When fixing a light switch or socket and using wire nuts use electrician’s tape to ensure the wire nut does not come loose. Frequently the bare wires that are twisted and connected via a wire nut are still somewhat exposed. By wrapping electric tape around the wire nut, such that it extends down the sides of it and around a portion of the wire, you can prevent the remote possibility of a short circuit.
In addition, it is also a good idea to wrap the entire light switch or socket with a couple wraps of electrician tapes to insulate the switch or socket screws. Again, this will help prevent the remote possibility of a short in the event the metal screws associated with the electrical box come in contact with it.
