Hi, recently did a CU replacement. Tested before the change and circuits all good, but one odd thing I found is that the previous owner had installed his own version of a two-way switch for the hall light.
However, rather than using 3-core in a traditional arrangement so that either switch can turn the light on/off at any time, he has simply used T+E and wired the second switch in parallel to the first, meaning that either one will turn the lamp on if it is off but both switches need to be off to switch the lamp off (you get what I mean..!)
Now, certainly not good practise, but I don't see this as dangerous or a safety issue and client not particularly interested in having it rewired as the switches are barely 5m apart, so it has been left as is with a comment on the installation certificate.
Haven't come across this before and wondering how you would code it on a PIR.
Cheers!
