IEC Low Voltage Motors Guide
The minimum value measured must be according to standard IEC 61439-1 at least 1000 Ω/V with reference to the nominal voltage in relation to the earth of the circuit being tested. In practice, a target value of at least 0.5 MΩ should be used for 230/400 V assemblies and at least 1 MΩ above that. Using the methods of standard to design and test a switchboard avoids such problems as dielectric failure, reduced creepage or clearance, and other electrical safety risks. On the rare occasions that lightning strikes nearby, this can significantly increase the .
