Recently been to a job to fix a D.I.Y fault on a lighting ring but can't figure ...
So , client rings , outside flood light stays on all day .. there's no switch and she doesn't know where the power comes from .. I find power using a wire tracker .. and it leads to a double switch in the living room , open it up to find ... 3 neutrals in a block .. 2 lives in comm .. and 1 live in L1 ... So all connected to 1 side of switch ... How do I move the outside light to the second side of the switch .. please advise

Hi - not sure I’ve understood correctly, but it sounds like either one switched L is leaving the switch going to all lights - or - the outside light L is one of the 2 L in the Comm. If you’ve got test gear, I’d safely isolate the circuit, take the 2 L out, see which one is permanent L and put that one back in Comm.

difficult to say remotely. need more info. does the light go off when you operate the switch? and a pic. would help. if in doubt, get a local spark in.

so what you do is split supply cables, find which one carries power, second cable put on COM of 2nd switch and make a jumper from known live on L1 to L1 of 2nd switch. Done

Is this a maintenance 'call out' or are you helping someone out?
Either way, are you qualified to do the work?
Are you sure it's a lighting RING circuit (doubtful)?

Agree what is a lighting ring?

At risk of stating the obvious, it's a lighting circuit in the form of a ring.

The only experience I have of such a circuit is the outgoing circuits from a 110V central battery system for emergency lighting, they were wired as rings to combat the voltage drop.

Are you assuming they are live from the wire colours? You can't. Electricity does not know what colour the wire is.

What you have is a typical loop in at switch circuit. The 2 wires in COM are live in and live out to next switch. In L1 you have a switched wire to the light. If the light stays on the switch is short circuit. This assumes you have found the right switch.

What's with the sarcasm? Calm down.

My 2p worth: someone has changed the original outside light for a PIR light, put the switched live in with the permanent live. The PIR has now developed a fault and is permanently on.

He said he was going to report back a week yesterday. He's either a DIYer or maybe an apprentice, without much experience, whose a bit frightened of getting back in touch. Whatever, he shouldn't have been 'finding power using a wire tracker' and needed assistance. I just hope he found some, for his sake and that of his 'client'.
Let us know OP.
