causes:-
faulty installation: Old or damaged insulation allows neutral and live wires to touch, which can cause a short circuit. Nail and screw punctures as well as age can cause wire casings or insulation to deteriorate and allow short circuits.
Loose connections: Attachments can loosen, sometimes allowing neutral and live wires to touch. Fixing faulty wire connections is difficult and sometimes requires working with live wires.
Household pests: Animals like mice, rats and squirrels sometime chew on wires. This can cause neutral and live wires to cross and result in a short
