Link between one light fitting and socket circuit?

If its in the hall then look "above" in all the obvious places inc the airing cupboard, because thats almost certainly off the socket circuit.

The airing cupboard just has one outlet for the boiler on a radial, most annoyingly the rooms all have laminate down and are full of furtniture, it's going to be fun!

The biggest concern Is that I could have never found it if on the same rcd, so would I be at fault? I'd say probably not as I follow dead testing to a t and do the whole job and still didn't pick this up.

It does sound very odd! If it was a borrowed neutral with that socket circuit then why does the light still work when that socket circuit is disconnected at the CU? Sorry to state the obvious Tom, but when you say disconnected, you did mean the neutral as well?

Perhaps that light is connected to both the neutral of that lighting circuit AND the socket circuit, hence the tripping, but working once the sockets are disconnected!!

You MUST update us Tom.. I cant stand it when we dont get to hear the end of the story. :smile5:

I would drop one of the legs of the ring out at the board and split the legs on a socket at roughly midway point and repeat the process on the sockets until I found what leg the borrowed neutral is connected to.

far to sensible for a friday evening. STOP IT!.

But why does the light still work when the socket circuit is diconnected from the CU?

If the circuit feeding the sockets has been disconnected at cu, and the light is still working it can't be linked.

Did you try it with all of the other lights switched off and just the hall light switched on?

I must of missed that, where does it say that?

More to the point why were you changing a CU when you should have been in church?

In church? I doubt very much he'd have a clue where to start on an MICC installation. I'm not sure you'd be able to work in a church today anyway, isn't there some sort of religious nonsense going on this weekend?
