It is very normal, particularly with novice electrical work, to see a screw terminal association or wire nut association where there is excessively (or excessively little) uncovered copper wire appearing at the wires. With screw terminal associations, there ought to be sufficient uncovered copper wire stripped to wrap totally around the screw terminal, yet less that abundance exposed copper wire reaches out from the screw. The abundance uncovered wire can short out in the event that it contacts a metal box or different wires. Wires ought to be folded clockwise over the screw terminals; on the off chance that they are switched, they can be inclined to releasing.
With wire nut associations, the majority of the uncovered copper wire ought to be covered up under the plastic top, with no uncovered wire appearing at the base of the wire nut.
The most effective method to Fix the Problem
Kill the ability to the gadget, at that point detach the wires and either cut off the abundance wire or strip off extra protection so the best possible measure of wire is uncovered. At that point, reconnect the wires to their screw terminal or wire nut. Pull daintily on the wires to ensure they are safely associated.
