lead sheathed cable

[brucelee]

Hi all

my friends brother rang me to say he had drilled a hole in the wall and the power to lights has gone off

yes he has drilled the cable to be fair to him it was in back bedroom of 2 up 2 down terraced house
side of the window and not were yo would expect a cable to be

anyway I went to have a look and chased a bit of plaster off around the cable to see he had drilled a perfect hole bang in the middle of the cable and when i looked closer noticed it was lead sheathed

is it possible in anyway to repair this or should the damaged cable be replaced
I have told him its really old possibly around the 1940s and the house could do with rewiring

it has wylex fuseboard but with the replacement trip switches

on lead sheathed cable does the lead act as a earth?

I havnt had much experience of lead sheathed cables apart from ripping it out on rewires

if i do replace the faulty cable what do i do about the earthing regarding the cpc ? and then does this need rcd protecting all lights 1 circuit no rcd at present

any help and advice appreciated
my thought on it is a rewire for the whole house as it all looks original apart from newer switches and sockets

I hope you saved the wood. A good cabinetmaker would have the holes invisibly filled and knocked out as a coffee table at £450 by now!

and a wood butcher of today would leave the holes in an use it as a chisel rack

and it's one of the few times you'll find R2<R1.

so maybe i was wrong about the Zs probably being high as i posted earlier in this thread tel? csa of the cpc (lead sheath) being much greater than a modern pvc..................:hanged:
