[IEC 61439 for LV equipment April 16th 2020 webinar] - Maximum rating to Insulating Resistance for routine test

[PascalL]

Question from Daniel Deveze

In the Webinar presentation, there is an information to the change to the maximum rating current to an assembly, to perform an insulation resistance to routine test. Can you explain more?

[PascalL · Accepted solution]

Hello,

As introduce during this webinar, the IEC 61439 edition 3 shall be published before mid of 2020. In the actual edition 2 for the routine test regarding dielectric performance the assembly manufacturer is authorized to perform an insulating resistance to assembly up to the rating 250A. For upper rating he has to perform a dielectric test. In the next edition 3 the rating is moved up to 630A. For upper rating he has to perform a dielectric test.
