I put a fastener through a power cable. Can you cut and fuse the 13 amp cable beside a connecting block?
Only use a 30 amp three path fully enclosed T-junction box.
Thats one of those round ones with three lumps of brass and screw in them.
Next time buy yourself a metal detector and telecommunication and joist detector.
Saves a lot of trouble.

Thats what you need.
NO. You should not use a conencting block (sometimes call chocolate blocks).
If the cable is part of your ring major then you must use a 30A crossroads box and properly wire and in safe hands it. This could be a problem if it's in the wall.
Why not insert a 13A socket and pretend that this what you intended to do adjectives the time? You'll need a proper 'box' and support it nicely to the breeze block etc.
Answers: If this cable is in a wall you call for a junction box. If an extension cord, you can do something resembling that, but then it is susceptible to clamminess. A new extension cord isn't that expensive.
I judge if you have to ask the query you need to procure a qualified electrician. Dont mess with electricity as it could impose a fire or injury.
