Have a new build to finish of etc
Doing the testing
Got a ring main, with a short circuit to every earth including main earth and bonding except the ring main earth
Continuity tests .... All good
End to end tests ..... All good
Cross connects .... All good
Every other circuit all dead tests, no issues what so ever.
All circuits pass insulation tests when testing seperatly.
Just a measure, carried out a global insulation test and this fault cropped up.
Was narrowed down to the ring main.
Removed the ring main, tested it all fine. Once the ring is put into the board it fails tests insulation resistance to any earth is around 0.04M ohm
It is a new build, I installed all wiring and everything went in as it should be.
The earthing system is PME
80amp main fuse
Any ideas?
Might not be clear above, but its a bit hard to explain.
should i just power up and see what goes ............. bad day explode
