the earth wire was split into the 2 cables . Thankyou for your help I managed to join the live back to the wire that broke off. I manged to pull the existing wire out enough to join . Must have done correctly as fuse box not blown and no smell of electrical burning and have been using socket...
The double socket has 2 lives, 2 neutrals and 1 earth when connecting wires to socket one of the live wires broke off in the cable, still have 1 live wire i can attach. Can anyone advise what i should do ?
