IR between live conductors & Earth

[Ross1]

When carrying out the test mentioned above what do you guys find the easiest and quickest when doing it on the whole installation ?

Main switch off, all mcbs on, link N bar to one mcb, 250v IR between N bar and E bar If all clear then again at 500v If a low reading then I first switch off each MCB at a time to try narrow the low reading down.


Edit, oh and if the propertys ocupied then i note as a limitation that no IR was taken between line and neutral.

Note: this is shown in its basic form and other things relating to safety and protection are carried out.
