Hello,
I had the floor boards up today and noticed that the ceiling rose for the room below, was wired with 3 singles. Probably the whole house is like this, this is just the first one I've seen.
The house is a 1970's house so quite old with regard to the wiring, but I'm really curious what type of wiring method for the lights would make this work with only 3 single core cables going into it.
Assuming one goes to the switch, would it be a neutral in and neutral out and the third is the switched live? I would guess in that case the permanent live is only going as far as the switch.
So if that is the case, the neutral is doing the rounds via all the ceiling roses, and the live is doing the rounds via all the switches, all in separate single cores. And no earth at all?
The reason I'm so curious is that I thought I knew (or had a decent idea) about how lighting circuits are wired, but maybe only by modern standards. This one got me thinking.
Thanks in advance,
Neil
