Understanding Short Circuits: Prevention and Myths
When Paths Cross
A short circuit occurs when a low-resistance path not suited for electricity is created—usually when a 'Live' wire touches a 'Neutral' or 'Earth' wire due to insulation failure.
Common Causes:
- Rodent Damage: Pests chewing through wires inside the ceiling or wall conduits.
- Old Insulation: Standard wires typically have a 15-20 year lifespan before the plastic becomes brittle and cracks.
- Moisture Seepage: Mumbai's monsoon dampness entering electrical boxes and creating a conductive bridge.
Frequently Asked Questions (FAQ)
An MCB stops overcurrent, but for spark-level protection, you need an **AFDD (Arc Fault Detection Device)**, which is the 2026 standard for wooden-panelled rooms.
Switch off the Main Isolator immediately and call a licensed electrician. Do not try to find the spark yourself.
