    Kitchen Extractor Hood Isolation Location?

    C2 for no bathroom fan local isolation switch ?

    How can this be justified as far as I am concerned it would be a C3 at the most or no code as the MCB can be deemed for isolation (it's fed from the local lighting circuit). Surely C2 potentially dangerous - urgent remedial action required is a bit over the top, thoughts please !!!!!!

    Basic safe isolation question.

    Testing domestic consumer units. Is a dead test actually a dead test if the fuse is not pulled or an isolator switch supplied by a DNO is not open. Don't worry, I'm not about to mess about with this stuff unsupervised, til I'm competent.
