I appreciate threads like this. Thanks for sharing and I’m glad you are ok.
The chances are that if it was a pre work discussion about the products I’d have done exactly what you did.
Obviously an RCD would have made this nicer for you or possibly prevented it remaining energised in the first...
As above, it generally isn’t worth your time to find out. If it’s a standard bulkhead that still has a tube (and isn’t LED) the chances are it’s overdue replacement anyway.
So basically, just replace it!
I'd be thinking about stripping the outer sheathing off, using the existing 10mm L and N then either:
-crimping the CPC onto singles. Then you only need to get Yellow/Green singles.
-possibly using the galv conduit as a CPC?
As the conduit will need earthing anyway, and as 10mm T&E has 4mm...
I had a variation of this issue recently. I had test adapters for most of them but I didn't have a 4 pin 63A with 3 phases and earth, and no neutral. It was the same kind of switch.
If you don't have 16A single phase and TPN adaptors to trailing 13 amp sockets I'd make some for future use.
In...
Good news
That's the correct way to do it. Always leave earths in.( I've had a screw connect live and bonded steel before now which wouldn't be picked up just testing the circuit on it's own.)
No need if every circuit is testing fine independently L+N -> E, it won't tell you any more.
Agreed...
The 'white wire' looks as though someone has used a yellow/green earth wire to send a switched live to the outside light which is both naughty and dangerous.
I agree it should be looked at by someone competent.
If photo 3 is showing the right hand switch for upstairs landing light then it is...
You want the main switch off for your own safety, especially if testing something that isn’t quite making sense.
Are you IR testing L+N to the CPC bar, or disconnecting the cpc from each circuit and testing to that?
(You should test to the CPC bar in case there’s a fault to something that’s...
It's particularly painful when chances to play with MICC are rather low for most of us, and the chance to do a neat re-pot and gland job would have had me salivating over my joy-stripper. (thought I'd better add a hyphen there)
Is CU and Gas under the stairs? Or in corner of front room, or over the front door?
Random ideas:
Cellar?
Floor void under ground floor?
Lift landing floor boards, through airing cupboard to loft, down back of house?
D-Line trunking, under kitchen cupboards?
