Repairing Ring Main


My son decided he would do a spot of DIY and managed to drill through the ring main cable using the hammer action on my Kango drill ... what was going through his head at the time (apart from 240 volts) I still don't know ... however ... he's ok but the feed and return cable are both chopped. What's the best and safest way of reconnecting these two wires? I know I'll need to chisel the plaster out around the cable but how do I extend and join the cables back together?

A rofessional would probably crimp connections, but simpler for you would be to connect using terminal block strip inside something like a choc box..as seen on Dragon's den!! ie http://www.tlc-direct.co.uk/Main_Index/Necessities_Index/Connector_Strips/index.html

That is not allowed if the joint is going to be plastered over.
Ash,
Have a look at
http://wiki.diyfaq.org.uk/index.php?title Κble_crimping
I do not think that there is anything on that page that I could add to. Even if you have to spend £20 on a crimping tool you are still better off than calling an electrician out.

Presumably because they are then 'not available for inspection'? Is that why?

Excellent article. You do need to spend the money on a decent ratchet crimper though, as you say £20. The cheaper ones don't cut the mustard.

Yes. Also screw terminals can become loose over time. Although I have worked on many 50 year old installations where the screw terminals are fine!

Like you, my son did the same several years ago, fortunately I managed to pull through enough cable to fit a socket outlet at the point. This is worth considering.
