- In another bedroom, I had to chisel out the ring main cable from a
concrete wall. This involved accidentally baring the cable in parts so I
decided to cut it off from the highest point I could and apply new cable. To
join old + new cable, I used 30 amp terminal blocks but over tightened some
so the metal cracked. The cables seemed to be fixed tight so I didn't worry.
Should I have?

Have you reburied these in the wall ?
