Hi,
I passed my 236 P1&2 many years ago and I only ever worked on buildings, so no twin & earth for me.
Can anyone tell me if I would need to take any extra exams to do household work?
Many Thanks

What reasons can anyone think of why a circuit would have a dead short across all 3 conductors ?
so far I'm thinking
- water damage
- possible rodent / pest damage
any more ?

The only fault I can find is a 12K resistance between live and earth, I presume this is more that enough to trip the RCD, but was wondering at what resistance does the rcd trip with this kind of fault?
Or is...

The blue disc is linking between neutral and earth on the fitting. Never noticed these before...
