    domestic PIR no end to end reading on Neutrals

    Domestic PIR (TN-S, 60A MAIN, 16MM EARTH, MAIN BONDING 6MM). Neutrals on end to end test at a S/O give zero ohms, Live gives 0.30 ohms & cpc gives 2.7 ohms at same S/O. I'm thinking that if this is a ring then the Neutral is loose somewhere on this cct. Any advice please - i may be overlooking...

    When NOT to take neutrals to switches

So 4 neutrals blocked in a connector block, which was then put behind the switch as there was no room inside (only a 25 mm back box used), and the feeds had to blocked as 'the installer' could not get...

    Neutrals at switches

    Went to a job today, twin and earth, and it had been wired 2 plate, which of course meant that all the switches had the neutral taken to them. WTF, if I had done that in my apprenticeship I would have been kicked off site. Is this how things are done now, god I hope not.
