When I recently set about renewing a light fitting, I isolated the lighting circuit before starting to ensure that there was no live power at the ceiling point.
During the process, the power tripped to the whole house. Apparently, I have been advised since that this was probably because I shorted the neutral and earth wires which remained connected to the main fuse box (and hence the RCD).
This has never happened to me before, so I presume this is a relatively new issue with more modern systems?
My main question is - apart from being really careful to avoid the bare wires shorting - is there any way I can do such a repair without having to switch off the whole housing circuit every time?
