be constructed so that the clearances, creepage distances and solid
insulation are adequate to withstand the electrical stresses to which the appliance is liable to be subjected.
Do you know the different for clearances, creepage distances and solid Insulation?
Examples of Insulation
The conductive parts A and B are mounted on solid insulating material surface.
Clearance is the "line of sight" distance. Creepage distance path follows the contour of the groove.
