Afternoon all, just after a bit of advice!
The MCB for my downstairs (and landing) light started tripping the other day and now won't go back in. There is a direct short between the live and earth (0.09 on the IR) whereas the live/neutral is 204M and the neutral/earth is 194M
.
As a commercial electrician/HV type, I've not had much training or much understanding on how the domestic guys wire houses, how they decide which ceiling rose is first, which is last etc so is there any proper pattern to it or is it just a case of disconnecting at each rose and testing another one until the fault disappears?
As you can see above (for some unknown reason it's up there ^^^ ) I have drawn a (highly) technical drawing showing the layout and where the ceiling lights, wall lights, CU, and the direction of the first cable run for the lighting circuit.
Any advice (and not too much mocking!) would be appreciated!
Cheers
