Most common causes for short-circuit:
Faulty Insulation: 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.
Appliances: Old or broken appliances can develop shorts over time. Short circuits in appliances can occur in the plugs, in the power cords or inside the device.

Short circuiting might be caused when
• The live wire and neutral wires come in direct contact.
• When too many appliances are connected in single socket.
• Improper insulation can lead too extensive heating of appliance.
• Accidental hike in voltage and amount of current drawn.
• Multiple connections and socket created in a single line.
• Improperly placed fuse with inappropriate current rating.
• Improper earthing also causes fire accidents.
