damaged swa cable

[currie123]

hi,

had a customer call me after he put a spade through his armoured cable supply to his garage, wants me to joint cable undergroung which is fine i thought, obviously using the appropriate jointing kit etc, but now he has asked the question if a socket could be added at the damaged point of the cable (as oppose to jointing it underground) , and fixed to the wall beside it, obviously this is not common practice but cant think of anything wrong with this providing the garage supply cable is rcd protected and cable is appropriately sized and correct size of mcb at the fuseboard.havent been to the job yet, but i am guessing a 6mm 3 core and 32a mcb set up.

any thoughts?

What size breaker is protecting this swa

 

[Farmelectrics]

Just seen breaker size you need to check personally I wouldn't do it now you can scotch cast this cable or you could run a new swa in would it be easy to run new cable in and give him an outside socket from another circut

hi ,

i dont actually know the answer yet but assuming it was a 32a mcb wired in 6mm 3core swa ?

 

[currie123]

scotch cast?? ok mate thanks i wouldnt be tool keen on doing it either but when i thought about it i wasnt sure why it wouldnt be possible

You won't have any spare cable to add a socket, you'll have to join a peice in to add a socket.

customer reckoned there would be enough spare but im not sure, dont think its a great idea anyhow

ip66 socket with mcb?

If he's cut burried SWA cable with a spade he must have strong muscles, but seriously you'd need a good "extra" 1m to bring it to the surface, terminate twice and rebury so exactly how deep is it?

Without looking it's hard to say, if there's enough cable MF IP67 junction box which will allow you to spur off for the socket (SWA rated to take =>32A).

And tell the gorilla to put his very sharp spade away...

 

[currie123]

Not as deep as recommended in regs anyway! Seriously I'm going to check the job tomorrow and take it from there, I think if he's keen on an outside socket il give him a quote for putting one in a more sensible way, and joint his armoured cable underground suitably! Thanks

If the area is prone to water saturation then you'll have to go the full IP68 route, seen a couple of installs recently that were fine until the summer came along.

 

[currie123]

Yes i would do the underground joint with one of the in line resin joint kits

 

[ackbarthestar]

I'd agree, use a torpedo, then back in the ground and run a separate circuit via swa to supply the socket.

I can't see how there would be enough spare cable to provide a socket above ground, unless you use a resin Y/T joint and insert a spur.
