Doing new supplies for a school new Shneider 3 phase & N MCCB panel board. 50mm 4 core SWA one end made off in the board earth fly lead from banjo to earth terminal. The other end gland made off in gland (fly lead not made off yet) 3 phases and neutral just hanging there. Done installation resistance test to earth at 500v got 10Mohms to earth on all phases run is about 50mtrs?
 
What is it connected into at the board that’s made off? Thinking you’re reading through equipment.

Either that, or the cables damaged somewhere

You mean INSULATION resistance test Mate surely
 
Did you try drying the exposed surface of the insulation between the bared ends of the cores and the gland? 10MΩ could just about be caused by condensation.

I think 'vgi' should read Vigi, Schneider's trade mark for their residual current add-on actuator.
 
you're correct pete. obviously your senile dementia is less advanced than mine. :D:D:D.

Could be that Tel, as well as my unhealthy addiction to anything SI FY except Dr Who, because it's not real like Star Trek.

What proved it wasn't real for me was the aerodynamics of the Tardis, impossible for a shape like that to fly let alone Time Travel, ludicrous.
