Hi guys I'm looking for some advice. I have recently removed a wall socket that we no longer need, and have wrapped the individual Live, Earth and Neutral wires in electrician's insulating tape, and then wrapped the end of the whole cable in insulating tape, before cementing it back into the wall and plastering over it. Have I done the right thing? I am concerned, because, the circuit breaker for the wall sockets tripped off this morning, and then later on this afternoon the main breaker tripped off . During this afternoon, I have noticed that the lights around the house are flickering intermittently (although these are on different circuits). Could these issues be related to me plastering over the live cable, or could it be a coincidence? Thanks in advance, Ken.
