Hi I'm on my last year of my apprenticeship and throughout my 3 years I've literally asked everyone I've worked with this question about pme systems.
if the PEN conductor fully breaks (near impossible I no because it's concentric but let's say in the metre for example) your return path is going to be anything bonded to earth if it's connected at a met not in a consumer unit as this way the current will still go through the rcd. Therefore causing everything bonded to become live and the system still working without a neatral?
The best answer I've had (from my tutor) is that the resistance would become so high that it would draw more current causing the rcd to trip but would it as the current would still be going in and out of the rcd?
Its obviously one of those things I don't need to no but it bugs me ha Ill anyone have a clear answer cheers
