\nThe rules for creepage distance<\/strong><\/a> are much more complicated than those for clearance<\/strong><\/a>, and the requirements in clause 29 are also more complicated. Regarding creepage distance, I think if readers can understand the above information, it is sufficient for implementing the IEC 60335 series of standards. The requirements for creepage distance in clause 29.2 will be introduced in detail when introducing clause 29.2.
