Short circuits are behind most fires in India, yet most people only learn what one is after something goes wrong. Understanding the causes and the warning signs puts you ahead of the problem, because a short circuit almost always announces itself before it becomes a fire.
What causes a short circuit
- Damaged or aged insulation that lets wires touch.
- Loose connections in sockets, switches and boards.
- Overloaded circuits drawing more current than the wiring can handle.
- Water or moisture reaching live wiring.
- Pests chewing through cable insulation.
The warning signs
- Breakers or fuses that trip repeatedly.
- A burning or plastic smell near outlets.
- Scorch marks, warmth or discolouration on switches and sockets.
- Buzzing sounds or sparks from fittings.
- Lights that flicker or dim for no reason.
How to prevent short circuits
- Use quality, ISI-marked wiring and fittings, and replace damaged cords.
- Avoid overloading circuits and extension boards.
- Keep electrical points away from water.
- Fit good MCBs and ensure proper earthing.
- Have old wiring inspected by a licensed electrician.

Cover the fire you cannot predict
Even a well-maintained home can develop a fault, often inside a wall or panel where you will never see it coming. An automatic fire extinguisher ball beside the switchboard is the safety net, putting out a short-circuit fire on its own in 3 to 10 seconds. See the FireXross 1.5 Kg ball.
