Cause of short circuit in the main circuit of the distribution box
The main cause of a short in an electrical circuit is damaged or exposed wiring, often made worse by age, moisture, or pests. Catching the signs early can help prevent costly damage and keep. A short circuit is a circuit that helps current to move over a path that has low or zero electrical impedance, which causes high current flow in the circuit. Normally, electrical current flows along a safe, designated path. It is often caused by damaged insulation, faulty appliances, water leaks, loose connections, incorrect wiring, or overloads, and can occur in outlets, extension cords, fans, appliances, and outdoor. An electrical short circuit occurs when a low-resistance connection forms between two points in an electric circuit—typically when the “live” (hot) wire contacts a neutral or ground wire. Like a domino effect, it is difficult to stop, which can cause such dangerous events as overheating of wires, damage to equipment or even fire.
